Title: Semiconductor wafer plating jig
Inventor: EZAWA HIROKAZU
IPC: C25D5/02
Filed: 1991-04-22
Abstract: PURPOSE:To stably plate semiconductor wafers for a long time by providing a cathode contact on the surface of the semiconductor wafer, which is sealed with a seal member and is not brought into contact with plating liquid, to prevent the plating liquid from being deposited in the front end part of the cathode contact. CONSTITUTION:A semiconductor wafer 1 is held by holding members 3 and 4 and is immersed in the plating liquid and is plated. A seal member 5 is arranged on these holding members 3 and 4 so that the plating liquid does not flow to parts other than the face to be plated of the semiconductor wafer 1. A cathode contact 7 connected to a cathode wiring 11 is provided in a resist peeled part 6 in the end face part, of the sealed semiconductor wafer 1. Thus, the cathode contact 7 is not brought into contact with the plating liquid, and semiconductor wafers are stably plated without deterioration for a long time.

IPC: H01L31/10
Filed: 1994-05-31
Abstract: PURPOSE:To measure the spectral distribution of incident light by fetching a photoelectric current near p-n junctions formed at different depths in one semiconductor substrate. CONSTITUTION:After an n-type annular area 21 is formed by diffusing an impurity from the surface of a p-type silicon substrate 11, a p-type silicon layer 12 is epitaxially grown. Then, an angular ring-like n-type area 22 which is smaller than the n-area 21 is formed by diffusing an impurity from the surface of the silicon layer 12, an n-type connecting layer 71 which surrounds the area 22 and reaches the outer periphery of the area 21 is formed. Thereafter, an angular ring-like n-type area 23 and n-type connecting layers 72 and 73 are formed by using the same method.

Title: Ignition timing controller for internal combustion engine
Inventor: NAGANO MASAMI
IPC: F02P5/15
Filed: 1986-05-23
Abstract: PURPOSE:To control torque in a direction lessening rotational fluctuations as well as to prevent a shock at the time of acceleration and jerky driving from occurring, by detecting an engine being in an accelerated state and, if this accelerated state is the case, controlling ignition timing based on a variation in engine speed and its direction. CONSTITUTION:Only at the time of acceleration, the specified ignition timing control is operated by a control unit 15 as long as the preset time. Control over this ignition timing takes place in the following process that a variation in engine speed to be detected by a crank angle sensor of a distributor 16 is detected by a differential value dN/dt, a compensating quantity is determined by size of dN, and compensation for timing advance and delay is carried out to a map retrieval value for the ignition timing with a sign of the dN/dt. That is to say, when the sign is positive, the compensation value is more retarded than the map retrieval value for the ignition timing, and when it is negative, the compensation value is advanced. Therefore, when the engine speed is low, its torque is increased, but when it goes up, the torque is decreased, thus a variation in the engine speed, namely, a shock at the time of acceleration and jerky driving are all preventable.

Title: Ultrasonic body detector
Inventor: YAMANE TOSHIKI
IPC: G08B13/16
Filed: 1988-05-14
Abstract: PURPOSE:To eliminate misdetection due to mutual interference by making the sum of the increased transmission time interval of one ultrasonic body detector and the decreased transmission time interval of the other detector different by longer than the transmission gate time of the ultrasonic body detectors. CONSTITUTION:When the two ultrasonic body detectors are used under the conditions wherein mutual ultrasonic wave pulses are received, the transmission time intervals of the ultrasonic body detectors are updated every time an ultrasonic pulse (a) is sent out. Namely, the time intervals are determined according to various conditions such as the pulse width of the ultrasonic pulse (c), a reception gate (d), and the installation environment of the ultrasonic body detectors. Then the transmission time interval of one ultrasonic body detector at a certain point of time is set to a value which is larger than the last time interval by a half as large as the transmission gate time Td. Consequently, even when the two ultrasonic body detectors are used while receiving their mutual ultrasonic pulses, misdetection caused by their mutual interference is eliminated.

IPC: G11B5/027
Filed: 1978-09-27
Abstract: PURPOSE: To prevent an error adjustment due to malfunction by activating a control circuit which performs the automatic compensation of a recording system by recording and reproducing reference signals only when test, recording and reproduction switches are all operated.  
     CONSTITUTION: When reference signals are recorded and subsequently reproduced, the automatic compensating adjustment of a recording system is made by a reproduction output passing through holding circuit 10, A/D converter 11, arithmetic circuit 12, etc. Those circuits 10W12 and reference signal oscillator 13 are controlled by control circuit 14, which is activated with test-switch closing signal recording and reproduction switches 16 and 17 both closed only when recording and reproduction mode signals outputted by memories 18 and 19 are AND-ed by AND gate 20. Therefore, only when the recording switch and reproduction switch are both closed, closing a test switch makes the automatic compensating adjustment, thereby preventing an error adjustment due to malfunction.

IPC: C02F3/00
Filed: 1977-09-30
Abstract: PURPOSE: To provide a sanitary waste pruification apparatus which facilitates pruification  tank with such an arrangement that a part of a sanitary water in a sedimentation tank is returned to a dilution tank.  
     CONSTITUTION: A sanitary waste flowing into a separation tank 4 from a stool 1 undergoes solid/liquid separation. The sanitary waste thus treated is introduced into a dilution tank 100 to be diluted with an intermediate water from a sedimentation tank 7 and fed into an aeration tank 6 for treatment. Then, the sanitary waste water after the treatment in the tank 6 is fed into the tank 7 to deposit suspended matters and discharged out through a disinfecting chamber 9 for disinfection. Here in this process, compressed air is fed to a returning pipe 8 through an air pipe 5. The resulting air lift effect makes the intermediate water purified in the tank 7 to return to the tank 100 continuously. With a proper adjustment of a valve 52, the amount of the intermediate water returning to the tank 100 is so controlled as to be enough to dilute the high concentration sanitary water flowing into the tank 100 through a passage 22. The intermediate water returning to the tank 100 is only a part of the water flowing into a purification apparatus 2, therefore, the amount thereof does not exceed the total amount of flash water and the like from the stool 1, and the apparatus 2 can be designed in the same volume as that of conventional ones

Title: Tape drive controller of tape recorder
Inventor: KUMAGAI TAKUYA
IPC: B65H59/38
Filed: 1979-09-14
Abstract: PURPOSE: To control a tape speed and tension securely and easily even in high-speed tape running state by detecting the driving current of a take-up reel motor and by controlling the servo circuit of a supply reel motor by the output of the detection.  
     CONSTITUTION: As the driving current of reel motor 1 varies with the load of the tape path system, the voltage across resistor 6 that detects the driving current of reel motor 1 varies and is compared to a reference voltage by voltage comparator 8, etc. Voltage comparator 8 decreases in output level when the detected voltage is greater than the reference voltage and increases when not. Therefore, as fluctuations of the load increase the driving current of reel motor 1, its rotating force also increases, but the back tension of reel motor 2 decreases to the contrary. Thus, constant rotating force torque is held and the constant speed of the take-up reel turntable can be attained. This constitution can exercise control over the tape speed and tension easily and securely even in high-speed tape run mode.
