Title: Manufacture of semiconductor pellet
Inventor: SUYAMA NAOMI
IPC: H01L21/316
Filed: 1980-11-29
Abstract: PURPOSE:To obtain semiconductor pellets having the favorable external appearance and having stable characteristic by a method wherein a flexible protective material is filled up between the pellets arranged in order at the prescribed interval, and the protective material is cut after it is cooled to be hardened. CONSTITUTION:A nozzle 13 is arranged in front of a cutter 12 being made to face to the rubber material 3, cooling gas 14 of N2, etc., is made to be blasted off to cool the rubber material speedily, and the rubber material is cut with the cutter 12. Rubber loses flexibility and adhesion, and positioning of the wafer is ensured, the wafer does not move, the rubber material is not adhered to the cutter, and cutting is facilitated. Moreover when tension is applied to a sheet 10 in the direction shown with arrow marks, rubber can be cut easily by shallow cutting with the cutter 12 as to split off by itself. By this constitution, because the rubber material is cut after it is hardened, the rubber material does not curve when cutting is to be performed, a crack or peeling off is not generated, and the wafer can be cut to be divided into the pellets having the favorable exteranl appearance and having stable characteristic.

Title: Wiring forming method
Inventor: SATO JUNICHI
IPC: H01L21/3205
Filed: 1989-06-30
Abstract: PURPOSE:To sensitively detect the end point of etching-back and improve reliability, by performing etching-back with mixed gas of non-carbon based fluoride gas and oxidizing gas, and detecting the end point of etching-back by monitoring the emission spectrum of carbon monoxide. CONSTITUTION:As the result of preliminary experiment, the sharp detection of an end point is enabled by etching-back with mixed gas of SF6 and O2, and this system is practically applied to base body. Silicon oxide is used for the material of an interlayer insulating film 5; tungsten is used for conducting material 8. When etching-back is performed for the above base body under the same condition as the preliminary experiment, and the peak intensity of emission spectrum of carbon monoxide is monitored, the peak intensity rapidly decreases at the time point when the surface of the interlayer insulating film 5 is exposed, and the end point can be sharply confirmed. Of course, the surface of the base body is turned into an excellently flattened state.

Title: Electric field type human body detector
Inventor: TAKADA YUUJI
IPC: G08B13/26
Filed: 1980-11-28
Abstract: PURPOSE:To eliminate the possibility of causing false announcing occuring due to  higher harmonic noises caused synchronously with an electric power source completely  by so arranging a titled detector that the frequency of the detection signal emitted  from an exciting line is matched always to the integer times of the AC power source frequency. CONSTITUTION:The searching signal from a voltage control oscillator 1a is dropped  down to an electric power source frequency which is a reference by a frequency divider 1b, and is applied as a reference signal to a phase comparator 1c. Now when a  fluctuation occurs in an AC power source frequency, a deviation is produced between  the AC power source frequency and the frequency of the reference signal which is the  output of the frequency divider 1b. A comparator 1c detects this, feeds the control signal of the oscillator 1a, and outputs the detection signal of the frequency integer times  the fluctuated AC power source frequency from the oscillator 1a. Then, in case when a  fluctuation occurs in the AC power source frequency, the frequency of the detection signal is always equal to integer times of the AC power source frequency, that is,  the frequency of any of the higher harmonic noise of the power source, whereby the  generation of a beat between the detection signal and the higher harmonic noise is perfectly prevented.

Title: Inclination sensor with preventing device for malfunction due to vibration
Inventor: USUI YOSHIKAZU
IPC: G01C9/18
Filed: 1986-07-18
Abstract: PURPOSE:To stops a power source and to prevent a human-body catching accident, etc., from occurring by allowing a sensor to sense that a motor cycle, etc., is turned over in such a case and turning off an electric system. CONSTITUTION:A sensor A cuts an error signal due to vibration by the combination of a switch composed of conductive liquid 2', electrodes 4' and 5', and a storage container 1', and a timer part 6 and sends out a signal when a set angle is reached. A sensor part B has a separator 3 provided between conductive liquid 2 and electrodes 4 and 5 and cuts an error signal due to vibration. Consequently, even if the liquid 2 contacts the electrodes 4 and 5 owing to vibration, a contacting signal is prevented from being outputted. Further, when the container 1 is fallen down, the liquid 2 passes through the gap between the container 1 and separator 3 to short-circuit the electrodes 4 and 5, so that a signal is accurately outputted. Further, if the liquid 2' vibrates in the container 1' to contact the upper electrodes 4' and 5', outputs of the electrodes 4' and 5' are inputted to the timer part 6 and only a short-circuit signal longer than a timer set here is transmitted to a contacting output part 7 and a noncontacting output part 8 to prevent an error signal from being generated, thereby outputting a falling-down signal.

Title: Semiconductor memory
Inventor: UCHIDA YUKIMASA
IPC: G11C11/413
Filed: 1983-09-16
Abstract: PURPOSE:To eliminate the power loss of a back-up power supply through an external power supply line by using a working power supply pad and a back-up power supply pad and supplying power to a memory cell through a power supply line for memory cell connected to both pads via a rectifying element respectively. CONSTITUTION:The different actions are carried out between a period T1 when the potential V1 of a working power supply line 36 is larger than the potential V2 of a back-up power supply 23 and a period T2 when the V1 is smaller than the V2. For instance, it is supposed that an external working power supply 37 is changed to an ON from an OFF before a time point t1. Therefore V1<V2 is satisfied before a time point t2 when V1=V2 is satisfied. Thus a diode 41 is off, and the memory holding current of a memory cell in a memory cell array 24 is supplied through a diode 40. When V1>V2 is satisfied, the diodes 41 and 40 are automatically turned on and off respectively. Thus the memory holding current is supplied from an externally operating power supply 37. Then the memory holding current of the memory cell is supplied from both power supplies 37 and 23.
