Patent JP-S60210847-A (JP)
Title: Manufacture of semiconductor device
Inventor: KAGAWA KEIICHI
IPC: H01L21/822
Filed: 1984-04-04
Abstract: PURPOSE:To easily obtain a substrate covered with a region increased in resistance in the part other than the element active region by a method wherein, in formation of an ingot, the element-forming regions and the regions containing a high-concentration impurity capable of reducing the resistance on heat treatment and the like are alternately provided. CONSTITUTION:A P type Si element-forming region 21 of approx. 10<15>/cm<3> is formed to a required thickness, and a P<+> type or N<+> type Si region 22 of 10<18>/ cm<3> or more is formed to a required thickness. Further, it is sufficient that they contain Si that can change to the donor or the acceptor on a later irradiation with radioactive rays or heat treatment, the isotope or neutrons of a well- known element for impurity, O, C, etc. The regions 21 and 22 are formed alternately. A region 21 where the element is to be formed is exposed by cutting and is then finished to a required thickness. Preparation of a C-MOS device on this substrate hardly necessitates consideration for latch-up even under the increase in integration because the bottom of each element is joined with a low-resistant layer. It is also advisable to reduce the resistance by activating the neutrons after element formation. This construction improves concentration control, leads to mass production, and shortens the processing time.

Inventor: KURIYAMA JOJI
IPC: H03G5/16
Filed: 1988-03-18
Abstract: PURPOSE:To simultaneously flatten both frequency-to-phase and amplitude characteristics by comparing a signal waveform which gets through a filter having a desired frequency characteristic with a signal waveform picked up by a microphone and executing an adaptive signal processing so that both of the signal waveforms may become the same. CONSTITUTION:A microphone 14 is oppositely arranged on the front face axis of the front face of a speaker 13 and they are coupled in an acoustic space. A signal delay circuit part 15, a characteristic setting part 16 to set and adjust a transfer function to set the desired frequency characteristic, and an error detecting part 17 to detect the error of the output signals of the characteristic setting part 16 and the microphone 14 and to supply an error information signal to an adaptive digital filter part 11 are connected in sequence between the microphone 14 and a sound source signal input terminal part 10. The adaptive digital filter part 1 adjusts the amplitude and phase frequency characteristics of the filter by itself so that a mean value that the value of the error information signal obtained from the error detecting part 17 is squared may become minimum.

Title: Constant velocity universal joint
Inventor: KADOTA TETSUO
IPC: F16D3/2245
Filed: 1999-03-12
Abstract: PROBLEM TO BE SOLVED: To reduce the rotational resistance and to ensure the good feeling by specifying the axial pocket clearance gap between a pocket of a holding unit and a torque transmission ball. SOLUTION: A holding unit 4 comprises three window-shaped pockets 4b for accommodating the torque transmission balls 3. The 'clearance gap >=0' is satisfied when an axial dimension of the pocket 4b is L, a diameter of the ball 3 is DBALL, and the axial pocket clearance gap between the pocket 4b and the ball 3 is δ=L-DBALL, whereby the rolling characteristic of the balls 3 can be improved, and the rotational resistance of a joint can be reduced. When the clearance gap δ is excess, the guiding function of the balls 3 by the holding unit 4 is impaired, and the constant velocity of the joint can not be kept. By keeping the optimum range of the clearance gap δ within a range of 0<=δ<=55 μm, both of the rotational resistance and the feeling can be properly kept.  The rotational backlash can be prevented by a pre-load application means for reducing the clearance gap between the ball and a ball track, and the compact and lightweight universal joint can be manufactured with the low cost.

Filed: 1987-03-20
Abstract: PURPOSE:To separate an input/output (I/O) device having a fault from a system by rewriting a time-out logical address by a I/O device having the succeeding logical address at the time of detecting the time-out during integrated polling. CONSTITUTION:An I/O controller 11 sends an integrated polling frame (c) to I/O devices 12-14 and a timer counts up a previously determined time. When the I/O device 13 generates a fault or is disconnected from a power source during integrated polling, the timer does not receive a response frame from the I/O device 13 after receiving a response frame from the I/O device 12, so that the timer is turned to a time-out state. At the time of time-out in the timer, the I/O controller 11 rewrites the logical address of the I/O device 14 by that of the I/O device 13 to separate the I/O device 13 from the system.

Title: Method for controlling pressure of mechanical seal and control device thereof
Inventor: KADOWAKI ISAMU
IPC: F16J15/34
Filed: 1988-03-23
Abstract: PURPOSE:To maintain proper pressure at a sealing portion according to operational condition by using an electromagnet as a means for applying pressure and adjusting turning on electricity for the electromagnet based on at least one of the detected value of temperature at a sliding portion or the neighborhood thereof, temperature of sealing fluid and leak quantity from the sliding portion. CONSTITUTION:In case that temperature detected by a sliding portion temperature sensor 12 is higher than a predetermined temperature, or the difference of temperature between that of sealing fluid and said temperature, a controller 9 controls electricity to an electromagnet 18 to lower sealing pressure to reduce force for pushing a load transmitting shaft 20 and to reduce the pushing force of a stationary ring 2 for lowering temperature at the sliding face. In case that leak quantity detected by a leak detector 13 is more than allowable value, electricity to the electromagnet 18 is controlled to increase the sealing pressure to increase the force pushing the load transmitting shaft 20 and to increase the pushing force of the stationary ring 2 for reducing the leak quantity. Accordingly, proper pressure of a sealing portion can be maintained according to operational condition which influences on the property and the life of a mechanical seal.

