Filed: 1998-10-09
Abstract: PROBLEM TO BE SOLVED: To obtain an electric pump which prevents degradation in a pumping function resulting from increased viscosity caused by a temperature fall of a fluid to be discharged stored in a reservoir, and which causes no disadvantages resulting from a pressure loss and damage of a fluid passage between a reservoir and a pump. SOLUTION: This electric pump includes a pump portion 7 for discharging a fluid by reciprocating of a piston 5 contained in a housing 3; a piston driving portion 11 for reciprocating the piston 5, the piston driving portion 11 having a super-magnetostrictive element 9 which is extended in response to application of a magnetic field, and a coil 22 for applying the magnetic field to the super- magnetostrictive element 9 by application of a current; and a reservoir 24 for storing the fluid to be discharged to be supplied to an inlet port 12b of the pump portion 7. In this electric pump, the reservoir 24 is installed in a heating region of the coil 22 so as to prevent a temperature fall of the fluid to be discharged within the reservoir 24 and to shorten a fluid passage 46 from the reservoir 24 to the pump portion 7.

Title: Load controller
Inventor: TAKAMATSU SEIETSU
IPC: H02J3/00
Filed: 1989-11-06
Abstract: PURPOSE:To detect chattering in an electromagnetic contactor accurately by producing an alarm signal from a logical operation circuit when a detected time variation rate of main circuit current exceeds a reference current variation rate stored in a memory means. CONSTITUTION:Upon occurrence of chattering in an electromagnetic contact section 5, main circuit current fluctuates considerably at chattering parts thus producing a sawtooth waveform. Consequently, variation rate signal Svf to be outputted from a differentiating circuit 20 increases at the chattering parts. When a reference current variation rate to be stored in a memory circuit 18 is set higher than the variation rate signal Svf at the time of chattering in the electromagnetic contactor 5, a logical operation circuit 11 outputs an alarm signal Sa through an output circuit 21 it a relation, i.e., variation rate signal Svf > reference voltage variation rate, is satisfied upon occurrence of chattering.

IPC: G02F1/133
Filed: 1989-11-06
Abstract: PURPOSE:To execute highly reliable inspection automatically at a high speed by projecting light on the picture elements of a driven liquid crystal display panel, and computing the light transmittance of each picture element for the output signal of an IC under inspection. CONSTITUTION:When n picture elements 41 on one line of a liquid crystal panel 4 are driven by n X driving signals outputted from a liquid-crystal-display driving IC 1 which is the IC under inspection through an electrode 12 and the signals from a Y driver 6, the entire group of the picture elements 41 are uniformly illuminated with a lighting system 7. The images of the transmitted light beams 7 are formed on a CD sensor 82 through an image forming lens 81. The sensor 82 decomposes the transmitted light for every picture element 41 and converts it to electrical signals. The electrical signals are sent into a data processing device 9. The device 9 receives the data with regard to the power source level for the IC 1 and the combination of the driving level signals from a signal generator 3, computes the light transmittance of each picture element 41, compares the transmittance with a predetermined standard value and judges the quality of the IC 1. When the inspection is finished, a carrier tape 11 is automatically sent, and the next IC 1 is inspected.

Title: Roller recording sheet feed type recording device
Inventor: SHIRAHATA ATSUSHI
IPC: B65H20/02
Filed: 1985-12-20
Abstract: PURPOSE:To obtain a satisfactory written image, by providing such an arrangement that the peripheral speed of one of drive and auxiliary rollers in a drive section, which is positioned forward in the direction of feed of a recording sheet, is made to be higher than that of the other, and therefore the writing position of a recording pen is regulated under a suitable tension. CONSTITUTION:In the relationship between a drive roller 41 and an auxiliary roller 21, the peripheral speed of the one which is located forward in the direction of feed of a recording sheet 3 is made to be larger than that of the other. Accordingly, when the recording sheet 3 is fed rightward, the peripheral speed v2 of the auxiliary roller 21 is made to be higher than the peripheral speed v1 of the drive roller 41. Meanwhile, when the recording sheet 3 is fed leftward, the peripheral speed v2 of the auxiliary roller 21 is lower than the peripheral speed v1 of the drive roller 41. In this arrangement, the peripheral speed v1 of the drive roller 41 writes a precise image under the control of a control circuit alone, and the relationship between the peripheral speeds v1, v2 is changed by changing the speed v2 of the auxiliary roller 21. Further, the difference between the speeds causes a slip between the recording sheet 3 and the auxiliary roller 21, resulting in the recording sheet 3 being always stretched. Accordingly, the writing position of a recording pen 1 is regulated under suitable tension, thereby it is possible to obtain a satisfactory written image.

Filed: 1988-11-16
Abstract: PURPOSE:To selectively prepare the labeled body which has enzyme activity and is not so much large in mol. wt. by isolating the enzyme-labeled antibody or antigen from an insoluble carrier. CONSTITUTION:The antibody or antigen is temporarily immobilized to the carrier and after the enzyme is conjugated with the immobilized antibody or antigen, the carrier is cleaned to remove the free enzyme.

All the enzymes used for ordinary enzyme labeling are usable as the enzyme. The antibody is exemplified by all antibodies, such as polyclonal antibodies and monoclonal antibodies, normally used for enzyme immunoasay (EIA). Any carriers which are insoluble in water and have the spaces into or out of which the enzyme or the antibody or antigen can freely go are usable as the insoluble carrier.

Title: Dynamic pressure bearing device and its manufacture
Inventor: KOBAYASHI TOSHIHIRO
IPC: F16C33/14
Filed: 1997-10-07
Abstract: PROBLEM TO BE SOLVED: To improve bearing characteristics by forming a lubricating film on one of dynamic bearings of a shaft body and a shaft fitting body through electrodeposition, and thereby providing the bering with satisfactory smoothness. SOLUTION: A blank 15a of a bearing is formed, while surface treatment such as chromate process is performed on an inner peripheral surface of the blank 15a for improving corrosion resistance and painting closability. The resultant bearing material is sunk in an electrodeposition bath to apply electrodeposition to all surfaces of the bearing material. A lubricating film 36 having even thickness is easily formed on a bearing side by such electrodeposition. The lubricating film 36 prepared by electrodeposition shows satisfactory lubricancy because lubricating grains are floated on the surface of the paint in electrodeposition. Bearing characteristics are thus improved.
