Title: Electrical vehicle selector signal device
Inventor: KOSHIZAWA TOSHIBUMI
IPC: B60L11/18
Filed: 1996-02-15
Abstract: PROBLEM TO BE SOLVED: To achieve proper response even when a push-button-type selector switch is used for a motor control device for drive which responds only when selector signals in an order corresponding to a specific range order to prevent erroneous operation. SOLUTION: A selector signal generation device 6 is included between a push-button-type selector switch 7 and a motor control device 2 for drive. When a target range is specified by the selector switch 7, the selector signal generation device 6 successively generates selector signals corresponding to each range from a range adjacent to the side in the target range direction of a current range to the target range and hence the push-button-type selector switch 7 can be adopted as a selector switch.

Title: Image forming device
IPC: G03G15/09
Filed: 1992-03-13
Abstract: PURPOSE:To minimize the disturbance of a previously formed toner image which is caused by a later developing device and to efficiently recover carrier. CONSTITUTION:On a photosensitive drum 11, a toner image is formed by the other developing device (not shown). The magnetic force of the main magnetic pole 62 of a magnet roll 45 is V-shaped so as to fall in the area where an electrostatic latent image is developed and rise on its both sides. Since a magnetic brush 65B does not exist in the part where it falls, developer 65 moves from one side of the main magnetic pole 62 to the other side and, at this time, the electrostatic latent image is developed. The napping of the magnetic brush 65B does not come into contact with the toner image, thereby its disturbance is suppressed and also carrier is efficiently recovered by the movement of the developer.

Title: Drying method for water drop adhered matter and apparatus therefor
Inventor: KOBA KAZUNORI
IPC: F26B3/22
Filed: 1996-03-12
Abstract: PROBLEM TO BE SOLVED: To prevent discoloring caused by reaction with oxygen in air by a method wherein a matter with water drops is immersed into a high temperature fluid layer of a water-absorbable granular material and water drops are absorbed into the granular material for drying the matter with the water drops to enable evaporating of water adhering to the matter completely in a very short time. SOLUTION: When mechanical parts etc., are dried after the washing thereof, hot air obtained from a hot air circulator 5 is introduced into a space below a drying chamber 2 and fluidized vertically in a layer of a granular material 4 to obtain a fluidized layer of the granular material 4 by adjusting the flow velocity of the hot air. The hot air is discharged from a space above a drying chamber 2 to be circulated through the drying chamber 2 again by a blower 11. In this process, the matter A2 with water drops is conveyed to a drier 1 from a washer 6 being hanging with a suspension jig 7 and dumped and immersed into a layer of the bulk solid material 4. Thus, the granular material 4 contacts the water drops of the matter A2 to absorb water while the water absorbed by the granular material 4 is evaporated by the fluidization of the hot air.

Title: Fluorescent lamp
Inventor: HASHIMOTO NOBORU
IPC: H01J61/42
Filed: 1978-05-09
Abstract: PURPOSE: To prevent the dielectric breakdown of a fluorescent lamp and the production of black spot thereon, by providing a transprent electro-conductive coating film on the inside surface of a fluorescent tube and coating a fluorescent substance of large grain size on said film.  
     CONSTITUTION: The transparent electrocuductive coating film (nesa film) 2 of tin oxide (S n O 2-x ) is coated on the inside surface of the fluorescent tube 1 of glass. The fluorescent substance 3 is coated on said film. Mercury gas and argon gas are filled in the tube, thereby manufacturing the nesa-type fluorescent lamp. The grain diameter of the fluorescent substance 3 is made larger 6 μm to increase the percentage of voids between the grains of the fluorescent substance. Discharge is caused through the voids. The higher the percentage is, the lower the effect of the discharge on the fluorescent substance is. The black spot is thus prevented from being produced on the fluorescent tube by breakdown discharge. If fine powder of tin oxide (S n O 2-x ) is blended in the fluorescent substance, the fine grains of the powder adhere to the surfaces of the grains of the fluorescent substance to raise the bonding property of the fluorescent substance with the coating film 2.

The acidic water is sent to a delivery pipe 1 of delivery tools A and the alkaline ionic water is sent to a discharge pipe 2. When one's hand is detected by a sensor equipped in the delivery tools A, the valve 31 is opened and the acidic water is delivered from the delivery pipe 1 into a washbowl 3 and the alkaline ionic water is discharged from the discharge pipe 2 into the washbowl 3.  In this way, the acidic water is neutralized by the alkaline water and hence, the drain metal tools of the washbowl 3 are prevented from corrosion.

IPC: G06F11/00
Filed: 1991-03-20
Abstract: PURPOSE:To prevent the breakage and the damage by burning of a device in an alarm detecting system by cutting off a unit power supply when a sensor is wrong connected. CONSTITUTION:A main power supply 2 is provided together with a power controller 3, a unit power supply 4, and a sensor 5 which detects the temperature abnormality of a device 6. The controller 3 receives a power application command from a host device while the power supply 2 is supplying the power to the controller 3 and the power supply 4. Thus the controller 3 gives a power application command to the power supply 4 to start the supply of power to the device 6 end the sensor 5 through the power supply 4. Then the controller 3 cuts off the power supply 4 when the abnormality of a signal line (the abnormality due to the wrong connection of the sensor 5 or the original abnormality) is detected by the sensor 5 connected to the controller 3.

Title: Braking hydraulic pressure control valve for double pipe
Inventor: MAEHARA TOSHIFUMI
IPC: B60T8/28
Filed: 1978-05-10
Abstract: PURPOSE: To compensate insufficient braking force of a braking hydraulic pressure control valve for a double pipe by stopping the operation of one braking oil system when one braking oil system fails to thereby apply the same braking hydraulic pressure to both the front and rear wheels.  
     CONSTITUTION: An a system valve mechanism opens or closes a passage 25 of communicating input and output oil chambers a 1  and a 2  with a valve body. A b system valve mechanism opens or closes a passage 30 of input and output oil chambers b 1  and b 2  with a ball 29. The hydraulic pressures of the master cylinders of both the a and b systems are transmitted through the passages 25 and 30 of the a and b system valve mechanisms to output oil chambers a 2  and b 2  to act against stepped piston 3 and control piston 8. When the a system valve mechanism malfunctions, the pistons 3 and 8 move rightwardly to normally use the passage 30. When the b system valve mechanism malfunctions, the passage 25 is normally opened. When one system fails, the other system does not control the braking oil pressure so as to thereby compensate insufficient braking force.

IPC: B29K101/10
Filed: 1986-03-13
Abstract: PURPOSE:To prevent the occurrence of a gap between a cavity and a molded body by moving the part of a mold so as to shrink the cavity, when high energy ray is radiated onto the hardening resin composition injected into the cavity of a mold and harden the resin composition. CONSTITUTION:A mold 1 is composed of a top force 2 and a bottom force 3, and a cavity 4 is formed in between the top and bottom forces. The window part 5 through which high energy ray can penetrate is provided on the top force 2. The window part 5 is composed of the first quartz glass plate 5a and the second quartz glass plate 5b, and the space between the first and the second quartz glasses becomes a cooling chamber 5c. In this process, while the hardening reaction of the composition is advanced by the radiation of high energy ray, the cavity 4 is caused to shrink so as to absorb the polymerization shrinkage of the composition. The shrinkage of the cavity 4 is achieved by energizing upward the bottom force 3 of the mold 1 with specified pressure, using the air cylinder of the molding device.
