Title: Light frequency converter
Inventor: TAKAI KIYOSHI
IPC: G02F2/02
Filed: 1990-03-30
Abstract: PURPOSE:To efficiently convert light frequency without increasing power density by Doppler-shifting a part of incident light upon the light frequency converter and changing its frequency at the time of reflecting a part of the incident light by a refractive index advancing wave propagated through an optical waveguide. CONSTITUTION:Light projected from a semiconductor laser 1 is made incident upon an optical waveguide 31 in an traveling wave type opto-electric element 3 through a beam splitter 2. A high frequency electric field impressed to one ends of electrodes 32, 33 is turned to a traveling wave, which is propagated between the electrodes 32, 33 in the left direction and arrives at a terminal resistor 5. Since a change in a refractive index is generated in accordance with the strength of the electric field, a refractive index traveling wave is generated in the optical waveguide 31 by Pockels effect in accordance with the electric field traveling wave. Although the light propagated through the waveguide 31 is reflected by the change of the refractive index, a part of the light is Doppler-shifted at the time of reflecting the partial light because the distribution of refractive indexes comes to a traveling wave. The reflected shifted light is reflected by the beam splitter 2, separated and extracted to the outside as frequency-converted output light.

Title: Brake fluid pressure control device
Inventor: WATANABE TAKASHI
IPC: B60T8/44
Filed: 1996-04-08
Abstract: PROBLEM TO BE SOLVED: To reduce the braking distance by prohibiting the flow of the brake fluid to a wheel braking force generating member while communicating the flow of the brake fluid between the wheel braking force generating members when the difference in the road surface condition is reversed when the brake fluid is adjusted at least either of first and second wheel braking force generating members. SOLUTION: When wheel cylinders (W/C) 5, 6 are boosted, a master pressure cut valve (SMC) 11 is communicated with control valves (SWC) 21, 22, while a control valve (SRE) 13 for reservoir is shut off. When the W/C 5 is boosted and the W/C 6 is kept, only the SWC 22 is shut off. When W/C 5 is boosted and the W/C 6 is decompressed, the W/C 5 is actually kept to make decompression of the W/C 6 preferential. That means, the SMC 11 and the SWC 21 are shut off, and the SWC 22 is communicated with the SRE 13, and the brake fluid in the wheel cylinder 6 flows into a reservoir 25 to achieve the decompression.

Title: Scum remover in floating or sedimentation separating tank
Inventor: AMANO YUUSUKE
IPC: C02F1/40
Filed: 1978-07-12
Abstract: PURPOSE: To enable scum to be removed efficiently without causing abrasion losses of a skimmer by letting a scum trough be kicked up by the skimmer when it comes to the position of this trough and letting a scum influent port descend when the skimmer approaches to the scum trough.  
     CONSTITUTION: When a skimmer 9 swivels while skimming off and gathering the scum on water surface 7 and approaches to a scum trough 11, the engager 16 of a skimmer arm 5 abuts against the lower pin 15 of the scum trough 11 and causes the scum trough 11 to rotate. This causes a scum influent port 12 to lower and the gathered scum to enter the inside of the scum trough 11 through the influent port 12. The scum is then discharged to the outside of the tank. When the skimmer 9 further swivels and approaches to the scum trough 11, the cam 10 on the outside circumferential end of a shaft 8 abuts against a guide rod 13, by which the skimmer 9 is kicked up so as to turn backward and upward, thus it passes without touching the scum trough 11.

Abstract: PURPOSE:To reduce an occupying space of a main freezer and make a small-sized freezer by a method wherein a compression space, a radiator, a hold over, a heat exchanger and an expansion space are arranged substantially on the same axis. CONSTITUTION:Working gas compressed in a compression spacing 101 is cooled by freezed state generated in the second expansion spacing 209 of a subfreezer 200 when the working gas passes through a radiator 102, the gas passes through a hold over 103, is cooled to a lower temperature, passes through a heat exchanger 104, flows into an expansion spacing 105, is isothermally expanded under an upward movement of a head 109 to generate a freezed state of about 4.2k. For example, the working gas in an expansion spacing 105 passes through the heat exchanger 104 under a downward movement of the head 109. At this time, herium vapor in a tank 103 passes through a pipe 130 and further passes through the inside part of the heat exchanger 104. The herium vapor is cooled by the working gas of about 4.2K to become liquid, the liquid passes through a pipe 129 and is accumulated in a liquid phase part 131a of a tank 131. The working gas passes through the heat exchanger 104 passes in sequence through the hold over 103, and a radiator 102, its temperature is increased and then working gas returns to the compression spacing 101 so as to complete one cycle.

But this side of a connecting joint 19 is made higher to the vertical direction than a 1Hp circuit 15, to drop the liquefied refrigerant carrier to a certain degrees, so that the gas refrigerant carrier remains much in quantity on the side of a connecting joint 19. With such an arrangement, the weight of a refrigerant carrier which is gathered in the connecting joint 19 can be made little in quantity, accordingly, the circulating rate of the refrigerant carrier can be extremely prevented from decreasing, and sufficient capacity can be obtained from the gas refrigerant carrier.

Abstract: PROBLEM TO BE SOLVED: To make an electrolytic tester provided with a catalyst consume the purification capacity of the catalyst close to its limitation and reduce frequency of replacing the catalyst. SOLUTION: This electrolytic tester is provided with a DC power source electrifying through a test body in the electrolyte and between eletrodes, a catalyst purifying harmful gas generated in the electrolyte during electrification, and a judgement device 270 for judging the time for replacing the catalyst. The catalyst purification capacity is indicated as an active current amount C1 which is the product of the current and time. After the judgement device 270 finding a residual active current amount C4 of the catalyst on the basis of the active current amount C1 and a consumed current amount C2 of the catalyst, it compares the residual active current amount C4 with an estimated consumption current amount C5 when the test is started and sends a catalyst replacement signal when it is C4 <C5 .  By controlling the catalyst replacement time by the current amount, economical efficiency can be improved by consuming the purification capacity of the catalyst up to or close to its limitation and test operating efficiency can be improved by drastically reducing the frequency of replacing the catalyst.
