Title: Reflector for lighting apparatus
Inventor: MARUYAMA TATSUO
IPC: G02B5/08
Filed: 1989-10-31
Abstract: PURPOSE:To prevent the temperature of a reflector base from rising by constituting with the reflector base made of plastic, an undercoat formed on the surface of the base, a high temperature conduction film formed on the undercoat, and a reflector film formed on the conduction film. CONSTITUTION:The light injected from a light source into a reflector 6 passes through a reflection enhancing film 5, reflects on the surface of a reflector film 4, and emitted outside. The reflector film 4 is subjected to a high temperature and heated due to heat radiation from the light source and heat conduction through the air. A high temperature conduction film 3 is heated with the heat conduction from the reflector film 4. The heat of the high temperature conduction film 3 is diffused to the surrounding area through heat conduction so that the heat conduction to a base 1 is reduced. Since an undercoat 2 reduces the heat conduction to the base 1, high temperature concentration does not occur locally on the base 1 and the undercoat 2. If a diamond layer is formed on the high temperature conduction film 3, the coefficient of heat conduction is 5.0Cal/cm.sec. deg.C and the heat diffusion is improved.

Abstract: PROBLEM TO BE SOLVED: To have a hard-to-adhere oligomer produced by the decomposition of polyester resin to a movable mold, and thus reduce the main-hour of cleaning the mold by forming minute unevennesses on the bottom wall inner surface of a cupped vessel in order to improve its releasing property from a mold. SOLUTION: The cupped, injection-molded beverage vessel 1 consists of polyester resin, and fine unevennesses are formed on the whole part of the inner surface of a bottom wall 2b. The fine unevennesses are made by giving blast work onto a mold surface for forming an inner surface of the bottom wall 2b in the movable mold of a mold for injection-molded articles. Besides, a roughness of the unevennesses is preferably made 20 μm or lower in order to maintain transparency of the bottom wall 2b. However, it is most suitable to produce vessels in the order of 5 μm for a sufficient releasing property.

Filed: 1988-11-11
Abstract: PURPOSE:To measure a voltage accurately without being affected by an electrode in the vicinity by connecting a high-voltage electrode to a high-voltage conductor through a high-voltage lead-in cable. CONSTITUTION:A disk-shaped floating electrode 1 is so disposed that an insulator sheet 3 is held between the same and an earthing potential metal 2, and a stray capacity c2 is formed between them. Between the floating electrode 1 and a high-voltage electrode 12 the potential of which is made identical with that of a high-voltage conductor through a high-voltage lead-in cable 11, a stray capacity c1is formed. These capacities c1 and c2 form a capacity divider. The surface of the high-voltage electrode 12 is converted with a resin mold element 13, which seals up also a space between the high-voltage electrode 12 and the floating electrode 1, and a dielectric 14 is packed in this space. Since the potential of the high-voltage electrode is made identical with that of the high-voltage conductor through the high-voltage lead-in cable, accordingly, the high-voltage side capacity of the capacity divider is larger and thus it is not affected by the potential of another electrode.

Filed: 1997-10-16
Abstract: PROBLEM TO BE SOLVED: To obtain a gas detector for gas-sealing equipment without any possibility of performance deterioration and function stop due to the exhaustion of an electrolyte. SOLUTION: A small amount of impurity gas in an SF6 gas inside a gas breaker 1 is detected by an electrochemical sensor 2. Since the sensor 2 is used while being in contact with an extremely dry SF6 gas atmosphere, an electrolyte in the sensor 2 evaporates and hence decreases. At this time, the electrolyte being stored in an electrolyte spare bath 201 is replenished into the electrochemical sensor 2 by an electrolyte-filling means 202.

