Patent JP-H04196130-A (JP)
Title: Manufacture of semiconductor element
Inventor: ABE KOJI
IPC: H01L29/73
Filed: 1990-11-26
Abstract: PURPOSE:To regenerate a product whose current-amplification factor is higher than a target value into a good product without increasing the number of processes by a method wherein, at a semiconductor element by a three-layer structure, a nitride film whose refractive index has been adjusted according to a measured current- amplification factor is applied after three layers have been formed. CONSTITUTION:A base diffusion operation and an emitter diffusion operation are performed to an n-type Si wafer 1; after that, a current-amplification factor (hFE) is measured. Then, an Si3N4 film is applied onto the wafer 1 by a CVD method at about 900 deg.C by using SiH4 and NH3. Regarding a lot whose hFE exceeds a prescribed value, the mixture ratio of SiH4 is made higher than that in conventional cases the Si3N4 film whose refractive index is higher than that in conventional cases is applied, the hFE is lowered and the lot is changed to good products. Consequently, even when the hFE exceeds the prescribed value, the lot can be changed to the good products. As a result, the ratio of good products is enhanced. Regarding a lot whose hFE does not reach the prescribed value, the mixture ratio of NH3 is made higher than that in conventional case and the Si3N4 film whose refractive index is lower than that in conventional cases is applied. Thereby, the hFE is made high and the lot can be changed to good products without performing the emitter diffusion operation again.

Title: Tape cartridge
Inventor: MIZUTANI HIKARI
IPC: G11B23/28
Filed: 1989-12-11
Abstract: PURPOSE:To prevent trouble to erroneously erase recorded contents by forming first and second operation grooves at an interval between the main wall of an erroneous erasing preventing valve and the inside of an erroneous erasing preventing hole so as to execute the switching operation of the erroneous erasing preventing valve. CONSTITUTION:First and second operation grooves 26 and 27 are respectively formed at the interval between a main wall 15 of an erroneous erasing preventing valve 12 and the inside of an erroneous erasing preventing hole 15 so as to execute the switching operation of the erroneous erasing preventing valve 12. Therefore, while securing the outer surface of the main wall 15 and the outer surface of a rear wall 10b to be formed on the same surface, the switching operation can be executed. Fur ther, since the second operation groove 27 to be formed on the unrecordable position side in an erroneous erasing preventing hole 11 is set smaller than the first operation groove 26 to be formed on the recordable position side, the trouble can be prevented so that the important recorded contents can not be erroneously erased since the switching operation to the recordable position can not be easily executed. Further-more, since the first and second operation grooves 26 and 27 are set in various shapes, it can be easily confirmed whether the erroneous erasing preventing valve 12 is set at the recordable position or the unrecordable position.

Title: Semiconductor device having testing circuit
Inventor: IWAMOTO YASUNORI
IPC: G01R31/28
Filed: 1993-12-21
Abstract: PURPOSE:To provide a semiconductor device in which a self-testing function is built without increasing the number of terminals and which have excellent productivity and a circuit for testing. CONSTITUTION:High voltage Vdiag as a testing order signal is supplied to a diagnosis output terminal 4. In the case the supplied high voltage Vdiag is within a prescribed range, a testing function starting circuit 10 sends out a test starting signal TS. Corresponding to the test starting signal TS, a demultiplexer 9 connects an input terminal 1 to a test signal input terminal TEST of a control circuit 6. Consequently, determination results of a self-testing circuit built in the control circuit 6 can be known by monitoring the signals which correspond to the test signals inputted from an input terminal 1 and are outputted from an output terminal 3.

Title: Output circuit of comparator
Inventor: TSURUTA KAZUHISA
IPC: H03K19/0175
Filed: 1998-11-12
Abstract: PROBLEM TO BE SOLVED: To provide output circuit of an comparator which can prevent an integrated circuit including the comparator output circuit from decreasing in sensitivity and oscillating. SOLUTION: When a signal F1 of a terminal t1 is at H, a transistor (TR) Q3 is turned on to allow a constant current Id to flow from a power source Vcc1 to a resistance R4 via a constant current source 1, a rise in the base potential of a TR Q4 is turned on the TR Q4 to allow a current Io to flow into a resistance R5, and when the output signal of a terminal t2 goes down to L and the signal F1 of the terminal T1 is at L, the TR Q3 is turned off to make currents flow into diodes D1 and D2; and a drop in the base potential of the TR Q4 turns off the TR Q4 and no current flows to the resistance R5, so that the output signal F0 of the terminal t2 becomes H. Consequently, the constant current Id continues to flow into the output circuit irrespective of whether the TR Q3 is on or off, and the applied voltage of a circuit connected to the power source Vcc1 in the integrated circuit will not vary with the internal impedance of the power source Vcc1, thereby preventing oscillation and decrease in sensitivity owing to the sneak path of signals in the integrated circuit.

Title: Vibration-type pressure measuring apparatus
Inventor: IKEDA KYOICHI
IPC: H01L29/84
Filed: 1998-11-13
Abstract: PROBLEM TO BE SOLVED: To obtain a vibration-type pressure measuring apparatus which does not require consideration on taking measures against a resonance frequency, which can obtain a wide degree of freedom of a design and whose measuring accuracy can be enhanced by a method wherein a gel body which is formed on a measuring diaphragm is provided in such a way that the resonance frequency of the measuring diaphragm does not exist within the change range of the resonance frequency. SOLUTION: A measuring pressure is applied to a measuring diaphragm 2, and the strain of the measuring diaphragm 2 is changed. Then, the resonance frequency of a vibration beam 4 is changed. When the resonance frequency of the measuring diaphragm 2 exists within the change range of the resonance frequency, the energy of the vibration beam 4 is robbed by the resonance of the measuring diaphragm 2. The operation of the vibration beam 4 is changed into a composite vibration mode from a single vibration mode. As a result, the factor of the frequency/strain is changed, the nonlinearity of the frequency/ pressure characteristic appears, or the vibration of the vibration beam 4 is stopped. However, when the surface of the measuring diaphragm 2 is coated with a gel body 31, the resonance of the measuring diaphragm 2 is suppressed.

Filed: 1992-12-03
Abstract: PURPOSE:To improve durability, to improve the balance of a rotation, and simultaneously, to prevent the generation of vibration noise by providing a control member controlling the backward and forward actions of a back stopper by receiving the moving force from an ejecting plate. CONSTITUTION:The direction of the energizing force of an ejecting spring 58 is changed so that energizing force is not transmitted to a gear group such as a warm gear 42, a helical gear 41 and a power gear 20 and the rack 5a of a mode plate 5 when a rotable ejecting link 56 is at the completion position of an ejecting action in a loading control part. Consequently, even when the gear group 42, 41 and 20 and the rack 5a are made of a member which is easily deformed such as plastic, the deformation is prevented and the durability of the member is improved. Thus, the transmission port 2 of driving force from a motor 40 for moving to a mode plate 5 is eliminated and the generation of abnormal sound due to the inadequate meshing of gears is prevented.
