Title: Beam expander and reducer
Inventor: KAWAGUCHI SHIGERU
IPC: B23K26/06
Filed: 1991-03-29
Abstract: PURPOSE:To increase the light resistance; reduce the disorder of a beam due to aberrations, and also reduce the size by arranging a convex parabolic mirror and a concave parabolic mirror so that their mirror surfaces face each other. CONSTITUTION:The convex parabolic mirror 1 and concave parabolic mirror 2 which are a confocal type and reflect reflected light at right angles to incident light are arranged having their parabolic surfaces opposite each other. The reflecting surfaces on the surfaces of the parabolic mirrors 1 and 2 are made of a material with high light resistance like Cu and Mo. A beam with a diameter d1 which is made incident from the side of the convex parabolic mirror 1 is reflected and expanded by the parabolic surfaces of the convex parabolic mirror 1 and concave parabolic mirror 2 and outputted as a beam with a diameter d2 from the concave parabolic mirror 2. The parabolic mirrors have no aberration, so the quality of the beam is not disordered and the incidence angle of the beam is set large. Therefore, the device can be made compact by making the interval between both the parabolic mirrors 1 and 2 small. When the incident light is made incident in the reverse direction, the device functions as the beam reduction unit.

Title: Heating and cooling method of solid substance
Inventor: TAKEORI MASATOSHI
IPC: C10B53/06
Filed: 1981-05-06
Abstract: PURPOSE:To increase the thermal efficiency of a fire grate by a method wherein a layer of oil  shales is heated and cooled on the fire grate for the purpose of colecting the oil component  from the oil shales, each of the functional zones of the fire grate is divided into a plurality of  sections and a gas is circulated vertically through the sections in such a manner that the flow  of the gas in one of the secctions is opposite to that in the section adjacent to the former  section. CONSTITUTION:A fire grate is divided into four zones of a heating zone 1, a residual carbon  combustion zone 2, a cooling zone 3 and an air preheating zone 4. Further, the circulating gas  G6 in one of the sections of the cooling zone 3 is blown to flow in the same direction as the  flow direction of the gas in the residual carbon combustion zone 2, that is, from up to down  vertically with respect to the transfer direction of the oil shale layer to thereby cool the upper part of the oil shale layer by the gas. Next, the oil shale layer is transferred to the adjoining  section in the cooling zone 3 where the circulating gas G6 is flowed upward from below to  thereby cool the lower part of the oil shale layer. Thus, when the oil shale layer passes the  cooling zone 3, it is transferred to the air preheating zone 4. In this case, the air preheating  zone 4 is divided into two sections and in these sections, the upper and the lower parts of the oil shale layer are cooled by air streams flowing vertically in opposite directions. As a consequence, the heat transfer between the circulating gas and the oil shale layer is improved.

Filed: 1979-06-01
Abstract: PURPOSE: To make it possible to attain accurate logging without a lag of a logging point in time by carrying out logging in the read/write cycle of a circuit control word by simple logic addition such as providing two circuit control word memories.  
     CONSTITUTION: Circuit control work memory 1, provided corresponding to circuits, uses memory addresses 1W(n) for the 1st group of circuit control words and n+1W 2n for the 2nd group of circuit control words. The 1st group is normally used and from when logging conditions are satisfied until all circuits are scanned, addresses are so changed by change-over control part 7 that after access from the 1st group is attained, updata contents will be written in the 2nd group. Then, the 2nd group is used to leave logging information in the 1st group. Namely, while logging detection latch 10 generates "1" and logging end latch 12 "0", the contents of the 1st group are logged in the 2nd group and when the count value of counter 11 reaches "n", latch 12 is set to send logging end signal 107 to address change-over control part 7.

Title: Photocurrent amplifying circuit
Inventor: OSAWA TOSHIFUMI
IPC: G01J1/44
Filed: 1985-04-03
Abstract: PURPOSE:To attain to enhance accuracy by preventing the saturation of the output of a circuit due to an external light component, by bypassing the low frequency component of the signal corresponding to the output of a photoelectric converting element by the level of the low frequency component of the output of the photoelectric converting element. CONSTITUTION:When the low frequency component in the photocurrent ip flowed to a resistor R1 becomes large and voltage with a predetermined value or more is applied between the base and emitter of a transistor TR, a part of the photocurrent ip is flowed between the emitter and collector of the transistor TR to bypass the low frequency component in the photocurrent ip flowed to the resistor R1. Even if the low frequency component of the photocurrent ip generated in a photodiode PD becomes large and the photocurrent ip flowed to the resistor R1 is apt to become large, the voltage between the base and emitter of the transistor TR becomes high and a larger current is flowed between the emitter and collector of the transistor TR. Therefore, it can be prevented that the output of a photocurrent amplifying circuit is saturated by an external light component and accuracy can be enhanced still more.

Title: Discriminating method of tooth having hit mark
Inventor: MAEHARA OSAMU
IPC: G01M13/02
Filed: 1982-04-23
Abstract: PURPOSE:To discriminate a tooth having a hit mark when the hit mark is being inspected, by fetching a reference signal of every one rotation of a gear together with a hit mark signal, and detecting a phase difference of both signals. CONSTITUTION:When a driving shaft 23 is rotated, its rotation is transmitted to a gear to be inspected 1 from a master gear 2, and various vibrations are generated. If there is a hit mark on the gear 1, when its tooth is engaged, vibration of comparatively high frequency is generated. These vibrations reach a vibration detector 3 through a shaft 11, a rolling center shaft 12 and a bearing part 14. On the other hand, a reference signal of every rotation of the gear 1 is fetched through a mark 4 on the shaft 11 and a mark detector 5. An output of the detector 3 is amplified, and after than, the high frequency component is fetched, and it is subjected to envelope detection, to compare it with a prescribed value by a comparator, and the hit mark is inspected. In this case, an FF36 is reset by a reference signal from the detector 5, is set by a signal from the comparator, and a phase difference is calculated by a phase difference operating circuit 37, by which a tooth having a hit mark is discriminated.
