Title: Polishing sheet and manufacture thereof
Inventor: KUNIMOTO AKIHIRO
IPC: B24D3/28
Filed: 1985-09-27
Abstract: PURPOSE:To enhance the heat resistant polishing ability at a high temperature, durability and chemical resistance of a polishing sheet, by holding abrasive grain dispersed uniformly in the polishing sheet, with the use of a biphenyl teta carbonic acid group aromatic polyimide. CONSTITUTION:Abrasive grain having an averaged particle size of about 0.1-50mum is uniformly dispersed in a solvent of organic polarity. An aromatic diamine component and an aromatic tetra carbon acid component are added while both components allowed to act upon each other at a temperature of 0-80 deg.C for 0.5-50hr to create aromatic polyamic acid so that the solution of aromatic polyamic acid in which the abrasive grain is dispersed is adjusted and prepared. Further, a liquid film is formed from the above-mentioned solution, and finally this liquid film is dried and solidified while aromatic polyamic is changed into the form of polyimide (imidizing), thereby it is possible to obtain a desired polishing sheet.

Title: Water pump
Inventor: HOTTA TAKAYUKI
IPC: F01P7/16
Filed: 1999-07-27
Abstract: PROBLEM TO BE SOLVED: To improve engine warming-up performance in a cold time by stopping the rotation of an electric motor while continuing excitation to the electric motor when the temperature of cooling water is the predetermined temperature or less in a water pump in which cooling water is circulated inside the engine by means of the electric motor. SOLUTION: When an engine is started, excitation to an electric motor 2 is started, and a rotor 5 is rotated by rotation of a rotating element 6, so that cooling water is circulated inside a cooling water passage 17. In this process, electric excitation switching control is carried out in an excitation control unit 14 in an engine cold starting time, and the rotation of the rotor 5 is stopped. Under this condition, excitation to a coil 8A is carried out continuously, so that the coil 8A is rapidly heated. Cooling water inside a cooling water storage chamber 11 is heated by heating of the coil 8A itself in addition to warming up by the engine.  When the cooling water is sufficiently heated inside the cooling water storage chamber 11, the excitation control unit 14 switches excitation so as to rotate the rotor 5 again for circulating the cooling water inside the cooling water storage chamber 11.

Title: Operating device of directional changeover valve
Inventor: IWASE YOSHIMI
IPC: F16K31/44
Filed: 1981-12-25
Abstract: PURPOSE:To improve the operational property of an operating lever by equalizing the stroke of the operating lever in the changeover in one direction to the stroke in the other direction with regard to two directional changeover valves operated by a single operating lever. CONSTITUTION:Both transmission rods 22, 24 are connected to an operating lever, and simultaneously moved in the same direction. When the transmission rods 22, 24 are displaced upwards, a pin 28 only moves in a long groove 25 to permit a pin 21 to be displaced upwards. Accordingly, the spool 7A of a changeover valve 6A is firstly switched. When the transmission rods 22, 24 are displaced further, a changeover valve 6B is also switched since the pin 28 is engaged with the end of a long groove 25, and displaced. When the transmission rods 22, 24 are displaced downwards from the positions shown in the figure, the pins 21, 28 are displaced together to switch the changeover valve. Accordingly, it is possible to equalize the strokes of the operating lever in both directions to improve the operational property of a device at the time of a fine operation.

Title: Loop type inter-multi-earthing digital communication equipment
Inventor: MARUYAMA TADASUKE
Filed: 1985-09-30
Abstract: PURPOSE:To attain inter-multi-earth digital communication with a nearly half lines in comparison with conventional lines by providing a storage circuit giving an output at a required time and a switch switching a test signal inputted to the reception side input from an output of the transmission side. CONSTITUTION:When an overflow take place, an overflow detection circuit 60 closes the PORTA of a switch 40 to open a PORTB so as to clear a storage circuit 50. The storage circuit 50 stores the input signals XA2 of a transmission side input (Sin)1 at a time 2 as 0. Since the switch 40, overflow detection circuit 60 and storage circuit 50 of stations B-F are operated similarly as those of the station A, the input signal of the sender input (Sin)1 of the stations B-F is outputted from the reception side output (Rout)4 of the station A. In the stations B-F, the input signal of the sender side input (Sin)1 of all the stations except its own station is outputted from the reception side output (Rout)4 of each station. Thus 2(N-1) lines are required for a conventional system, while the communication is attained by using N lines.

Title: Track error signal detection circuit for optical disk device
Inventor: OZAWA YASUYUKI
IPC: G11B7/09
Filed: 1986-09-11
Abstract: PURPOSE:To detect a track error signal, and to suppress the occurrence of offset with a simple constitution by generating a diagonal differential signal and a sum total signal from the outputs of a quadruple detector, deciding the direction of an error from the phase difference between the said two signals, then switching the output. CONSTITUTION:The four outputs of the quadruple light receiving element 8 that receives the reflected light from the medium of an optical disk device are added up to make the total signal Sa, and one of the diagonal two of the said outputs is subtracted from the other to make the diagonal differential signal Sd. Comparators 16, 17 respectively decide whether the total signal Sa and the diagonal differential signal Sd respectively are positive or negative, and a D-flip-flop circuit 18 latches the sign of the diagonal differential signal Sd i.e. the direction of the shifting at the time of rising or ending of the total signal Sa. Thereafter, a sign inverter 19 makes the diagonal differential signal Sd or -Sd depending on the decided direction of shifting. A multiplier 20 multiplies the original waveform signal Sd by the waveform Sd or -Sd after the said sign switching, to generate Sd<2> or -Sd<2>. The characteristic shown by broken lines as waveform (j) which is a track error signal, is obtained, by passing the signal of wave form (j) through a low-pass filter.
