Title: Magnetic disk device
Inventor: TANGAMI KEIZOU
IPC: G11B33/12
Filed: 1982-05-10
Abstract: PURPOSE:To prevent erroneous writing or reading and the damage of a disk, by plating with a magnetic material to a magnetic disk stored in a sealed case, and providing a deoxidizing agent in the hermetically sealed case or a breathing vent hole. CONSTITUTION:When a plated disk 1 is turned for writing or reading, the gas in a hermetically sealed case circulates in directions of arrows A, B, C, D and E. Meahwhile the dust is eliminated through a filter 5. At the same time, the increase of pressure due to a rise of the internal temperature is controlled through an air ventilating hole 6. When the revolution of the disk 1 stops after the writing or reading is through, the external air flows into the case owing to a reduction of pressure due to a fall of temperature within the case. In this case, the dust, the moisture and the oxygen are eliminated by means of a filter 7, a dehumidifying agent 12 and a deoxidizing agent 13 respectively. Then only an inactive gas flows into the case. Thus erroneous writing or reading and the damage of a disk are eliminated.

Filed: 1988-04-01
Abstract: PURPOSE:To contrive the stop of rotation of lens and to prevent a lens holder from slipping off at the time of focusing by fitting a lens holder in its projections and the groove of a helicoid member at the time of incorporating the lens holder into the lens holder supporting member. CONSTITUTION:In order to assemble the title device, the lens holder 22 is incorporated into the inside diameter of the holder supporting member 23 while deforming the projections 22a and 22b to be fitted in the inside of the device. When the lens holder 22 rotates, the projection 22a fits in the groove part 21a of the female helicoid member 21. Thus, even if the holder supporting member 23 turns at the time of focusing, the lens holder 22 does not rotate so that a lens part with a prism 24 can be used without adjusting every time. Also the projection 22b of the lens holder 22 serves as a stopper at the time of replacing the lens 24, and the projection 22a does not slip off the groove 21a of the female helicoid member 21. Therefore, the function of stopping rotating the holder 22 is maintained.

Title: Engine ignition timing controller
Inventor: HOSHI KOUICHI
IPC: F02P5/10
Filed: 1981-05-22
Abstract: PURPOSE:To make it possible to obtain a proper timing control angle commensurate to water temperatur, by switching the intake and seal of atmospheric  pressure or negative pressure (suction) into main and subdiaphragm chambers,  according to the temperature condition of an engine. CONSTITUTION:In the case where a temperature of cooling water is below the first temperature, a temperature feeler valve 20 closes a port 21, connecting 23 and 24 through and a temperature feeler valve 26 opens a port 28, connecting 27 and an atmosphere intake ports 29 through, while a temperature feeler valve 43 closes 44, causing negative pressure from a port 36 to be sealed only in a main diaphragm chamber 12, thus a fixed timing control is attainable. Between the first and second temperatures, the temperature feeler valve 20 only gets switched, leading atmopheric pressure into the main diaphragm chamber 12 and negative pressure into a subdiaphragm chamber 13 respectively, thus a relatively small, fixed timing control is carried out. On the other hand, when exceeding the second temperature, temperature feeler valves 26 and 43 are both actuated, leading atmospheric pressure into the subdiaphragm chamber 13 and negative pressure into the main diaphragm chamber 12, thus timing control corresponding to the negative pressure can be done.

IPC: H04N17/00
Filed: 1992-02-28
Abstract: PURPOSE:To provide a method of accurately testing the deterioration or the like of an image in a video device. CONSTITUTION:A three-dimensinal test signal including a background component having variable complexity and foreground component (e.g. a color, bar, a linearity signal, pulse and bar signals, and a multi-burst signal) inserted into a known position of the background component is generated and supplied to the video device 14 and the foreground component in an output signal from the device 14 is measured. In this case, a three-dimensional test signal including a background component capable of three-dimensionally and optionally changing complexity and a foreground component obtained by inserting a known test signal into the background component is used. Since a test can be executed by a test signal having much more information capacity as compared with a test based upon only a convensional test signal, a test based upon information capacity matched with usually broadcasted image information can be attained and a test more accurate than a convensional one can be attained.
