Patent JP-S60149140-A (JP)
Title: Bonding apparatus for assembling of semiconductor device
Inventor: SAKURAI MINORU
IPC: H01L21/58
Filed: 1984-04-11
Abstract: PURPOSE:To prevent a lead frame from adverse thermal effects by rapidly lowering a heat block when encountering some trouble such as failure of the assembling machine. CONSTITUTION:A beltlike lead frame 1 is fed successively over a guide rail 2 and a heat block 3 to be assembled with a bonding mechanism B. During normal operation, a bar 11 is in its lowered position and the upper face of the heat block is maintained at the same level with that of the guide rail. In case of some trouble, a stop switch is operated so as to raise the bar 11 while lowering a strut 9, whereby the upper face of the heat block becomes lower than that of the guide rail. A gap is thereby defined between the lead frame 1 and the heat block 3 and the temperature of the lead frame is decreased rapidly. By maintaining the temperature of the lead frame at 200 deg.C or less, the lead frame can be substantially prevented from adverse thermal effects such as oxidization or annealing.

IPC: H04N5/335
Filed: 1980-05-28
Abstract: PURPOSE:To use a sensor provided with an adequate required number of photoelectric conversion elements, by dividing a scanning circuit, controlling an image sensor, into groups in series and by selectively supplying a gate pulse to a required group. CONSTITUTION:A scanning circuit SC controlling a photosensitive element array PDA of photodiodes and a switching element array SWA of MOS transistors (TR) are divided into (n) groups SC1-SCn, which are connected in series. Each gate of control MOS TRs Qa1, Qa3- of the circuits SC1-SCn are connected to input terminals 41-4n for gate pulses respectively. When all of terminals 41-4n are at low levels, all of TRs Qa1, Qa3- are made into off state and pulses V1- are supplied. For example, when only the terminal 41 is applied with a low-level pulse, the control MOS TRs following the circuit SC2 all turn on and only the circuit SC1 supplies pulses V1-.

Title: Constant-amplitude oscillator
Inventor: ANDOU TAKASHI
IPC: H03B5/30
Filed: 1980-05-27
Abstract: PURPOSE:To vary and set the oscillation frequency of an oscillator and to hold the set amplitude constant, by controlling the conduction period of a switching element by driving the oscillator by using the switching elememt. CONSTITUTION:If a current flows through the driving coil 3 of an oscillation part 1 owing to a shock, noise, etc., in feeding electric power, an oscillator 2 oscillates and its oscillation is detected by an oscillation detecting coil 5, increasing its phase current again through amplifying circuits 11 and 14. In this case, the output amplitude of the oscillation part 1 is less than a set value, and consequently the outpt C  of a comparing amplifier 8 increases above a saw-tooth wave voltage D. Then, a  comparator 13 generates no output and the circuit 14 operates as a mere amplifying  circuit. As the oscillation amplitude increases, the output amplitude of the oscillation part 1 increases a comparator B controls the circuit 14 with an output E to generate the period when an output F is a (0).

Title: Detection switch
Inventor: TANIGUCHI MICHIAKI
IPC: H01H36/00
Filed: 1996-02-29
Abstract: PROBLEM TO BE SOLVED: To allow a user to easily recognize a margin in use being a difference between an adjusted threshold level and the output of a detection circuit by using a threshold level adjustment type detector switch. SOLUTION: A CPU 4 has functions of a comparator means 4 comparing output from an A/D converter 3 with a prescribed threshold level and a threshold level adjustment means 4b adjusting a threshold level of the comparator means 4a. A comparison output of the comparator means 4a is outputted externally via an output circuit 5 as an object detection signal. An operation section 6 inputs entry of an operation mode and of automatic sensitivity setting, up/ down input to manually increase/decrease a threshold level, and an off-point threshold level at which an output is cleared after an object is once sensed to the CPU 4. To the CPU 4, a margin output circuit 7 is connected, which outputs a difference between a threshold level set by a threshold level adjustment means 4b and an output level at present from the A/D converter 3 as a margin.  Since the margin is recognized by the user at mounting or at sensitivity setting of the like, a proper mount position is selected.

Abstract: PROBLEM TO BE SOLVED: To prevent spilling of rice grains when rice grains are washed by putting a semicircular lid with net on one end of a pan in a rice cooker and fixing it on the pan in the rice cooker by rubber attached to the lid with net. SOLUTION: A lid with net 2 having the same semicircular shape as a circumferential curve of a pan 1 in a rice cooker is mounted on the pan 1 in the rice cooker by rubber 3. Rubber 4 is attached to an inner curve of the lid with net 2 to make adhesion face with the pan 1 in the rice cooker close. A fixing plate 5 is fitted along outer periphery of the lid with net 2, and recessed sections 6 for hooking rubber 3 are formed at both ends of the fixed plate 5. When it is used, the lid with net 2 is put on one end of the pan 1 in the rice cooker, the rubber 3 is put on the recessed sections 6, and the rubber 3 is hooked in the recessed sections 6 and is fixed. Rice grains are washed as it is, and there is not possibility that rice grains are spilled because rice grains are shut off by the net even if water is thrown away.  Consequently, it is possible to throw away washing water of rice grains completely and quickly without worrying about spilling of rice grains.