Abstract: PURPOSE:To improve moisture resistance and contamination resistance effect with a passivation insulating film improved in bondability by forming a base film of plasma silicon nitride by the process of combining vapor grown silicon oxide films different in vapor growth conditions, coating glass, and etchback. CONSTITUTION:A first silicon oxide film 14 is grown by plasma vapor reaction of TEOS [Si(OC2H5)4] and O2, and then a second silicon oxide film 15 is piled up by thermal reaction under a reduced pressure of TEOS and O3. The second silicon oxide film 15 is cleared of a portion at a flat area by anisotropic etchback to remain at the space of a metal wiring 13 as a side wall. Sintering and curing in an H2/Ar atmosphere after spin-coating with a coat glass 16 make coat glass 16 accumulate over a wide range of flat area, on steps and in grooves to flatten them. Next, the coat glass 16 at the wide range of flat area is removed by sputter etchback in an Ar atmosphere. Further, a third silicon oxide film 17 is grown and so is a silicon nitride film 18 that results from plasma reaction of SiH4 and NH3.

Title: Moving object detector
Inventor: MIKAMI SHIGENOBU
IPC: G01S7/52
Filed: 1985-12-18
Abstract: PURPOSE:To achieve a higher detection accuracy, by providing one ultrasonic vibrator adapted to transmit an ultrasonic wave while receiving the reflected wave thereof to control the vibrator so that it is always excited in non- resonance area along with a minimized effect of noises. CONSTITUTION:An excitation signal with a fixed amplitude is outputted from a generator 2. When the excitation signal is applied to a vibrator 1, an ultrasonic wave T is transmitted from the vibrator 1. When an object exists at a specified space and an ultrasonic wave is reflected therefrom, the vibrator 1 is displaced mechanically, causing a new current to flow to a resistance 4 to generate a signal across the resistance 4. Now when the object is at rest, there is no change in the amplitude of a signal generated across the resistance 4 and no signal is outputted from a comparator 7. On the other hand, when the object is moving, the size and the phase of a reflected wave R changes and so, a detection signal appears at the output of a detector 5 according to the changes in the amplitude of the signal. When this signal is compared 7 with a specified voltage, a signal is outputted at a terminal 8 according to the movement of the object.

When auxiliary cleaning holes 16 are formed at intervals in the peripheral direction on a cylindrical wall of the tip of the nozzle 12 and tip jet opening 17 of the nozzle 12 is set in the closed state or the half-closed state, a gas-liquid mixed cleaning liquid is jetted out of the auxiliary cleaning holes 16 to clean the blind-hole peripheral face. Namely, the auxiliary cleaning holes 16 are of the opening dimension of not jetting the cleaning liquid when the tip jet opening 17 is released and is preferably formed of an arc-shaped slit 16' extended in the peripheral direction of the cylindrical wall. The cleaning liquid can be utilized effectively not only on the blind-hole inner bottom face but also on the inner peripheral face by this arrangement.

Title: Speedometer apparatus for railroad
Inventor: YOSHIDA TAKASHI
IPC: G01P3/49
Filed: 1994-11-18
Abstract: PURPOSE: To eliminate errors resulting from a slip and realize highly accurate measurement by operating the moving speed of a plurality of magnetic detecting bodies to a rail from a magnetic flux difference measured by the magnetic detecting bodies set at a car along the rail. CONSTITUTION: A speed detector 1 set in the lower part of a car 5 to face a railroad rail 6 has magnetic flux-detecting elements 4a, 4b symmetric to each other via a magnetic flux-generating coil 3. The elements 4a, 4b are mounted at the front and rear sides in the advancing direction of the car to detect a magnetic flux generated by the coil 3. In other words, when a current is fed to the coil 3, a magnetic flux is generated and enters a conductive body, thereby, an eddy current runs around the magnetic flux within the conductive body. The eddy current generates a secondary magnetic flux in a direction to offset the original primary magnetic flux. The elements 4a, 4b detect a difference of the primary and secondary magnetic fluxes.  A speed-operating mechanism 10 operates the moving speed of the elements 4a, 4b to the rail 6 from the measured magnetic flux difference by the elements 4a, 4b. Accordingly, the moving speed can be detected highly accurately at a high speed without errors due to slip.
