Title: Switching regulator integrated circuit
Inventor: SHIMODA SADAYUKI
IPC: H02M3/155
Filed: 1989-04-18
Abstract: PURPOSE:To miniaturize a transistor by a method wherein the power source voltage of a switching regulator(SR) is supplied from the output of a charge pump voltage converter (CP) while the input of the CP is supplied from a higher voltage between the input voltage and the output voltage of the SR. CONSTITUTION:The title circuit is constituted of a switching regulator(SR) 15, a voltage detector (VS) 4, transistor(Tr) 5, 6, charge pump voltage converter (CP) 16 and the like. Immediately after a voltage is inputted from an input terminal 1, the voltage of an output terminal 2 is lower than an input voltage, the output of the VS 4 becomes low in level, the Tr 6 is out ON and the Tr 5 is out off. As a result, an input voltage is impressed on the input terminal 7 of the CP 16. When a time has elapsed, the voltage of the output terminal 2 of the SR 15 is increased, the output terminal of the VS 4 becomes high in level, the Tr 6 is put OFF and the Tr 5 input ON. A voltage, several times of the output voltage of the SR 15, is outputted from the output terminal 9 of the CP 16. According to this method the ON-resistance of the Trs may be reduce, the Trs may be miniaturized and the efficiency of the same may be increased.

IPC: C25C1/20
Filed: 1986-04-28
Abstract: PURPOSE:To efficiently recover Rh, Pt and Pd from an ammonium rhodium nitrite filtrate by electrolyzing the filtrate in an electrolytic cell. CONSTITUTION:An ammonium rhodium nitrite filtrate 7 having about 50mg/l initial concn. of Rh and about 470mg/l initial concn. of Pt is poured into an electrolytic cell 1, and the anode 3 and the cathode 4 are placed in the cell 1 so that about 4cm interval is left between the electrodes.

Title: Heat-storing structural building material
Inventor: HAYASHI YUICHI
IPC: C04B40/00
Filed: 1992-03-24
Abstract: PURPOSE:To provide the building material which suffers neither the exudation of the heat storage component or the change in its appearance. CONSTITUTION:The building material comprises a structural building material and a heat storage material dispersed therein. The heat storage material comprises a mixture prepared by mechanically mixing 100 pts.wt. paraffin as a heat storage component with 5-30 pts.wt. organic hydrocarbon polymer as a binder component. Thus, the surface treatment of the heat storage material, the formation of a shielding layer in the structural building material and the use of a container or tank for holding the heat storage material can be dispensed with, so that the production process for the heat-storing-structural building material can be abridged, and the production cost can be reduced. Further, the amount of heat stored can be increased and the heat absorption and dissipation can be performed at good efficiency, and the running cost of the equipment for controlling the room temperature can be markedly reduced.

Title: Vehicle speed detecting device
Inventor: YAMANE TOSHIKI
IPC: G01P3/489
Filed: 1990-04-14
Abstract: PURPOSE:To make vehicle speed detection accurate and make its response speedy by detecting an optional ON-to-OFF change point of time, storing an elapsed time clocked by a timer circuit, and finding a vehicle speed from the elapsed time of one rotation of an axle shaft. CONSTITUTION:The output signal of a vehicle sensor 1 is the ON-OFF switch of a reed switch. The vehicle speed detecting device passes this signal A through a buffer circuit 2 and then a CR integration circuit 3 shapes the signal into a specific waveform to prevent the miscalculation output of the vehicle speed due to chattering. Then the point of time when the ON-OFF signal turns on is detected as a pulse B and the timer circuit 4 clocks the elapsed time between edges as a vehicle speed pulse interval. Elapsed time data outputted from this timer circuit 4 is stored in a storage circuit 6 by at least one rotation. A vehicle speed calculating circuit 5 finds the vehicle speed from this stored elapsed time of one rotation of the axle shaft. Then the vehicle speed can accurately be detected and the fast-response vehicle speed detection becomes possible.

Title: Printing pattern generator
IPC: G06F3/12
Filed: 1992-03-25
Abstract: PURPOSE:To prolong the life of a specific dot by a method wherein printing density is lowered and damage to paper to be printed on is lessened. CONSTITUTION:A standard pattern generator 1 makes a dot image designed compactly. A thinning out setter 2 sets density of printing to be standard or lighter. A thinning out discriminator 3 discriminates whether or not thinning out will be carried out based on discriminative information and set information. When the information is discriminated as thinning out, a thinning out controller 4 performs thinning out processing of the dot image based on a dot image made with the standard pattern generator 1. The dot image thinned out with the thinning out controller 4 is printed on printing paper via a printing controller 5.

IPC: B41J3/36
Filed: 1992-04-20
Abstract: PURPOSE:To perform the peeling of a label from the mount automatically by a method wherein a shaft which suddenly bends and guides the running direction of the mount of a label paper is provided, and the mount which has passed the shaft is run-driven by a carrying roller. CONSTITUTION:For the label printer, after installing a label paper 5 on a platen 2 so that the label paper 5 goes through between a thermal head 1 and the platen 2, the part on which a mount 9 only exists at the leading end of the label paper 5 is installed on shafts 3, 4. Then, after changing the running direction of the label paper 5 suddenly, the label paper 5 is made to go through between a pair of carrying rollers 6. When a printing is performed on a label 8 under this condition, the label paper 5 is carried in the direction B by the platen 2, but the mount 9 at the leading end of the label paper 5 is carried in the direction A by the carrying rollers 6.

Title: Supporter for electrophoresis and electrophoretic method using said supporter
Inventor: MORI YUICHI
IPC: G01N27/447
Filed: 1990-04-13
Abstract: PURPOSE: To separate protein based on the difference of hydrophobicity or hydrophilicity by using a temperature-sensitive polymer compound having hydrophobic, hydrophilic transition temperature (LCST) as a support for electrophoresis. CONSTITUTION: A carrier is coated or grafted with a temperature-sensitive polymer compound having LCST, e.g. a poly-N substituted acrylamide derivative, to compose a support for electrophoresis. When a sample is fed to the support and electrophoresis is started at a temperature higher than LCST, hydrophobic bond is formed between a protein having high hydrophobicity and the support because the support is hydrophobic and electrophoresis thereof is blocked. When the temperature is lowered below LCST, the support becomes hydrophilic and the affinity to hydrophobic protein is lowered. Consequently, blocking of electrophoresis is released and the affinity of the support to a hydrophilic protein is increased thus blocking electrophoresis thereof.  Since the electrophoresis is performed at temperatures above and below the LCST, proteins can be separated easily and definitely even if the molecular weight and the amount of charge are substantially identical.
