Patent JP-S5968891-A (JP)
Title: Semiconductor memory
Inventor: FURUYAMA TOORU
IPC: G11C11/417
Filed: 1982-10-12
Abstract: PURPOSE:To offer a static type semiconductor memory strong in a software error by impressing a voltage higher than that of a power supply voltage to a memory cell with a boosting circuit of on-chip when a power supply voltage impressed externally with a battery backup is decreased less than that at normal operation to increase the amount of charge at a storage node. CONSTITUTION:Taking the output amplitude of an oscillator 11 as Vcc, its frequency as (f), capacitance of a capacitor as C, and node parasitic capacitance between power supplies Vcc and V'cc as Cp, then the V'cc is increased idealistically to a value of V'ccmax=Vcc-2VT+(C/C+Cp) Vcc, independently of the frequency (f). Suppose that the Cp is sufficiently smaller than the C, said Formula becomes V'ccmax=2(Vcc-VT), where the VT is the threshold voltage of MOS transistors 8, 9, and the Vcc=2.5V and the VT=0.5V, are taken to obtain V'ccmax=4V, and on the other hand, Vcc=3V, is taken to obtain Vccmax=5V, and the same voltage as the Vcc at the normal operator is obtained.

Title: Method for controlling wedge of hot rolled stock
Inventor: YAHIRO AKITO
IPC: B21B37/00
Filed: 1997-06-18
Abstract: PROBLEM TO BE SOLVED: To surely control a wedge on the outlet side of a finishing mill and camber on the outlet side of a roughing mill at the time of hot rolling within an allowable range. SOLUTION: In the case that the amount of a wedge on the outlet side of a finishing mill exceeds a predetermined threshold value or in the case that the amount of camber on the outlet side of a roughing mill exceeds a predetermined threshold value, the controlled amount of a roll gap which is enough to dissolve at least the amount which exceeds the threshold value of the amount of the wedge on the outlet side of the finishing mill is obtained from the relationship between the controlled amount of the roll gap and the variation of the wedge which are predetermined in accordance with thickness, width and a material.  The amount of camber on the outlet side of the roughing mill is predicted based on this amount and by controlling the amount of leveling in the roughing mill so that the predicted amount of camber does not exceed the predetermined threshold value, the both wedge and camber are surely controlled within an allowable range without respectively taking the various factors of the generation of the wedge into consideration.

Title: Latent heat recovery heat exchanger
Inventor: KOMUKAI SHIGERU
IPC: F28F19/04
Filed: 1999-06-25
Abstract: PROBLEM TO BE SOLVED: To eliminate a water leakage accident, if any, at a heat transfer tube placed in a severe corrosion environment exposed with a dry corrosion due to an exhaust gas acid component and a wet corrosion due to an acid drain in a combustion equipment having a latent heat recovery heat exchanger. SOLUTION: A combustion equipment having the latent heat recovery heat exchanger uses a stainless steel having excellent corrosion resistance as a manufacturing material instead of a heat transfer tube 11 heretofore made of aluminum, and covers an inner surface of the tube 11 with a coating 14 of a film of a water insoluble polymer material having a thermal expansion coefficient near that of the stainless steel on an inner surface of the tube 11. Thus, even if a pinhole or a hair crack exists or takes place, this can be sealed by the coating 14, thereby entirely eliminating an anxiety of a water leakage.

Each time the projection 9a is passed across the sensor 12, the sensor 12 outputs a signal indicating this. A timer 13 measures the time difference between a driving signal for a carriage motor 11 and the signal outputted from the sensor 12, and a calculating circuit 14 calculates a deviation correction quantity for a printing-starting position from the result of measurement by the timer 13. A controlling circuit 15 controls a printing head driving circuit 16 to control a driving timing for a printing head in accordance with the deviation correction quantity thus obtained.
