Title: Production of semiconductor device
Inventor: ICHINOSE YOSHITO
IPC: H01L21/322
Filed: 1980-07-09
Abstract: PURPOSE:To prevent distortion in the pulling out of a wafer by releasing gas elevating in the temperature with a gas discharging means provided at a position corresponding to a semiconductor substrate on a carrying base which is put into or out of a basket housing semiconductor substrates. CONSTITUTION:A basket 1 with a frame 1a housing a plurality of semiconductor wafers 2 is placed and a carrying base 4 to be put into or out of it is provided with a supporting rod 3 having a hollow section 6. A gas discharging hole 5 is provided to release gas elevated to a desired temperature through the hole thereby heating the semiconductor substrate up to a given temperature. This allows the pulling out of wafers without difference in the temperature of the wafers between the central and peripheral parts thereof. Thus, no distortion takes place in the pulling out of the wafers thereby eliminating deficiency and deflection of the crystal.

Title: Structure of low-temperature tank
Inventor: ASAI YUUICHIROU
IPC: F17C3/06
Filed: 1984-05-12
Abstract: PURPOSE:To use a plane steel material as a steel plate directly contacing low- temperature stored goods by forming a steel plate of an inner tank like a plane figure and fixing the steel plate to a rigid outer shell wall, with only corner portions of the inner tank bound. CONSTITUTION:If tension is generated in a steel plate 21 by a fall of temperature in an inner tank 2, as the steel plate 21 is supported by a binding anchor 6 at the corner portions thereof, the tension of the steel plate 21 is bound by the binding anchor of each side. Though the corner portions of the steel plate 21 are bound to generate tension in the steel plate 21, there is no possibility that the steel plate 21 is broken, because each steel material is less than a permissible stress value. Furthermore, as a flexible shaft 52 of a flexible anchor 5 adhering to the steel plate 21 is bent, even if the steel plate 21 is deformed, stress is not generated to concentration on the connecting portion of the steel plate 21 and the flexible anchor 5.

Title: Diversity receiver
Inventor: SUZUKI HIROHISA
IPC: H04B7/08
Filed: 1988-04-15
Abstract: PURPOSE:To prevent occurrence of new noise and deterioration in the audible sense by generating an inhibit signal from a frequency detection circuit if switching frequency of two antennas is increased thereby inhibiting the changeover of the antennas. CONSTITUTION:If simultaneous disturbance to antennas 1, 2 lasts for a long time and an output of a T-FF 19 of a noise detection circuit 15 changes for, e.g., four times during a prescribed period, then a count of a counter 22 of a frequency detection circuit 20 reaches 4 and an output signal is generated. Thus, the output signal is applied to a monostable multivibrator 24 as a trigger and the output of the monostable multivibrator 24 goes to an H level. Thus, the inhibition circuit 25 is in the inhibit state and the output is kept to L or H and independently of the output of the FF 19. The state lasts while the output of the monostable multivibrator 24 reaches H and the selecting state of the antenna 1 or 2 is kept.

Arrays of photodiodes 1 are shaded on the transparent resin film 11 to form an optical black. A difference of a dark current hence disappears over a wide range of temperature region and so a stable video signal can be obtained.

Filed: 1985-05-02
Abstract: PURPOSE:To decrease a working cost etc. by inserting a metallic die for screw formation to a blank pipe, and then, forming a screw while pressing an external periphery with a divided pressing dice. CONSTITUTION:A screw forming metallic die 2 having an external diameter slightly shorter than an internal diameter of a blank pipe is prepared, and is inserted in the blank pipe 1 in advance. While giving a press to the blank pipe 1 by means of a dice 3 divided to plurality from the external periphery, the pipe 1 is forced into a prescribed position. Then, after the dice 3 is released, the metallic die 2 for the forming is drawn out while being rotated along the screw. It this way, the screw is processed at an internal surface of a nozzle while an orifice joint 4 is formed. As there is no cutting work to be performed, the working cost is reduced, and in addition the removal and fitting of the nozzle is simplified.

Title: Electroless tin coating bath and film carrier of tab formed with tin coating film by using this coating bath
Inventor: NISHIKAWA TETSUJI
IPC: C23C18/31
Filed: 1997-03-28
Abstract: PROBLEM TO BE SOLVED: To provide an electroless tin coating bath which is high in the deposition rate of metal and good in workability and is simultaneously good in the bondability of the resulted coating film. SOLUTION: A trace amt. of a soluble salt of the metal having standard oxidation reduction potential within a range of -0.8 to +0.8 volts is compounded in a range where the tin alloy coating film is substantially not formed with the coating bath consisting of (A) a soluble salt of tin (I), (B) an acid, such as org. sulfonic acid and (C) a complexing agent. Since the specific metal soluble salt is compounded by limiting the amt. thereof to the prescribed trace amt. range, the rapidly increased film effect of the tin coating film and the good bondability are made effectively compatible. The execution of the electroless tin coating at a low temp. is, therefore, possible and the productivity is improved in addition, the effective dealing with a TAB method, etc., is possible.

Abstract: PURPOSE:To shorten the initial catch time during which a signal deviated from the nominal value is reproduced in a phase locked state, by adding a frequency control loop to a phase locked loop. CONSTITUTION:An input signal is mixed with the output signal of a VCO2, and this mixture output is supplied to a phase detector 5 forming a PLL and to an envelope curve detector 13 through a BPF4. The signal underwent the amplitude detection through the detector 13 is supplied to a phase detector 15 via a BPF14. While the sweep signal sweeping the frequency of the VCO2 is supplied to the detector 15 through the BPF14 and used as a reference signal that supplies the phase detection to the filter output of the detector 13. The detection output of the detector 15 is supplied to an adder 8 via an LPF16, a blind sector 17 and a loop filter 18 and added with the output of a sweep oscillator 7. This added output is used as an input signal of the VCO2 and forms an AFC loop. Thus it is possible to set the frequency sweeping speed of the VCO2 without having the limitation of the PLL loop band width. In such a way, the initial catch time of signals is shortened.
