Title: Multicolor electrophotographic transfer method
Inventor: AOKI KATSUHIRO
IPC: G03G15/01
Filed: 1987-08-05
Abstract: PURPOSE:To make the transfer efficiency in respective transfers maximum in case of plural times of transfer and to reduce the optical attenuation of a photosensitive body by irradiating the photosensitive body with a light whose wavelength is changed according to the spectral reflection characteristic of toner before transfer and executing destaticization. CONSTITUTION:A pretransfer destaticizing lamp 18 which irradiates the photosensitive body 4 with the light beam before transferring is installed by utilizing a free space and a filter 19 is interposed between the pretransfer destaticizing lamp 18 and the photosensitive body 4. Just before a developed image on the photosensitive body 4 is transferred on a transfer sheet 8 with the action of a transfer charger 15, the pretransfer destaticizing lamp 18 irradiates the photosensitive body 4 with the light through the filter 19 and the electric potential of the photosensitive body 4 before transferring can be lowered. Thus, the transfer efficiency at every color can be made maximum and the optical attenuation of the photosensitive body can be reduced by selecting colors at every color.

Title: Radio transmitter-receiver
Inventor: SHIMIZU HIROYUKI
IPC: H04B1/40
Filed: 1989-07-31
Abstract: PURPOSE:To reduce the crossmodulation fault in a receiver and to prevent the deterioration in a low noise element of the 1st stage of the receiver by attenuating a transmission signal leaked from a high output transmitter to the receiver via a multicoupler with an isolator further. CONSTITUTION:In the case of reception by the receiver 2, the reception signal is received via an antenna 10, a multicoupler 8 and an isolator 4. The isolator 4 has the characteristic of reception frequency band having frequencies of a1-a2, the forward passing loss is a low loss pass area and a reverse passing loss is the attenuation area. Thus, the receiver 2 receives the reception signal from the isolator 4 almost without any loss but a reflection signal or the like from the receiver is attenuated. In the case of transmission from a transmitter 6, a radio wave radiates via the antenna 10 and the multicoupler 8, and the transmission signal from the transmitter 6 is leaked to the isolator 4. However, the isolator 4 shows the characteristic of the transmission frequency band of frequencies a3-a4 and the forward and reverse passing loss is in the attenuation area. Thus, the leakage of the transmission signal to the receiver 2 is almost eliminated.

Title: Safety device for combustion
Inventor: OKAMOTO HIDEO
IPC: F23N5/24
Filed: 1985-09-07
Abstract: PURPOSE:To make it possible to check a trouble in a relay dependently on whether or not an ignitor is beforehand driven when igniting a burner by constituting a drive circuit for an ignitor so that only its drive circuit is closed when a relay is normal. CONSTITUTION:The ignition operation for a burner 2 is made by an operation element, and at the same time an electromagnetic safety valve 1 is pushed and opened. Further, a change-over switch 18 is changed over to the side of a dry battery 19 and the charged current flows to a condenser 20, and the current flows to a relay 21 and the relay 21 is energized and operated, closing its contact point 21a. The current from a dry battery 19 flows to a change-over switch 18, a reset relay 8, an ignitor 17 through said contact point 21a, driving the ignitor 17 and igniting a burner 2. Incidentally in this case, since the ignitor 17 is not driven unless a current does not flow to a reset relay 8 which is a relay for opening a drive circuit 6, it is possible to check whether or not said reset relay 8 has a cut wire trouble by discriminating whether an ignitor 17 is driven or not.

Filed: 1990-07-25
Abstract: PURPOSE:To eliminate a drying of a room during a heating operation and get a comfortable heating stage by a method wherein an electrical heating device is comprised of a thermal radiation panel surface, a hot air heater device utilizing a ceramic heater and a humidifying device for heating water and discharging water vapor, and then a hot air blowing port of the hot air heater, the thermal radiation panel surface and the humidifying blowing port for the humidifying device are disposed from a lower position to a higher position in this order. CONSTITUTION:A thermal radiation panel surface 6 is not red heated with a thermal radiation of infra-red ray of long waver length in a range from 150 deg.C to 450 deg.C and no firing of combustibles may occur. A hot air heater device 5 has a ceramic heater 2. The ceramic heater has a positive resistance temperature characteristic, a superior fast heating characteristic and a high safety characteristic. Heating only with the thermal radiation panel surface 6 causes a part higher than a substantial central part of a main body 1 to be heated and then a lower part is not heated well. When the thermal radiation panel surface 6 and the hot air heater device 5 are used together, an entire room is heated and a drying condition may also be hard to occur. At this time, when a humidifying switch 15 is turned on, water vapor 17 is dispersed by the humidifying device 10 under an action of convection flow 18 at the thermal radiation panel surface 6 and natural ascending of air and the water vapor 17 expands over an entire room.

Filed: 1999-07-12
Abstract: PROBLEM TO BE SOLVED: To brake a golf cart by a brake motor and assuredly stop it after a prescribed time when it is detected that the golf cart moves backward upon stopping the golf cart by a manual operation. SOLUTION: In accordance with the start of an assist brake control, it is decided whether or not an accelerator pedal is turned OFF in step S1. When the accelerator pedal is turned OFF, a procedure advances to step S2. When the accelerator pedal is turned ON, it is decided whether or not a backward movement is detected in step S3, When the backward movement is detected, it is decided whether or not a backward movement state continues for 0.5 seconds in step S4. When the backward movement state continues for 0.5 seconds, the backward movement speed of a cart is detected in step S5. Then, the energizing duty of a brake motor is determined in accordance with the backward movement speed of the cart in step S6. In step S7, the brake motor is turned ON to apply a braking force to a brake drum.  Then, in step S8, a parking brake is automatically turned ON after prescribed time (about one second) to assuredly stop the golf cart and finish the control in step S9.
