Abstract: PURPOSE:To display the information at real time in an optional position in a finder visual field by overlapping light rays of a subject image on a screen with light rays which go into a pentagonal roof prism from a display means and carrying out observation through an ocular. CONSTITUTION:A triangular prism 9 is joined to a flat reflecting face 102 besides a roof reflecting face 101 of a pentagonal roof prism 6.

Title: Clothes dryer
Inventor: KAWAI TETSUO
IPC: D06F58/28
Filed: 1989-05-24
Abstract: PURPOSE:To improve safety by immediately stopping operation regardless of a temperature difference change rate when it is judged that the temperature of a second temperature sensor fitted near a heater is higher than a prescribed value. CONSTITUTION:A temperature detecting means 12 detects the temperatures of first and second temperature sensors 8 and 10. When air is not passed through a heater part 7 by the abnormality of a thermal exchange fan 3, a temperature a' of the temperature sensor 8 does not rise up so much but a temperature b' of the temperature sensor 10 rises rapidly. A microcomputer 13 compares the temperature b' of the temperature sensor 10 with a prescribed value K3 by a comparing means 16 and in the case of b'>K3, the operation is immediately stopped regardless of the temperature difference change rate. Thus, damage is prevented to clothes and parts near the heater and safety is improved.

Filed: 1983-07-20
Abstract: PURPOSE:To detect the down-edge of a current flowing to the primary winding of a transformer by varying the state of a resistance coupling type OR circuit constituted of a resistance and a Josephson device when said current is reduced to zero. CONSTITUTION:When an input signal current flowing through the primary winding of the transformer 101 increases from zero toward a direction 121, the Josephson device 103 in the detecting circuit of a vibration-proof type resistance Josephson device coupling down-edge is switched to a resistance state at the time point when a branch current flowing through the Josephson device 103 of the secondary current in a direction 122 induced by the secondary winding reaches a threshold level, and attenuates the current of the secondary winding of the transformer 101. Subsequently, when the input signal current is reduced to zero from a prescribed value or the maximum value, it is switched to a resistance zero state, its state is held and a resistance coupling type OR circuit 102 is switched. A resistance 105 connected in parallel to the secondary winding operates as a damping resistance in case the Josephson device 103 is switched to the resistance state and the current of the secondary winding is attenuated, and has an operation for eliminating vibration in case the current is attenuated, shortening an attenuation time, and operating the circuit at a high speed.

Title: Maintenance driving circuit for thin film el element attached with memory
Inventor: ISE MASAHIRO
IPC: H04N5/70
Filed: 1977-11-01
Abstract: PURPOSE:To ensure performance of the large current switching via a simple pulse generator circuit by controlling the voltage application via the thyristor using the sine wave voltage as the power source of the maintenance driving. CONSTITUTION:Power supply transformer 80 applies the sine wave AC voltage featuring the maintenance voltage to line A and C. When the AC boltage is O, maintenance voltage T1 is generated to turn on thyristor 21 and 41 at one time. Thus, the current is flown to thin film EL element 10, and thyristor 21 and 41 are turned off automatically when the current flowing to element 10 becomes O. In this instant, voltage T2 is applied to thyristor 52 via transformer 53 to turn on thyristor 52, and the backward voltage is applied to element 10. As a result, the 1-period sine wave voltage and current are supplied to element 10. In such way, the sine wave voltage is used as the power source for the maintenance driving, and the application of the voltage is controlled by the thyristor. Thus, the large current switching can be carried out via a simple pulse generator circuit.

Abstract: PURPOSE:To enable detection of carbon monoxide and the like filled up in either of inner barrels of adjacent heat exchangers by a commonly-used gas sensor by constructing a communication passage making said inner barrels communicate with each other and by installing the gas sensor in the communication passage. CONSTITUTION:A communication passage 3 is constructed between inner barrels 2a and 2b of a hot water feeder with an additional heating function provided with a heat exchanger 1a for feeding hot water and a heat exchanger 1b for additional heating.
