Patent JP-H09318653-A (JP)
Title: Semiconductor sensor and its output adjusting method
Inventor: YAMAMOTO MASAHIRO
IPC: G01D3/036
Filed: 1996-05-28
Abstract: PROBLEM TO BE SOLVED: To provide a high-precision semiconductor sensor capable of shortening its output rise time in design by adjusting the offset of a sensor section with an offset adjustment section. SOLUTION: The sensitivity of a semiconductor acceleration sensor is determined by the piezo resistance coefficient of the silicone forming a sensor chip, and the resistance coefficient has a positive temperature characteristic. An amplification factor of an amplifying circuit constituted of an arithmetic amplifier 47 for a temperature compensation of sensitivity has a negative temperature characteristic. If an output voltage of the arithmetic amplifier 43 at the ordinary temperature is the same at the operating lower limit temperature (referred to as low temperature hereafter) and at the operating upper limit temperature (referred to as high temperature hereafter), the output rise time after the power feed to the semiconductor acceleration sensor is started becomes long at the high temperature and short at the low temperature.  When an offset adjusting resistor 31 is trimmed to adjust the output voltage of the arithmetic amplifier 43 at the ordinary temperature, the output rise time at the high temperature can be shortened.

Title: Method for welding power tube member for transmission
Inventor: KINOSHITA TOSHIMITSU
IPC: H01J9/14
Filed: 1984-06-28
Abstract: PURPOSE:To obtain a power tube member with sufficient mechanical strength by greatly reducing the volume of a recrystallized weakened area developing between linear members during spot welding by applying a voltage with a trapezoidal waveform (on a coordinate where the horizontal axis represents time and the vertical axis represents voltage) to a welding electrode. CONSTITUTION:A voltage with a trapezoidal waveform is applied to a welding electrode for a very short time (ex., for 1ms) in order to prevent recrystallization of tungsten. Even when recrystallization of tungsten occurs during welding, a part 7a of recrystallized tungsten is discharged outside the welded area because the welding is completed in a very short time. Therefore it is possible to greatly reduce the volume of a recrystallized area 8 which is formed between linear members 6a and 6b by spot welding. When welding is completed in such a short time, thermal strain generally remains in the linear members 6a and 6b with high possibility. In this invention, however, since voltage increase and voltage decrease take place during welding, it is possible to fully avoid development of thermal strain.

Filed: 1987-05-29
Abstract: PURPOSE:To improve the entire charge/discharge current drive capability by using plural sense amplifier circuits connected to a 2nd bit line pair so as to amplify a potential difference caused in the 2nd bit line pair. CONSTITUTION:A potential difference between a 1st bit line pair 8 being an object of selection and the 2nd bit line pair 7 is amplified by a sense amplifier circuit 3 being an object of selection and plural sense amplifier circuits 22 being not an object of selection. Thus, the charging/discharging current is not concentrated onto each one of charging/discharging lines 1, 2 and even when the current drive capability of the sense amplifier circuit 3 of one selection object cannot be obtained sufficiently by a problem of a layout area, the circuit is used as a charging/discharging circuit drive section. Moreover, even when the current drive capability of a 3rd switch elements 5, 6 being an object of selection cannot be sufficiently obtained because of a problem of layout area, plural sense amplifier circuits 3, 16 are operated in parallel via a 2nd bit line 7. Thus, the entire charging/discharging current drive capability is increased.

Title: Apparatus for emboss processing of foil, use method thereof, production method thereof and operation method of apparatus
Inventor: CHARLES BOGURI
IPC: B31F1/07
Filed: 1999-05-17
Abstract: PROBLEM TO BE SOLVED: To optimally apply embossing processing to any kind of foil by making a pair of rollers mutually and relatively movable and providing operation stages mutually movable to the predetermined engaging positions of the tooth parts of the rollers in order to enable self-stabilizing operation. SOLUTION: The tip parts of the teeth of both emboss processing rollers are made flat and teeth are made short by ΔA of which the value is set to at least 2% of the height of teeth. In order to make the rollers mutually movable to a position having stability, the rollers are made mutually movable with a relative axial play at least half, pref., 3/4 the tooth pitch of the rollers. The flanks of teeth come into contact with each other to generate mutual acting height Eh1. Since the rollers are rotated, they become easy to move in an axial direction and, if they are perfectly meshed mutually at the flanks of the teeth, the tooth parts of them penetrate each other more deeply to generate smaller acting height Eh2. Therefore, the tooth parts are dynamically stabilized.
