Title: Jam detecting method
Inventor: IWATANI TOSHIO
IPC: G03G15/00
Filed: 1980-03-06
Abstract: PURPOSE: To accurately detect the jam of a sheet material such as a transfer paper or original in a copying machine, rotary camera or the like by providing a pluraity of detectors on a conveyor belt.  
     CONSTITUTION: A camera 1 fitted with a photographing lens 2 and loaded with a microfilm is supported by a support 3. A sheet materials 9 are placed on a mounting table 8 and successively conveyed, one by one, onto the upper surface of a belt 6 by a feed roller 11 of a feeder 10. According to the number of the sheet materials passing between the first and second detectors 20 and 22, a setting value is set, and when the original is jammed as the result of a trouble, the number of the sheet materials increases, so that the count value of a counter 30 becomes lager than the setting value. Accordingly, the driving system is stopped by the jam detecting signal from a decoder 31, in order to prevent the breakage of the sheet material and the damage to the apparatus.

Title: Method for correcting error of storage device
Inventor: NAKAGAWA NOBUO
IPC: G06F12/16
Filed: 1983-02-23
Abstract: PURPOSE:To improve the reliability of a storage device of a standby duplicated structure system by supplying temporarily power to a memory section of the standby system only to an address where an error occurs as to a logical inverting error being a part of an operating system memory section and using the output data of the memory section of the operating system after being replaced with an output data of the memory section of the standby system. CONSTITUTION:The system is so designed that the output data of memory sections 2a, 2b storing a program and a constant is selected by memory changeover circuits 17a, 17b. Then, if a parity error occurs in the designated address of the memory section 2a of the operating system, for example, the selection of the memory changeover circuit 17a is switched to the memory section 2b by the control of a memory control circuit 19a only at the memory read of the designated address, the error data of the memory section 2a is corrected into the data of the memory section 2b and transmitted to a central processing unit as the output data of the storage device 1a. Thus, the reliability is improved only with the addition of simple error detecting circuit sections 3a, 3b by correcting the output data by the memory of the standby system only for the designated address, when a parity error occurs in the designated address of the memory section of the operating system in this way.

Title: Distance measuring equipment
Inventor: KAYAMA YASUNAGA
IPC: G01S7/48
Filed: 1994-02-01
Abstract: PURPOSE:To provide a distance measuring equipment in which high speed signal processing is realized while avoiding increase in the scale of signal processing circuit by reducing the signal processing load at a light receiving means and subsequent circuit. CONSTITUTION:The light receiving range is split in same direction as the splitting direction of light transmitting range with the border of split light receiving range being shifted from that of the split light transmitting range. Light is then emitted in a predetermined order from three LD elements 1a-1c in a semiconductor laser 1 and a distance detecting section detects the distance up to an object based on the time being elapsed after emission of light from the LD elements 1a-1c before reception thereof by light receiving elements 4a-4d. A direction detecting section then detects the direction of the object based on the decision results at a transmitting light range deciding section and a receiving light range deciding section. Consequently, a measuring effect similar to that, obtained by dividing the measuring range finely using many light receiving or emitting elements, can be achieved through combination of fewer pieces of information.

Filed: 1990-02-07
Abstract: PURPOSE:To prevent a failure from being generated in mold plates by a method wherein a lead frame, on which a semiconductor element is previously bonded, is pinched by the two mold plates at the time of a clamping, the element is sealed by encapsulating a resin in both mold plates and the resin sealing the element is pressed by enjector pins at the time of a mold opening and is separat ed from the mold plates. CONSTITUTION:A lead frame, on which a semiconductor element is bonded previously, is pinched by two mold plates 2 and 3 at the time of a clamping, the element is sealed by encapsulating a resin in cavities 4 and 5 of both of these plates 2 and 3 and after then, a sealing resin 6a sealing the element and a cull part resin 6b are pressed by ejector pins 7 and 8 at the time of a mold opening and are made to separate from the plate 2. Accordingly, as the bite of the pins 7 and 8 into the resin can be stopped, the pins 7 and 8 can be made to separate reliably from the resin at the time of the mold opening and a resin residue on a gate part and a package break can be prevented from being gener ated between both mold plates after the mold openings.

Title: Manufacture of field-effect transistor
Inventor: KATOU NAOKI
IPC: H01L29/417
Filed: 1981-03-03
Abstract: PURPOSE:To shorten a distance between a source and a gate by selectively changing a negative resist on the surface of a source-drain electrode into negative by utilizing the high reflection factor of the electron rays or a source-drain electrode material and evaporating a gate electrode material while using the resist as a mask. CONSTITUTION:An active layer 2 and the source-drain electrode 3 are formed onto a GaAs sbustrate 1 in normal size, and an insulaing film 4, such as a silicon nitride film, an oxide film, etc. is shaped to sections except the electrode 3 in order to form the contrast of the reflection factor. The negative type electron beam resist 5 is applied, and electron beams are irradiated. The quantity of exposure is increased because the surface of the electrode 3 has the high reflection factor of electrons. The lateral direction of the electrode 3 is also exposed because the direction of reflection of electrons is approximately isotropic. Accordingly, the resist 5 is changed into negative in a shape that has eaves. When the insulating film 4 is removed and the gate electrode material 6 is evaporated, a gate electrode 6' is formed in a self-alignment shape, and the field- effect transistor having a small distance between the gate and the source is obtained.

Title: Low frequency displacement device
Inventor: ORIMO TATSUYA
IPC: H04N19/189
Filed: 1990-02-09
Abstract: PURPOSE:To obtain a satisfactory picture quality by detecting a noise quantity in the low frequency of a multiplex sub-sample transmission signal in a noise detection means and changing a displacement rate between a decoding signal and respective low frequencies of the multiplex sub-sample transmission signal in accordance with the noise quantity in a displacement variable means. CONSTITUTION:The noise detection part 7 generates a control signal as against a variable coefficient unit 4. The inputted multiplex sub-sample transmission signal is given to the noise detection part 7 and it detects the noise quantity of the transmission signal. It outputs a smaller coefficient as the noise quantity increases much more, and outputs the larger coefficient as the noise quantity decreases. Namely, the rate of displacement by the inputted multiplex sub-sample transmission signal is reduced and the rate of a decoding signal is improved as the noise quantity increases much more. Since the rate of displacement is deteriorated when the quantity of noise components is much, the picture quality based on a low frequency displacement signal can be maintained in a satisfactory state even if the noise components of the low frequency is included in the transmission signal.
