Title: Glow plug for diesel engine
Inventor: KIKUCHI TETSUO
IPC: F23Q7/00
Filed: 1981-06-09
Abstract: PURPOSE:To enable a long-time energization from a battery eliminating waste of power free of the conventional external resistance for switching current by arranging two heaters for preheating the engine and after glow treatment each having an optimum resistance value into the same glow plug. CONSTITUTION:A glow plug for the diesel engine is used for preheating prior to the start up thereof and for after glow treatment to prevent idle noise and control exhaust hydrocarbon thereafter. After the start up of the engine there is no need for supplying the same power to the glow plug as that prior to the start up thereof and hence, the power is changed over with switches 1 and 2. They are connected at one point 531 on the tip 53 of a tube of the plug separately via a high resistance heater 52 and a low resistance heater 51. The two heaters are connected to external lead terminals independent of each other. This sysem requires no external resistance for changing the level of current and eliminates waste of power otherwise caused by the conventional resistance thereby enabling a long-time energization from a battery.

Title: Optical disk medium
Inventor: MIYAGI MASAMI
IPC: G11B7/24
Filed: 1983-05-20
Abstract: PURPOSE:To inhibit the occurrence of defects due to the transfer of a groove, to obtain a track signal of high quality, and to record and reproduce information in a high signal/noise ratio by forming a thin film of a substance which expands when irradiated with light on a disk substrate and by irradiating the film with converged laser beams to form directly a track on the substrate. CONSTITUTION:A track forming thin film 22 such as a thin film of amorphous silicon contg. hydrogen is formed on a substrate 21 by a plasma CVD method. When the film 22 is irradiated with light having a wavelength at its absorption edge or shorter, it absorbs the light and generates heat, so hydrogen in the film is released, and the film expands. In order to expand the track forming part, the track forming position is irradiated with converged Ar laser light having 5145Angstrom  wavelength to form a track 23. A metallic thin film of Te, a Te compound or the like is then formed as an information recording thin film 24 to obtain an optical disk medium.

Filed: 1993-03-24
Abstract: PURPOSE:To improve the productivity of a semiconductor without lowering the synthesizing temperature by separately arranging a sealed boat filled up with a raw material of a group III element and another raw material of a group V element and passing an introducing pipe for introducing the vapor of the group V element through the partition between the boat and the raw material of the group V element, and then, controlling the temperature of an area containing the partition, entrance of the introducing pipe, and group V element to a value lower than a specific value. CONSTITUTION:A raw material 9 of a group V element vaporized by sublimation enters an introducing pipe 5 from its entrance and reacts to another raw material 2 of a group III element in a boat 1, resulting in the solution of a III-V compound semiconductor. When the solution is solidified by gradually lowering the temperature of the solution from one end of the boat 1, polycrystalline grains or single crystal of the semiconductor is obtained. At this time, the temperature of an area containing a partition 6, the entrance of the pipe 5, and raw material of the group V element is controlled to <1,050 deg.C so as to suppress the reaction between the raw material of the group V element and a sealed quartz tube. Therefore, the risk of the occurrence of such a case that SiO is introduced to the boat 1 through the pipe 5 and gets mixed in the semiconductor can be reduced.

Abstract: PURPOSE:To detect the distance between a traveling car and a wall surface with high accuracy by detecting an angle and elevation angle on a traveling plane to a spot light source. CONSTITUTION:A spot light source 1 is fixed at an optional position h0 on a wall surface O which is much higher than the height of a traveling car 2.

Filed: 1992-03-11
Abstract: PURPOSE:To enhance the response to changes in the temperature of cooling water of an absorption refrigerating machine responding to the control of the concentration of a absorbent solution and preventing the generation of freezing troubles. CONSTITUTION:A refrigerant storage chamber 13 and a valve 14 are installed in a refrigerant passage from a condenser 7 to a vaporizer 8 where the refrigerant storage chamber 13 is designed to store a refrigerant solution temporarily and the valve 14 is adopted to control the flow rate of the refrigerant solution which flows out from the refrigerant storage chamber 13. At the same time, a water level sensor 16 is installed in the refrigerant storage chamber 13 while a cooling water temperature sensor 17 is installed in an inlet of cooling water so as to control the valve 14 in such a fashion that the current water level may approach a target water level which is determined by the temperature of cooling water. Since the refrigerant is supplied with a targeted optimum concentration (water level in the storage chamber) of solution responding to the temperature of cooling water from the current cooling water temperature and the water level in the storage chamber and there is not control time lag as a result, it is possible to prevent the generation of freezing definitely and protect the cooling capacity from being degraded due to its excessively diluted solution.

Title: Production of magnetic recording medium
Inventor: WATANABE YUKIO
IPC: G11B5/845
Filed: 1988-04-12
Abstract: PURPOSE:To improve magnetic characteristics by covering horseshoe-shaped magnets for magnetic field orientation with superconductors. CONSTITUTION:A pair of the horseshoe-shaped permanent magnets 5, 6 are disposed to both sides sandwiching a nonmagnetic base by oppositely positioning the N pole and N pole and the S pole and S pole in such a manner that the magnets are symmetrical with the central plane of the base. The magnets 5, 6 are circumferential coated with the superconductors 7, 8. A magnetic field orienting device is so disposed on the outside of the magnets 5, 6 that the direction of the magnetic field between the N pole and the S pole coincides with or approaches the recording direction of the resultant magnetic recording medium. The orientation treatment is executed by impressing the DC magnetic field to the magnetic coating compd. coated film prior to solidification by drying. As a result, the wasteful leak magnetic fluxes between the N and S poles are substantially eliminated and the effective use of all the magnetic fluxes for the orientation is enabled. The magnetic characteristics such as residual magnetic flux and squareness ratio are improved.
