Title: Fuel temperature adjusting device
Inventor: FURUTA KOICHI
IPC: F02M31/16
Filed: 1994-04-07
Abstract: PURPOSE:To provide a small-sized fuel temperature adjusting device which can detect fuel temperature, and heat and cool fuel through a simple construction. CONSTITUTION:A fuel temperature adjusting device is equipped with a Peltier element 30 provided in a channel for flowing fuel and a voltage detector 52 to detect voltage between both the terminals of the Peltier element 30, and moreover a power source section 30 which can apply the voltage to the Peltier element 30 and a control device 15 to drive the power source section 30. Since a heating or a cooling function section is formed into a solid structure having no motive power section, and the miniature Peltier element 30 having simplified construction is used, the acting face of the element can be applied to both cooling and heating only by inversing the electric polarity of plus-minus without using a special temperature sensor, and the precise temperature control of fuel therefore becomes possible.

Title: Optical waveguide having matching means
Inventor: MASUDA SHIGEFUMI
IPC: G02B6/122
Filed: 1981-05-08
Abstract: PURPOSE:To ensure the stable optical connection, by controlling the phase or amplitude of the reflected light by varying the termination length of the paried matching optical waveguides set at both sides of a main optical waveguide. CONSTITUTION:When an optical waveguide having a matching means is connected optically to another optical waveguide, a part of the signal light which is transmitted within a main optical waveguide 22 is reflected back at the connected part. Even in such case, a part of the signal light propagating within the waveguide 22 is transmitted to each paried matching optical waveguides, e.g., 25 amd 26 and then reflected by the control of the position shift of a termination controller 27 which is movably set on the waveguides 25 and 26 as well as by a reflective optical fim applied on a slant end surface 28 of the controller 27. As a result, the phase or amplitude of the light is varied. Thus the reflected light given from the above-mentioned connected part can be eliminated by such matched light.

Title: Voice call system
Inventor: ONISHI YOSHIO
IPC: H04N7/16
Filed: 1985-04-02
Abstract: PURPOSE:To make it possible to realize an outgoing/incoming proceduring using an oscillator having the same oscillating frequency by sending out immediately a busy tone to each terminal unit from a central unit when a tone signal with a frequency for a call from any terminal unit is sent out and prohibiting a voice call by the terminal unit which is not transmitting the tone signal. CONSTITUTION:With the call of any terminal unit TU, an f1 terminal outgoing 31 is transmitted to a central unit CU from a corresponding f1 oscillation control part 24. The central unit CU receives and discriminates the f1 terminal outgoing 31 at an f2 oscillation control part 14 and an f2 central outgoing 32 is transmitted to each terminal unit TU from the central unit CU. The corresponding terminal unit TU is made possible to call (33) with the central unit CU by the control of frequencies f1 and f2. The voice call of the terminal unit which is not corresponding is compulsorily prohibited by the busy signal of the frequency f2 and the impossibility of the call is continued until the turning-off of the busy signal. A recovery after the completion of the call is as follows: a system is returned to a normal standby state by an f1 terminal outgoing turn-off 34 and an f2 central outgoing turn-off 35 and is placed under the next re-call cycle 36.

Title: Noncondensed gas removing device for heat exchanger
Inventor: KOUTAKA IKUO
IPC: F28D15/00
Filed: 1979-06-07
Abstract: PURPOSE: To make a gas pool and valves unnecessary and miniaturize a device by a method wherein the gas pool is made by partitioning an upper header part of a condensing-pipe group and a heat-transmitting pipe connecting with the gas pool is made to be the heat-transmitting pipe for extracting the gas in a heat exchanger formed by using the heat transmitting pipe such as a heat pipe.  
     CONSTITUTION: When the part 24 provided in a gas-removing pipe 23 is kept to be closed, the vapor of a working liquid containing the noncondensed gas lowers from an upper header 4a through a heat-transmitting pipe 4 and is condensed through the heat exchange with the low-temperature gas. On the other hand, the noncondensed gas, after once flowing into a lower header through each heat-transmitting pipe 4, rises through a heat-transmitting pipe 15 for extracting gas and flows into a gas pool 14. A small quantity of vapor of a working liquid being contained at the time of rising conducts the heat exchange with the low-temperature gas and is condensed and flows down D along the wall of the pipe. Such a process is repeated and thereby the noncondensed gas G in the gas pool 14 is gradually concentrated.

Title: Shape measuring instrument
Inventor: NAKASHIRO MASAHIRO
IPC: G01B11/24
Filed: 1987-03-25
Abstract: PURPOSE:To measure the variation and defect of a body to be measured at the same time without any mutual operation by photodetecting reflected light and scattered light from the body to be measured by a two-dimensional image pickup element and separating and processing them by an image processing part. CONSTITUTION:If the body 3 to be measured has the defect, a light spot projected on the body 3 to be measured is scattered at the part. Consequently, a light spot shown in a figure is formed on the two-dimensional image pickup element 5. This spot is separated by the image processing part into the reflected light and scattered light. Namely, when >=2 light spots are detected in the picked-up two-dimensional signal, a spot which is close to a circle is decided and in other cases, it is decided that the light spot is generated by the scattering. Namely, K=(L/S) (L: peripheral length, S: area) and the spot is closer and closer to the circle as K is smaller and smaller. Then, the displacement of the reflected light from the position of the center of gravity is calculated to find the defect from the position and intensity of the scattered light.

IPC: F24F11/89
Filed: 1988-03-24
Abstract: PURPOSE:To improve detection response of power interruption, by comparing the time between zero crosses of commercial source voltage with a reference period and detecting power interruption based on the comparison result. CONSTITUTION:When a power source is thrown in, a microcomputer 5 measures the time between zero crosses of source voltage based on an output signal from a shaper circuit 15. Then main processing, e.g., turning ON of a triac 3 to supply power to a motor 2, is executed based on operation of an operation control switch 19 and the like. It is judged to be power interruption if instantaneous power interruption occurs during such operation and the output from the shaper circuit 15 does not rise to 'H' even upon elapse of time corresponding to a reference period. By such arrangement, power interruption detecting response is improved and even a relatively long power interruption can be coped with.

Title: Zinc recovering method from dust containing zinc
Inventor: MEGURO MASARU
IPC: C22B19/32
Filed: 1996-03-04
Abstract: PROBLEM TO BE SOLVED: To recover zinc at a low cost by roasting the dust in an oxidizing atmosphere and extracting zinc with a sulfuric acid aq. solution. SOLUTION: The dust is roasted at 700-950 deg.C at first. As a result, iron and zinc in the dust are converted into a zinc ferrite insoluble in an acid and further other fine powder is also aggregated to be precipitated in the next extraction. Next, the extraction is performed with the sulfuric acid aq. solution to obtain a zinc sulfate aq. solution. In such a case, the quantity of sulfuric acid in the extraction sulfuric acid aq. solution is controlled preferably to 0.9-0.6 in the ratio expressed by (the quantity of the extraction sulfuric acid aq. solution)/(the equivalent quantity of sulfuric acid necessary for extracting total zinc in the dust). As a result, fine silicic acid present in the dust is converted into silica gel to prevent the filtration of the extraction residue from being disturbed.  Since the clean zinc sulfate aq. solution containing no iron or silicon is obtained in this way, large equipment such as a wet zinc refining is unnecessary.
