Filed: 1994-06-08
Abstract: PURPOSE:To eliminate a disturbance factor and improve the detection precision by photodetecting reflected light from plural areas and outputting a detection signal when the arithmetic value based upon the quantity of reflected light and the reference quantity of reflected light is larger than a specific value in any one area. CONSTITUTION:This device is equipped with a light projecting means 1 which projects light on plural areas and a photodetecting means 2 which photodetects the reflected light from the respective areas. Then an arithmetic means 3 calculates the differences between the quantities of reflected light in the respective areas at a specific time and the reference quantities of reflected light determined by the areas from the output results of the quantities of reflected light of the photodetecting means 2, finds the mean value of the differences, and calculates the sums of the mean value and the reference quantities of reflected light of the respective areas and the differences between or the ratios of the mean value and the quantities of reflected light of the areas at specific intervals of time. When the difference or ratio exceeds the specific value in any one area, a decision means 4 outputs a detection signal. Consequently, even if the quantity of reflected light varies, the entry of a human body, etc., can surely be detected.

Title: Gas cutoff valve
Inventor: OHASHI NORIYOSHI
IPC: F16K31/06
Filed: 1988-05-24
Abstract: PURPOSE:To obtain reliability without malfunction due to external impact by providing a collar part in the periphery of a core piece and guiding a permanent magnet by a sheet metal pressing work. CONSTITUTION:At the time of abnormality, when an electromagnetic coil 6 is instantaneously energized so as to generate a magnetic field opposite to a permanent magnet 2, a magnetic force is generated by the electromagnetic coil 6 so as to reduce attraction force between a core piece 3 and a plunger 9. A magnetic flux in this case passes the plunger 9, the core piece 3, the collar part 3a of the core piece 3, a yoke 1 and yoke 7. Accordingly, when viewing from the coil side, magnetic resistance is reduced by the part of the collar part 3a of the core piece 3. Consequently, since the magnetic flux generated by the coil 6 passes the attracting face of the plunger 9 and the core piece 3 more than when there is not collar part 3a of the core piece 3, a difference between the attraction force when a current value is 0 and the attraction force in an operating point can be increased. The core piece 3 has a form capable of being pressed.

Title: Personal identification system
Inventor: MAEDA MUNEKAZU
IPC: G06Q40/02
Filed: 1989-05-19
Abstract: PURPOSE:To make it difficult for a third person to decode a personal identification number from inputting operation by decoding the inputted personal identification number from key-inputted data and the random combination of numerals of an indefinite number of digits generated by a random numeral generator. CONSTITUTION:At first, a system displays the random combination of numerals of the indefinite number of digits generated by the random numeral generator 3c on a display device part 3b, and a bearer of a card key-inputs his own personal identification number after inputting the numerals being displayed. After that, the system displays again the random combination of numerals of the indefinite number of digits on the display device part 3b, and the bearer of the card key-inputs the numeral being displayed. An input data decoding means 3d removes the random numerals of the indefinite number of digits from the front and the rear of the key-inputted data, and decodes the personal identification number. Besides, since the display device part 3b is positioned at a position sinking deeper than a front face, it is made incapable of being seen by the third person. Thus, it becomes difficult for the third person to decode the personal identification number from the inputting operation of the personal identification number.

IPC: H01L21/316
Filed: 1982-07-21
Abstract: PURPOSE:To obtain an insulated and isolated Si island by a method wherein a poly Si is superposed on a single crystal Si substrate via an Si3N4, and the Si substrate is partially changed into porous state and oxidized. CONSTITUTION:The Si3N4 11, SiO2 12 (omissible), and poly Si 13 are deposited on the N type single crystal Si substrate 10. After polishing the Si substrate 10, P layers which reach the Si3N4 are provided by applying an Si3N4 mask 14. The exposed single crystal Si and the lower side thereof are changed porous down to the Si3N4 by anodic formation in HF. Successive oxidation causes to form SiO2 15 with approximately the same area as the porous parts, and accordingly single crystal islands 10' are completed. This constitution unnecessitates V-grooves, therefore the orientation of crystal surfaces of the substrate is not restricted, and then element formation can be performed by utilizating every crystal surface. Since grooves are not formed, the generation of warpage and damage decreases.

Filed: 1983-07-12
Abstract: PURPOSE:To enable the operation of a timer simply by making the setting of the timer for starting and ending the operation of the timer operable so simply as to eliminate the need for remembering the way of operation. CONSTITUTION:For example, when recording is to be done ''from 9:00 to 10:54'', ''9'' is inputted into a buffer 4 with an input control circuit 2. Then, when ''from'' is inputted, output of the buffer 4 is inputted into a register 6 and the buffer 4 is cleared by output of the input control circuit 2. Subsequently, ''1054'' is inputted being shifted from the left to right of the buffer 4 with the keying thereof. When ''to'' is inputted, ouput of the input buffer 4 is inputted into an end time register 7 through the output 2b of the input control circuit 2. The hour contents of the end time register 7 give ''10'' and the minute contents ''54''. This enables the inputting of information for setting a timer, for example, the desire to record ''from 9:00 to 10:54'', in the order of words whereby the operation of the timer can be done so simply as to eliminate the need for remembering the way of operation.
