Title: Driving circuit for pressure generator
Inventor: TANAKA HITOSHI
IPC: H02M3/155
Filed: 1981-03-31
Abstract: PURPOSE:To execute a fail safe operation so that dangerous pressure is not generated, by constituting so that a pulse output is not sent to a transistor of the output side from an amplifier even if a pulse signal is applied, in case when a fault has occurred in a part related to a non-inversional input of the amplifier. CONSTITUTION:As for a voltage divider CRB, voltage VCC is applied through a resistance R3 from an electric power source and the other end is grounded, therefore, the voltage divider generates set voltage VSET obtained by dividing the voltage VCC, applies it to a noninversional input terminal, and feeds back output voltage Vf of an amplifier U2 to an inversional input terminal. In this case, a part related to this noninversional input becomes faulty, the noninversional input becomes an opened state, and input voltage of its input transistor TRQ3 rises up near the supply voltage VCC. When the TRQ3 is on, however, values of the resistances R3, R4 are selected so that voltage of the inversional input of the amplifier U2 does not exceed the noninversional input voltage, therefore, the amplifier U2 outputs no pulse even if a puls signal PS is applied to the base of the TRQ3. Accordingly, a load L is not driven by a pulse and pressure is not generated.

Filed: 1998-02-27
Abstract: PROBLEM TO BE SOLVED: To release a stress due to a difference of coefficient of linear thermal expansion between a semiconductor device and a mounting substrate and improve mounting property and reliability, by forming a lead-side projection projection from the wall surface of a package to the outer terminal exposing on the wall surface of a package.

Then, a lead-side projection 19 projecting from the bottom surface of a package 17 is provided to an outer terminal 16. The projection height of the lead-side projection 19 is kept as the minimum height for a solder 20. Thus, the thickness of the solder 20 to be applied to the outer terminal 16 can be made large. On the other hand, the solder 20 as a soft bonding material has a function to joint a semiconductor 10 to the mounting substrate 18, and it is soft enough to be deformed, thereby absorbing a thermal stress due to difference of coefficient of linear thermal expansion between the semiconductor device 10 and the mounting substrate 18.

Title: Temperature controller
Inventor: IKEHARA TAKASHI
IPC: G05D23/19
Filed: 1982-03-25
Abstract: PURPOSE:To perform the temperature control operation safely in case an operating part and a controlling circuit part are separated from each other, by stopping the conduction of a controlling element when a signal due to the non- resonance state is inputted continuously to a detector. CONSTITUTION:If a resonance signal is not inputted to a detector 9 for one cause on another and a comparator 12 outputs the H-level output continuously in case a table plate 2 is not arranged on a portable foot warmer body 1 and electric power is supplied, a capacitor 14 is charged through a resistance 13 and becomes a high potential. Therefore, the electric charge is discharged to the base of a transistor TR41 through a resistance 17, and the TR41 becomes conductive. Then, since the TR41 short-circuits electrically a thermistor 40, the -input of a comparator 34 becomes about zero volt, and the output of the comparator 34 becomes H-level, and TRs 30 and 26 are turned off. Consequently, a triac 53 does not become conductive, and electric power is not supplied to a heater 54. Thus, the temperature control operation is performed safely because electric power is not supplied to the heater 54 if the non-resonance state is continued.

Filed: 1997-02-18
Abstract: PROBLEM TO BE SOLVED: To perform high-quality grinding work without any scratches by dispersing free abrasive grains by using an instrument made of a material having hardness equal to or lower than an article to be machined. SOLUTION: The lower surface of an article 4 to be ground is pressed to a grinding tool 2 via abrasives 1, and the abrasives 1 are obtained by dispersing serium oxide fine particles in water and supplied from a nozzle 8 onto the grinding tool 2. For the adjustment of free abrasive grains (serium oxide) 17, water 17 and the abrasive grains 17 are put into a mortar (dispersing instrument) 11, a pestle (dispersing instrument) 13 is put into a mortar 12 and, by mixing the abrasive grains 17 with its tip, the abrasive grains 17 are dispersed in the water 15. At this time, primary agglomerated particles are difused. Here, the mortar 11 and the pestle 13 are made of optical glass identical to a material for the article 4 to be ground or fluorite or calcite softer than the optical glass.  Thus, the abrasives 17 separated from the pestle 13 during dispersing are not harder than the article 4 to be ground and cause no scratches.

SOLUTION: A CCD camera 203 inputs the moving image according to the frame rate set by a frame rate adjusting means 207 through a frame rate adjust knob and A/D converter 213 converts inputted analog moving image signals to digital moving image data and stores them in the frame memory of video compression/extension circuit 206. In this case, the circuit 206 compresses the moving image data inputted from the camera 203 and transfers them to a communication circuit 208. Then, the operating clock frequency of circuit 206 is controlled to an irreducibly minimum operating clock frequency according to the frame rate set by the adjusting means 207. Besides, when the frame rate is lower than a prescribed value, the circuit 206 is controlled so as not to perform motion compensation.
