Title: Ceramic package
Inventor: HIRAI MICHIO
IPC: H01L23/02
Filed: 1990-02-08
Abstract: PURPOSE:To obtain a package with a thin type and light weight ceramic cap having excellent heat radiation performance by manufacturing ceramic package caps by a sol-gel processing from alumina. CONSTITUTION:After aluminum metal and isopropyl alcohol are mixed to a satisfactory extent, it is possible to produce an aluminum alkoxide solution having a high degree of purity by distillation. Then, water is applied to the mixed solution of aluminum alkoxide so as to carry out hydrolysis and further form boehmite sol by peptizing operation. After an organic binder is added to the boehmite sol to enrich and control their viscosity, green sheets are produced by casting and drying. Then, the green sheets are fined and cut to a specified size to produce ceramic package caps. The caps which are 0.05 to 0.4mm thick and low weight, are available. The package is provided with a semiconductor element 2 incorporated into a cavity of an aluminum board 1. Then, the entire package is covered with a cap 3 after a lead 5 is wire- bonded, bonding with metal or a glass-based bonding agent so that the package is sealed.

Title: Parallel conveyance copying machine
Inventor: HIRONO TATSUO
IPC: G03G21/00
Filed: 1985-02-19
Abstract: PURPOSE:To increase a copy speed while holding the process speed of image formation constant by conveying sheets of transfer paper in parallel and erasing the gap between the sheets of transfer paper. CONSTITUTION:When a gap is provided between both sheets of transfer paper, untransferred toner is present at a position on a photosensitive body which correspond to the gap during transfer to both sheets of transfer paper. The untransferred toner causes no trouble when the number of times of parallel conveyance copying operation is small, but the load on a cleaning unit increases as the number of times increase and a black stripe, etc., may be formed on an image in normal copying if a cleaning defect occurs. For the purpose, the light emitting element 23a in an erasing lamp 23 is turned on so as to provide erasure width delta at a specific position on the photosensitive body 21. A light shielding plate 23b controls the erasure width on the photosensitive body 21.

Abstract: PURPOSE: To automatically judge the necessity of remeasurement of a sample and automatically set the measuring conditions, without using human power, by picking up sample and reagent for remeasurement by using a control unit.  
     CONSTITUTION: Sample-holding containers 1 are sent to a sample suction position by a sample container transfer means 2. The sample is sucked into a nozzle 4 by a sample dispenser 3 and injected into reaction vessels 5. Reagent vessels 7 transferred by a reaction vessel transfer means 6 are selected by a reagent selector 8. The reagent is injected into the reaction vessels 5 by a reagent dispenser 9, and the reaction vessels 5 are then transferred by the means 6 to a measuring position where the absorbancy of the reaction liquid is measured by a photometer 13. The measurement data are input into an operator 14 to obtain an active value. The active value is sent to CPU15 in which the active value is compared with a setting value which has been inputted into the CPU15 beforehand. When the active value is not in agreement with the setting value, an instruction is given to a control unit 16 so that the amounts of injection from the dispensers 3, 9, and the movements of the sample container transfer means 2 and reagent selector are controlled for remeasurement of the sample.

Title: Piezo-oscillator
Inventor: ABE YUTAKA
IPC: H03B1/04
Filed: 1978-03-14
Abstract: PURPOSE: To suppress the oscillation outside the fixed frequency by adding the inductance to the capacitor to satisfy the phase conditions of the oscillator.  
     CONSTITUTION: The capacitors are connected across the piezoelectric oscillator in order to satisfy the phase conditions of the oscillation, and inductance 31 and 37 are connected in series to those capacitors 32 and 33 each. These capacitors and inductances form two resonance circuits 1 and 2. Here, the basic frequency of the piezoelectric oscillator is referred to as ω 1 , the 3rd overtone is ω 3  and the 5th overtone is ω 5  respectively. The circuit becomes capacitive near ω 3  in relation to the resonance circuit and features inductive at other frequencies, thus no oscillation secured. Furthermore, the oscillation can be suppressed for the unneessary mode, thus increasing the loop gain to the necessary frequency of the circuit and then ensuring the steady oscillations.

Title: Earthquake motion estimating method
Inventor: FUJITA YUSUKE
IPC: F17D5/00
Filed: 1998-02-12
Abstract: PROBLEM TO BE SOLVED: To precisely estimate the magnitude of earthquake motion at a point where a seismometer is not installed, on the occurrence of earthquake. SOLUTION: From a seismometer 10 installed on a ground surface 12, the magnitude of earthquake motion at an at-random estimation point 11 in a predetermined range of estimation area 16 is found by estimating the magnitude of earthquake motion on a technically basement surface 13. The magnitude of earthquake motion at a point 10a on the technically basement surface 13 corresponding to the installation point of the seismometer 10 is estimated by the division by an earthquake amplification factor on a surface layer stratum 14. The magnitude of earthquake motion in a reference area 15 on the technically basement surface 13 is identical with a value converted in accordance with an observation value on the seismometer 10 in a narrow range and estimated in accordance with a range damping formula in a wide range.  The magnitude of earthquake motion at an estimation point 11 is found by the multiplication by the amplification factor of earthquake motion at the surface layer stratum 14.

Title: Constant voltage output circuit
Inventor: SHINOHARA MASATO
IPC: G05F3/30
Filed: 1997-02-14
Abstract: PROBLEM TO BE SOLVED: To expand the degree of freedom of a choice of a set value of constant voltage output by determining the common base potential of 1st and 2nd bipolar transistors(TR) so that the emitter potential of the 1st bipolar TR becomes equal to the potential at the connection part between 2nd and 3rd resistances. SOLUTION: The bipolar transistors(BJT) 11 and 12 have current amplification factors which are much larger than 1 as well as general BJTs and their ratios of collector currents and emitter currents are therefore almost equal to 1. At this time, resistance values R1 and R0 are determined in exactly the same way as R1 and R0 which are determined in a conventional examples; and a constant voltage output which depends upon neither a source voltage nor temperature is developed at a terminal 17 and its value is determined by the voltage drop across the resistance R0 and the base-emitter potential difference of the BJTs 11 and 12, so it is approximately 1.2V as well as the conventional example. Consequently, the constant voltage output can be actualized through a simpler manufacture process than before.
