Title: High-frequency ignition apparatus for internal combustion engine
Inventor: ENDOU HIROSHI
IPC: F02P15/12
Filed: 1981-06-11
Abstract: PURPOSE:To provide an engine ignition apparatus, capable of igniting and burning lean  air-fuel mixture in a reliable method under various operational conditions of engine, by  applying a high energy of superhigh-frequency waves to ignition plugs for a short  while in synchronism with the ignition timing of cylinders. CONSTITUTION:Superhigh-frequency energy is distributed by a superhigh-frequency distributor and applied to an ignition plug 16 via each transmission line 20 and coaxial- line connector 70. The ignition plug 16 is formed with a tapered section 79 of a length  l on the inside of its outer conductor 76 extending from a position near a hexagonal  nut portion 78 toward a discharge part 80. Here, the impedance matching is achieved  by selecting the length l to be equal to or greater than the wave length of the superhigh-frequency waves. Further, the outer conductor 72 of the connector 70 and that of  the ignition plug 16 have an equal inner diameter D, and the inner diameter d1 of the  outer conductor 76 at the discharge part 80 is selected to be far smaller than D. With  such an arrangement, when superhigh-frequency energy is applied to the discharge part  80, electric discharge is produced at the part by dielectric breakdown caused by the  high voltage, and a strong spark is produced by applying energy of about 200mJ in a short while.

Title: Chip type electrolytic capacitor
Inventor: SEKIYA KAZUO
IPC: H01G9/004
Filed: 1989-04-07
Abstract: PURPOSE:To improve the yield and the production efficiency at the time of manufacturing by constituting the columnar type part of a resin case accommodating a capacitor main body, in a taper type wherein the bottom part is narrowed, and the aperture part is wide and slightly larger than the diameter of the capacitor main body. CONSTITUTION:The columnar part 13c of a resin case 13 accommodating a capacitor main body 13 is constituted in a taper shape wherein the bottom part is narrowed and the aperture part is made wider and larger than the diameter of a capacitor main body by 0.05mm or more. When a chip type electrolytic capacitor is manufactured, the chattering of a product can be eliminated, because the bottom part diameter of the columnar part 13c of the resin case 13 accommodating the capacitor main body 11 is almost equal to the diameter of the capacitor main body 11. Since the diameter of the aperture is larger than that of the capacitor main body 11 by 0.1-0.2mm, the capacitor main body 11 does not collide with the resin case 13 at the time of manufacturing. Thereby the yield and the production efficiency at the time of manufacturing can be improved.

Abstract: PURPOSE:To miniaturize the device, control temperature easily, and record and delete information stably by controlling driving signals for giving recording and deleting energies from an energy giving means so as to be supplied irregularly and intermittently within a cycle to form one dot. CONSTITUTION:When information is to be recorded, temperature of an object picture element, i.e., a heat generating resistor corresponding to mark dot is raised to a temperature where temperature of a recording layer 28 rises to a white opaque temperature area regardless of an old image 32, and excitation is controlled to be done by a basic pulse Pb having numbers corresponding thereto. When the information is to be deleted, temperature of an object picture element, i.e., a heat generating resistor corresponding to space dot is raised to a temperature where the temperature of the recording layer 28 rises to a transparent temperature area regardless of the old image 32, and excitation is controlled to be done by the basic pulse Pb having numbers corresponding thereto. As a result, at the same time that the old image 32 is deleted, an overwrite recording for forming a new image 33 can be realized easily and stably.

Title: Multi air-conditioner
Inventor: YAMAKAMI KATSUJI
IPC: F25B13/00
Filed: 1996-03-19
Abstract: PROBLEM TO BE SOLVED: To prevent poor lubrication or seizure of compressor by turning ON a high head changeover switch when the difference in installation height between an indoor machine and an outdoor machine exceeds a specified height to increase a lower limit frequency of an inverter by a predetermined frequency. SOLUTION: A high head changeover switch 25 is turned ON when the total differences in installation heights, at the time of installing air conditioner, between indoor machines A, B and outdoor machine O exceed a specified height, for example 20m. When a signal is inputted from the switch, a frequency determination means 24 forcibly increases a lower limit frequency of an inverter 17 by, for example 12Hz, i.e., to 28Hz. As a result, the number of revolution of a compressor 1 and amount of circulating refrigerant is increased as compared to the number of revolution and amount of circulation refrigerant when the switch is OFF, and hence it becomes possible to push up a liquid refrigerant from the machines A, B to the machine O. Consequently reduction in the amount of liquid refrigerant and circulating oil, can be avoided.

Title: Writing and erasing methods, and ink and eraser to be used for same
Inventor: NAKAMURA TAKASHI
IPC: C09D11/17
Filed: 1998-03-18
Abstract: PROBLEM TO BE SOLVED: To perform a complete erasing, and also eliminate a peripheral contamination due to dust or the like by a method wherein a writing is performed by using an ink wherein one kind or more of dyes selected from methine dyes and azo methine dyes, are dissolved with water, and the written images are erased by an eraser containing at least one kind of reducing agent and water. SOLUTION: When a writing is performed on a writing board having an ink receiving layer such as a white board, an ink wherein one kind or more of dyes selected from methine dyes and azo methine dyes are dissolved with water, is used. In the meantime, an eraser which is used as a set with the ink, contains a reducing agent and water, and by wiping off the written images by the eraser, the dyes which form the images in the ink receiving layer react with the reducing agent, and disappear, and at the same time, the dyes move into the eraser. By this method, in either case of before or after a usage, the functional part of the eraser does not induce a coloring by sticking to hand, and when the ink is adhered, the ink can be easily washed away with water.
