Title: Static pressure gas linear guide apparatus
Inventor: SUZUKI YOJI
IPC: F16C32/06
Filed: 1986-01-31
Abstract: PURPOSE:To enable pollution in an atmosphere to be prevented, by recovering a gas blown out from gaps between a fixed body and a movable body by enclosures which are set up with an enclosing condition. CONSTITUTION:A compressed gas is transmitted via air holes 3b and gas guide grooves 3c, the gas exists in minute gaps S which are formed between the surface of a fixed body 2 and the inner wall surface of a movable body 3 and is blown out, so that the movable body 3 can be moved. At this time, the gas blown out from the gaps S is recovered from the internal space of enclosures 4, 5 through gas exhaust openings 6, 7. Thus, the gas is discharged out to atmospheric air or circulated so as to be recycled, so that pollution in an atmosphere can be prevented.

Title: Starting overload preventive method for rotary gas compressor
Inventor: HOSHINO MITSUO
IPC: F04C28/06
Filed: 1980-02-21
Abstract: PURPOSE: To prevent ocurrence of oil lock phenomena and damage of a compressor by allowing lubricant to begin flowing into the compressor after the driving unit has started completely, in case the compressor shall be started with its interior tank having residual pressure, and eliminating thereby flowing-in of too much lubricant.  
     CONSTITUTION: A solenoid operated valve 8 is opened, first when the start of the driving unit 1 is completed, by a timer 10 which is so set as to actuate the valve 8 just before a gas compressor 2 should go out of lubrication. The gas compressor 2 is thus fed with lubricant 7. Accordingly, even if the interior tank 4 has residual pressure which is well over the resistance of the delivery pipe 6 and presses forward its containing lubricant 7 to the pipe 6, the lubricant 7 will not reach the gas compressor 2 so long as the solenoid operated valve 8 is in closed position, i.e. the driving unit 1 has not fully started, that will well contribute to preventing the ocurrence of oil lock phenomena, damage of compressor and overloading to the driving unit 1.

Title: Time-division type d-a converter
Inventor: IKUTOSHI HIROSHI
IPC: H03M1/82
Filed: 1980-02-21
Abstract: PURPOSE:To secure a data holding function with a simple constitution for a time- division type D-A converter, by using a signal generating circuit, a selection circuit, a shift register and an AND circuit each. CONSTITUTION:The control circuit 2 which uses the oscillation pulse supplied from the pulse oscillator 1 for the input delivers alternately the clock signal A that defines n pieces of pulses generated with the time intervals of geometric progression as a period and the 1st pulse signal B generated after the signal A. At the same time, the 2nd pulse signal C is delivered as an on signal while the signal A is delivered. The shift register 3 which uses the n-bit data given from outside for the parallel input feeds the serial output back to the serial input and at the same time supplies the clock signal A as a shift register. The selection circuit 4 which uses the pulse signal B for the input generates the selection signal E only when tne pulse B is supplied under the conditions of the external signal D, and thus the register 3 reads the data of n-bits in parallel. The AND gate 5 delivers the serial output as it is to the integral network 6 while the pulse signal C is delivered and then converts the serial output into an analog signal.

Abstract: PURPOSE:To increase storage capacity of a luggage storage box, and to make the center of gravity of the luggage closer to that of a motorcycle by extending the rear part of the luggage storage box of the fore part of a cover covering a head pipe, to the inside of the cover, and by arranging the rear wall of the luggage storage box in proximity to and along the head pipe. CONSTITUTION:A luggage storage part comprises three parts, namely, a trunk 17 below a seat, a luggage storage chamber 23b in a leg shield 3, and a basket 28. Since a vehicle body is so formed that the rear part of the basket faces in a vehicle body cover 20 and since a rear wall D of the basket 28 runs along a head pipe 6, a part of the inner space of the vehicle body cover 20 can be used as a space for storing luggage. The center of gravity of the luggage stored in the basket 28 is thus closer to the center of gravity of the cover body. The luggage is constantly near the head pipe 6, since a bottom wall E of the basket 28 is tilted down backward, when the luggage is stored in the basket 28, and since the rear wall D is tilted along the head pipe 6.

Title: Amplifier
Inventor: BABA TATSUO
IPC: H03F3/34
Filed: 1982-02-16
Abstract: PURPOSE:To turn on a P channel transistor (TR) when an input signal is at a high level or an N channel TR when at a low level by biasing the gate of the P or N channel TR to some value, and superposing the input signal through a capacitor. CONSTITUTION:When the input signal is at the high level, a switch circuit D is turned on to obtain the value of a voltage VN1 by voltage-dividing the difference between a power voltage and the input signal voltage by the ratio between a resistance and a pullup resistance R when the switch circuit D is turned on, thereby holding an output terminal at the high level through a TRQP. When the input voltage rises from the low to the high level, the value of a voltage VN1 increases through capacity coupling to turn off the TRQ. At this time, the voltage at an input terminal is high, so even when the voltage VN1 rises to the value where the TR is turned off, the current path running through the switch circuit D is not formed and no discharge from a node N1 occurs. Therefore, the voltage VN1 is held high enough to turn off the TRQP.

Abstract: PURPOSE:To increase durability and lengthen life at a low cost by mixing partially cutting edges having edges made of high abrasion proof sintered diamond in plural cutting edges of a conventional rotary carbide cutter and designing a shape of the edges. CONSTITUTION:Among cutting edges 1-10, the cutting edges 3, 6 and 9 are diamond cutting edges and the remaining cutting edges 1, 2, 4, 5... are made of either carbide or high speed steel.

Then, in applying a sintered diamond to the cutter edge, not only a change of material from a conventional carbide cutter edge to the sintered diamond one but also the change of the tool shape is carried out. Namely, as for radial rake angles theta1 and theta2 of each cutting edge, theta1 is zero or plus value in the cutting edges 1, 2, 4, 5... and theta2 is zero or minus value in the cutting edges 3, 6.... With this the durability is increased and life is lengthened at a low cost.
