Title: Preview device for single lens relex camera
Inventor: OGI MIKIO
IPC: G03B19/12
Filed: 1996-11-19
Abstract: PROBLEM TO BE SOLVED: To reduce time lag till shutter traveling in the case of normal releasing by reversely rotating one rotation cam gear in a range where only diaphragming operation is performed without raising a mirror up when a preview switch is turned on. SOLUTION: When a mirror box mechanism 20 is on an original position and a motor 12 normally rotates, the cam gears 25 and 26 rotate in a positive direction once, so that the diaphragming of a diaphragm from an open position to a position for a set diaphragm value, the rising of the mirror 55, the shutter traveling, the falling of the mirror 55, and diaphragm reset from the diaphragming position to the open position are sequentially caused. When the motor 12 reversely rotates to rotate the gears 25 and 26 in a reversely rotating direction, the diaphragming operation from the open position to the position for the set diaphragm value is caused first. That is, the operation lag between the diaphragm and the mirror 55 is set to be caused after the shutter traveling in the release operation.

IPC: F24H1/10
Filed: 1991-11-25
Abstract: PURPOSE:To so control an output hot water temperature as to always maintain its output hot water temperature characteristics in high response irrespective of various variations in available conditions of a hot water supplying apparatus. CONSTITUTION:A temperature of hot water from a mixing valve 60 of a gas instantaneous hot water heater is detected as an output hot water temperature by an output hot water temperature sensor 90c. A microcomputer 100 calculates an output hot water amount in response to the detected result of a flowrate sensor 70 for a supply water amount to the heater. The microcomputer 100 so proportionally differentiates a mixing degree of the valve 60 that the output hot water temperature of the hot water is arrived at a set temperature in response to a variation in the detected output hot water temperature. The calculated mixture degree is corrected by a fuzzy inference responsive to the variations in the detected output hot water amount and temperature, and the mixture degree of the valve 60 is controlled toward the corrected mixture degree.

IPC: G11B5/31
Filed: 1993-11-17
Abstract: PURPOSE:To provide the process for production of the coil layers for a thin-film magnetic head capable of improving the withstand voltage between the coil layers and magnetic pole layers while assuring the prescribed number of turns. CONSTITUTION:A photoresist 5 of a positive type of a prescribed thickness is applied atop the first insulating layer 1.

Abstract: PURPOSE:To eliminate a part of an adhesive and a protective film after removal of a protective sheet by installing a buffer layer between the adhesive and the protective sheet. CONSTITUTION:A buffer layer 4 is installed between an adhesive 3 and a protective sheet 5. Thanks to this layer, the force which is exerted to a silicon substrate 1 by a grinder 7 is absorbed by the buffer layer 4 between the protective sheet and the adhesive 3; the adhesive 3 does not adhere excessively to a protective film 2; as a result, the adhesive 3 is not deteriorated or hardened. Accordingly, when the protective sheet 5 is stripped together with the buffer layer 4 after completion of a grinding process of the reverse face, a residual substance of the adhesive does not remain on the protective film 2; it is possible to completely remove the protective layer from the semiconductor substrate 1 if the protective film 2 is removed by an ashing process using a gas of oxygen or the like.