Title: Oil stove with electric heater
Inventor: NAKANO KAZUHIRO
IPC: F24C1/02
Filed: 1982-04-21
Abstract: PURPOSE:To make it possible to reduce the heating cost and to finely adjust the room temperature according to the temperature of external air by incorporating an electric heater in an oil heater and controlling the operation of the electric heater by a thermostat. CONSTITUTION:When the room temperature is low, kerosine oil is burnt in a combustion cylinder 3, and power is supplied to an electric heater 6, whereby the room temperature can be increased in a short period of time by the sum of combustion heat A of kerosine and heat B generated by the electric heater 6. Then, when the room temperature increases, a power source switch of the electric heater 6 is opened by the action of a room thermostat. Hence, heating within the room is maintained by the combustion heat A of the kerosine and rapid lowering of the room temperature is not caused but the room temperature can be maintained at an appropriate value. When the temperature of external air is comparatively high, the room temperature can be maintained at a suitable value by switching ON-OFF of the electric heater 6 without burning kerosine, and wasteful use of energy can be prevented.

Title: Transmission device
IPC: G11B20/12
Filed: 1992-03-25
Abstract: PURPOSE:To improve the picture quality of a reproduced image in a monitor TV, etc., in which a sequential processing is performed for data by suppressing error propagation. CONSTITUTION:On a recording side, a recording is performed by adding address data to code data. On a reproducing side, an error correction circuit, 93 detects the errors in reproduced data and outputs the address of an error block to a zero data preparation/control circuit 86. In a switch 88, zero data to which an error flag is added from a switch 87 and a data length adjusting bit are inputted, and the output of the error correction circuit 93 is inputted by being delayed by a delay circuit 85. When the output of the delay circuit 85 is an error block by being controlled by the zero data preration/control circuit 86, zero data in place of this error block is outputted and further, an output data rate is made constant by outputting an adjusting bit. By this, the picture quality of a reproduced image to be displayed on a monitor TV, etc., is improved even when the reproduce data is discontinuous.

Title: Toner concentration control device of developer
Inventor: TERAJIMA ISAMU
IPC: G03G15/08
Filed: 1978-06-07
Abstract: PURPOSE:To detect and control the amount of developer with a simple constitution by providing the developer sensitive element comprising constituting a feedback- oscillating circuit through the use of electric coils, in the specified position of a developer vessel and controlling the establishment or not of oscillation conditions with the level of the developer. CONSTITUTION:A developer level detector 14 integrated with a coil unit 20 and a circuit unit 21 is provided to the bottom plate 2 of a developer vessel. The circuit unit 21 consists of a feedback-oscillating circuit, a rectifier circuit and an amplifying output circuit. If the mix ratio (concentration) of the magnetic carrier and colored toner in the developer is within the specified range, the developer level is high and the magnetic influential power acting upon the detector 14 is large, hence the coupling coefficient between electric coils 20a, 20b is large and the feedback- oscillating circuit oscillates as its oscillation conditions are established. When the colored toner is consumed, the developer level becomes lower than the mounting position of the detector 14 and the coupling coefficient between the coils 20a, 20b becomes small, resulting in the failure of establishment of oscillation conditions. The oscillation then stops.

Title: Dust treating mechanism
Inventor: HOSAKA MASAYA
IPC: B02C19/00
Filed: 1989-03-20
Abstract: PURPOSE:To decompose the fine particles of dust to hyperfine particles and to prevent the defect arising from the dust by providing an optical system which forms the ray film by the laser light from a laser light source in a vacuum or gas space where the treatment of a material to be treated is executed. CONSTITUTION:The laser light beam LB projected from the laser light source 1 is made incident to the position apart from the center of a cylinder into, for example, a cylindrical optical system 3, the inside surface of which is formed as a reflecting mirror surface, in the direction perpendicular to the cylinder axis. The LB reflects successively on the reflecting mirror surface 2 within the optical system and forms the LB ray film 4 in the direction perpendicular to the axial direction within this region. The fine particles 5 consisting of metals, compds., ore, etc., are ground and evaporated by receiving the energy of the LB at the time of passing the LB film 4 when the above-mentioned particles are made incident into such region by the falling movement by gravity, Brownian movement, etc., as shown by an arrows 6. The particles are thereby decomposed to single crystals or the hyperfine particles 7 of several nm. The fine particles of the dust are decomposed to the hyperfine particles in this way, by which the number of the fine particles of such a size as to generate the pollution hazards is decreased and the product yield and reliability of semiconductor devices are improved.

Abstract: PURPOSE:To minimize the extent of frictional force working on an interval between an endless belt and a sheet separating member as well as to expand an adjustable range of pressing force of the endless belt against this sheet separating member by setting a contact engaging spot of the sheet separating member to one side of the endless belt travel part down to a midpoint between a driving roller and a driven roller. CONSTITUTION:A contact engaging spot of a sheet separating member (reversible roller) 44 to one side of an endless belt (40) travel part is set down to a midpoint between a driving roller 32 and a driven roller 34. With this constitution, a contact angle of the sheet separation member 44 against the endless belt 40 becomes minimized, and frictional force working on an interval between the endless belt 40 and the sheet separating member 44 is minimized. Consequently, an adjustable range of pressing force of the endless belt 40 against the sheet separating member 44 can be thus expanded.
