Title: Heat sink with fitting pin and manufacture thereof
Inventor: OKAMOTO SABURO
IPC: H01L23/40
Filed: 1999-04-28
Abstract: PROBLEM TO BE SOLVED: To secure a heat sink onto a substrate as easily as possible and inexpensively by caulking a heat sink body in the thickness direction under a state where the end of a pin is inserted, in the direction perpendicular to the thickness direction of the heat sink body, into an insertion hole made at an arbitrary position at the end part of the heat sink body. SOLUTION: The heat sink 1 has a body 10 made of a flat metal plate of 2 mm thick, at one end thereof, with two insertion holes 11 into which fitting pins 2 are inserted from the end part 20 thereof in the direction perpendicular to the thickness direction of the body and then the inserted part 21 is secured in the thickness direction of the body. Securing part of the fitting pin 2, i.e., the end part of the heat sink body 10, has the same thickness as the body and thereby the heat sink is extremely compact. A semiconductor element 5 is then bonded to the body 10. When the fitting pins 2 are fitted in fixing holes made in a substrate, the heat sink 1 is secured onto the substrate under a state where the legs 50 of the semiconductor element 5 are connected with the circuit on the substrate.

Title: Original feeder of electronic copying machine
Inventor: KOJIMA HEIICHIROU
IPC: G03G15/00
Filed: 1981-08-04
Abstract: PURPOSE:To improve the activity of a machine by providing a couple of clamping roller and a gate member, and clamping only the front edge part of a succceeding original once a precedent original is fed to a scanning station and then automatically feeding the succeeding original to the scanning station on the scanning of the precedent original. CONSTITUTION:While a precedent original is scanned at a scanning station 2, a succeeding original is inserted through an original insertion opening and once its front edge part is stopped by a gate 10, the original is detected by a photosensor 15 to release the energizing of a solenoid 11 on the basis of the detection signal, thereby bringing a driven roller 3 and a driving roller 4 into contact to clamp the original. Once the scanning of the preceding original ends, the gate 10 is released by the scanning end signal and at the same time, the driving roller 4 is started to feed the original to the scanning station 2. After the rear end of the original passes the position of a photosensor 16, the gate 10 is closed by the signal to separate the driven roller 3 and driving roller from each other at the same time.

Title: Device for detecting approach of conductor and approach position
Inventor: KATABAMI KOICHIRO
IPC: G06F3/044
Filed: 1998-04-15
Abstract: PROBLEM TO BE SOLVED: To simplify signal processing, to improve noise resistance, and to eliminate the poor influence of floating capacity by receiving and processing an equivalent vibration current from a conductor such as a human body through capacitance coupling via a voltage vibration system. SOLUTION: When a vibration voltage generator 14 in a non-vibration system 2 generates a sinusoidal wave with a frequency of for example 460 kHz, the output allows an entire voltage vibration system 1 to be subjected to voltage vibration by the same phase and amplitude of 460 kHz via a ground circuit 11 of the voltage vibration system 1 or the power supply circuit of a power supply 12. At this time, when a finger 7 that is a conductor to be detected approaches a sensor panel 3, capacitance coupling 8 occurs between a film-shaped resistor 5 being formed on the panel 3 and the finger 7, and a vibration current (AC signal current) flows via the capacitance coupling 8. At this time, more signal current flows from a stripe-shaped electrode 6 that is placed near the tip of the finger 7 and has smaller face resistance than that of the resistor 5.  The signal current is introduced to a signal processing part 10, and the approach position of the tip of the finger 7 on the surface of the panel 3 is detected according to the level of the signal current.

Filed: 1978-10-03
Abstract: PURPOSE: To reduce noises due to the collision of a billet, by fixing a cushion material between an expanded metal plate and a punched metal plate which have a  plurality of through holes.  
     CONSTITUTION: An expanded metal plate 7 having a plurality of through holes are fixed on a support plate 2. A cushion material 6 such as a rubber sheet and a punched metal plate 4 having a plurality of through holes are fixed on the metal plate 7. When a billet 5 drops, it collides against the metal plate 4 and slides onto a conveyor 3. At that time, the dropping energy of the billet 5 is absorbed by the cushion material 6 and the vibration of the billet 5 and the metal plates 4, 7 is damped by the through holes of the metal plates. Therefore, the noises are reduced.

Title: Knocking detector
Inventor: YAMAGUCHI KIMIAKI
IPC: G01M15/00
Filed: 1979-09-24
Abstract: PURPOSE: To obtain a sufficiently large knocking detection signal, by providing an oscillator to resonate with the vibration when the engine has knocking and at the same time using a small-size coil to respond to the change of inductance caused by the resonance of the oscillator.  
     CONSTITUTION: The knocking detector 2 is mounted by the means such as the screw or the like at the cylinder block part of the 4-cylindered internal combustion ongine 1. The detector 2 incorporates the oscillator 22 which resonates with the knocking frequency of 5W10kHz. And when the tip of the oscillator 22 resonates with the knocking vibration of the engine, the gap between the tip and the core 23. As a result, the magnetic resistance of the magnetic path passing through the oscillator 22 and the core 23 varies in synchronization with the resonace. This causes a change of inductance, and thus the oscillation frequency of the oscillating circuit 25 varies. Owing to this resonance function, a knocking detection is possible with high sensitivity.

Title: Circuit for discriminating code error rate
Inventor: ENDOU TAKEMI
IPC: H04L1/24
Filed: 1982-07-14
Abstract: PURPOSE:To provide an error rate discriminating circuit having no influence of a burst code error, by connecting the 1st and 2nd pulse expanding circuits to the output of a code error detecting circuit in parallel in a digital transmission system. CONSTITUTION:The pulse expanding width T2 of a monostable multivibrator 11 to be triggered repeatedly is set up larger than the average interval time of error pulse generation. The pulse expanding width T1 of a monostable multivibrator 10 is set up larger than the sum of burst code error generation time width TB and the pulse expanding width T2 of the monostable multivibrator 11. A burst code error (i) is generated on the supposition that other error pulses are scracely generated. The Q output of the monostable multivibrator and the Q and Q' outputs of the monostable multivibrator 11 are like B, C and D in the figure. The Q output of the monostable multivibrator 10 is turned to the H level as shown in the figure B by a differential output E. Namely, the output of the monostable multivibrator 10 and the Q output of the monostable multivibrator 11 have the same time width and different L and H levels and the output (f) of an AND circuit 13 is kept at the L level as shown in the figure F. Therefore, the circuit 13 generates no output. Namely, the size of the code error rate can be discriminated without influence of a burst code error.

Abstract: PROBLEM TO BE SOLVED: To prevent cracking and fracture at a joint end of a plate material when pressing by forming a notch part at a plate material peripheral edge part having an elongation flange near the jointing end of the plate material. SOLUTION: Annular notch parts 6 and 7 are formed to plate materials 2E and 2F forming a collected blank material at the plate material peripheral edge part having an elongation flange and also near a jointing end 4 of the plate material. The peripheral edge part of the notch part 6 is formed in a manner that two or more different curvatures R1 and R2 are continued, and similarly the peripheral edge part of the notch part 7 is formed in a manner that two or more different curvatures R3 and R4 are continued. With respect to the collected blank material, for example, at a side sill part, the plate materials 2E and 2F are jointed by welding in advance, and the notch parts 6 and 7 are formed at this jointing time.  Thereby, resistance against elongation is decreased at the notch part peripheral edge, and tensile stress applied to the jointing end 4 can be reduced, so as to prevent cracking and fracture of the jointing end 4.
