IPC: H03H7/24
Filed: 1984-03-21
Abstract: PURPOSE:To execute setting with a high accuracy within a limited adjusting resistance value range by providing a register circuit for storing control information of BCDm+1 digits. CONSTITUTION:A register circuit 20 of BCDm+1 digits makes every digit and the whole have a coefficient of 10<-1>-10<m-1>, and 10<n>, respectively. In this state, in case when an adjusting resistance value range has been limited to the minimum 800 and the maximum 2.2K, 2K is connected to the uppermost resistance of a resistance group 23, and thereafter, precise resistances of 1K, 800-0.8 and 0.4 are cascaded. Subsequently, when a selecting signal 25 of a switching circuit executes a selection so that 2 of 10<3> can be selected from a switching circuit C38 by A and B, a relay contact to which a necessary resistance value has been connected through a switching circuit group 24 and a relay circuit group 21 opened and closed by information stored in the register 20. As a result, a fine adjustment can be executed. Accordingly, setting can be executed with a high accuracy within a limited adjusting resistance value range.

Title: Device for sealing rotating shaft
Inventor: MORI MASATSUGU
IPC: F16J15/16
Filed: 1994-02-28
Abstract: PURPOSE:To compact a device so as to reduce the number of part items by providing a movable holding member which sandwiches an elastic seal ring of V-shaped cross section between it and a sealing device main body along the direction of the axis of the ring to deform the ring, and a fluid pressure actuator for moving the movable holding member along the direction of the axis. CONSTITUTION:While a rotating shaft 1 is being stopped, a movable holding member 8 is pressed upwards by a pressure spring 10 and a V-shaped seal ring 7 is sandwiched between the annular projection 12a of a main body member 12 and the annular recess 8b of the movable holding member 8 along the direction of its axis. Since each projection 12a and the recess 8b have their inclination angles set to greater values, the seal ring 7 is deformed in a direction in which its bore becomes smaller than before the pressing, and the seal ring 7 makes contact with the rotating shaft 1, creating a complete seal. This seal prevents oil leaks and entering of dust. To rotate the rotating shaft 1, compressed air is supplied from the inlet 15a of a fluid supply passage 15 to a fluid pressure chamber 9 during startup, so as to lower the movable holding member 8 against the pressure spring 10.

Title: Linear valve
Inventor: IHARA KIYOKATSU
IPC: F16K3/32
Filed: 1998-03-06
Abstract: PROBLEM TO BE SOLVED: To control the rate of flow with a minor operation force by converting a rotational input into a linear output. SOLUTION: A linear valve includes a cam mechanism of such a structure that steel balls 9a and 9b are fitted into semicircular grooves 14a and 14b which are furnished at the counter-input side end face of an input shaft 1 in such a configuration that the depth reduces in the rotating direction. By this cam mechanism, a slide 3 is operated which has a rate-of-flow control part in which the rotation of the input shaft 1 is movable in the output shaft axial direction, and the rotating motions of the input shaft 1 are converted into linear motions of a slide 3 in its axial direction, and thereby the degree of opening of the flow passage is controlled.

Title: Induced plasma generating method and apparatus
Inventor: MIYAMOTO MASAHIRO
IPC: H05H1/46
Filed: 1995-03-15
Abstract: PURPOSE:Not to use a high frequency electric power as an arcing source by emitting a seed gas which is made to be plasma previously by d.c. voltage from one end of an insulating pipe in the axial direction and applying a.c. current with 500kHz or lower to a coil in the outer circumference of the insulating pipe. CONSTITUTION:When voltage is applied to a pair of electrodes 103 while a seed gas 7 blown to the inside of an anode 102 being blown to the inside of an insulating pipe 22 through a nozzle 108, the seed gas 7 near the nozzle 8 is converted into plasma state by voltage pulses. After the voltage pulses disappear, the plasma state is maintained by applying d.c. voltage and furthermore the plasma jet 107 is extended downward. Induced plasma is generated due to induction current induced in the insulating pipe 22 by a second coil 15 connected with an a.c. electric power source 14. Since the electric power source 14 is a low frequency electric power source with 500kHz or lower, the temperature distribution of the plasma in the radius direction becomes uniform and thus plasma with larger diameter than conventionally generated plasma becomes available practically. As a result, the installation can be made compact and economical and the efficiency for surface treatment can be improved.

IPC: H01J61/48
Filed: 1979-05-07
Abstract: PURPOSE:To obtain a flurorescent lamp free of failure e.g., blacksih brown spots, by suppressing the occurrence of blakish brown spots by the method in which the layer of a fluorescent substance is coated on a conductive film by dividing it into two layers or more, each having different average grain sizes (at certain value intervals) of fluorescent substance.

The difference in average grain size between the fluorescent substance of the first layer 5a and the fluorescent substance of the second layer 5b is 2 microns or more. Thus, a kind of shielding layer is formed between both the layers and thereby the occurrence of blackish brown spots is greatly suppressed, premitting a fluorescent lamp free of application trouble, e.g., blackish brown spots, to be obtained.

Title: Marking method at beveling part of wafer
Inventor: OISHI HIROSHI
IPC: H01L21/304
Filed: 1997-03-11
Abstract: PROBLEM TO BE SOLVED: To determine a mark for crystal orientation easily without imparting residual strain into a wafer by polishing a predetermined position at the beveled circumferential fringe part of the water using a polishing butt wheel thereby making a thin shallow groove, as a mark for identifying the crystal orientation, in the beveled part. SOLUTION: A polishing butt wheel 1 pressed against a beveled part 3 while turning to make a thin shallow groove 4. Since a polishing butt wheel 1 is used for putting a mark, a groove 4 can be made slightly on the inside of the beveled part 3 with no loss of effective area of the wafer 2 nor any adverse effect, e.g. machining stress or thermal stress, on the wafer 2 body. Since a groove 4 thus made has different light reflecting state, it can be detected both visually and through use of an optical sensor and when the groove 4 is made on the surface side of the water 2, the water can be positioned from the surface side easily and visually or through an automatic system.

IPC: G06F9/44
Filed: 1990-03-07
Abstract: PURPOSE:To attain a fast search even if the description of the method definition is shared with objects by taking out the method definition while referencing to the method selection information on an object when the method of the object is called out at the execution of a program. CONSTITUTION:A class and a method are defined or set in a preprocessing step, and the classes forming an object to be generated are designated for the acquisition of a class list. Then the method selection information are collected from each class for the production of the method selection information on the object. An editing operation needed in an postprocessing step is carried out for the generation of an object having a prescribed internal structure. When a method is called out, the required method is checked in order to check the presence or absence of methods of the same form. Thus it is possible to prevent the increase of the program code capacity in this processing system and to select the optimum method definition in accordance with the state of a method call instruction. Then the method calling speed is increased, that is, the executing speed of an object-based program is increased.
