Title: Optical transmission device
Inventor: TANEI HEIKICHI
IPC: G02F1/29
Filed: 1985-02-27
Abstract: PURPOSE:To decrease optical-axis adjustment positions by allowing a liquid- crystal optical switch part to switch the propagation direction of light between the same and opposite directions. CONSTITUTION:Trapezoidal glass plates 8 and 9 whose refractive index is 1.75 are placed having electrode surfaces opposite each other and a liquid-crystal material 6 is charged with spacers 10 of 5mum in thickness between the glass plates to manufacture a liquid-crystal cell structure. Long axes of liquid-crystal molecules are oriented by the effect of an SiO2 film in parallel to the transparent electrode surfaces and at right angles to the paper surface. The liquid-crystal material uses nematic liquid crystal which has refractive indexes ne=1.75 and no=1.49. When no voltage is applied between the transparent electrodes 11, light entering the liquid-crystal switch part from a receiving optical fiber 4 is reflected totally by the interface between a transparent electrode and a liquid- crystal film to reach a transmitting optical fiber 4'. When a proper voltage is applied between the transparent electrodes 11, on the other hand, the long axes of the liquid-crystal molecules are oriented at right angles to the transparent electrodes, so light projected by a light emitting element 20 reaches the transmitting optical fiber 4'.

IPC: G06F1/18
Filed: 1990-02-19
Abstract: PURPOSE:To surely prevent erroneous connection by confirming the coincidence of each I/O bit train between an input/output device and a main body. CONSTITUTION:An I/O bit train bI with the bit arrangement peculiar to an input/output device 2 is generated, and the bit train bI is sent to the main body 1 side as soon as a connector 3 is connected via the AND logic with the ON/ OFF signal from the connection confirming switch 4 of the connector 3. The connector 3 has the switch 4 to constitute a signal control mechanism. The I/O signal control register 6 of a main body 1 has the I/O type judging bit train bM consisting of the device type judging bit train b1 corresponding to the normal type of the devices 2 and the device number judging bit train b2 to distinguish the devices 2 of the same type, and it judges the bit train bI and sends a necessary signal to an I/O controller 7. The controller 7 opens the gate of a buffer group 8 via a flag register 11 turned on or off by the input/output command from a CPU and sends the port connection signal Sp of an I/O control device 12 only when the device coincidence signal SI from the register 6 is sent.

IPC: B41J11/70
Filed: 1978-03-31
Abstract: PURPOSE: To perform ordering of recording paper after having been taken out smoothly and rapidly by perforating a series of recorded recording paper in the specified positions.  
     CONSTITUTION: Writing and picture information subsequently inputted by a recording head 3 is recorded on the recording paper 1a supplied from roll recording paper 1. After it has undergone developing and fixing, it is transferred to a perforation  device 7. The device 7 puts perforations on the recording paper 1a based on the  signal indicating the boundary for each one sheet of the writing and picture information having been continuously recorded on the recording paper 1a. The signal  indicating the boundaries is drawn out by counting the pulse signals synchronized  to the feeding of the recording paper and calculating the recording paper transfer  distance or by other means. The recording paper 1a having been perforated is  sent to a stacker 8 and are folded at the perforated positions and is stored. Thereby, the recording paper after having been taken out may be ordered smoothly and  rapidly.

Title: Razorsigma edge
Inventor: ODA TAKESHI
IPC: B26B19/04
Filed: 1978-03-29
Abstract: PURPOSE: To improve the skin touch by forming several skin pressing edge pieces on the fixed outer razor's edge of a trimmer type electric shaver.  
     CONSTITUTION: Every third piece or so of edge pieces 4 of fixed outer razor's edge 1, skin pressing edge pieces 4a with larger width b or larger thickness t are formed. When the outer edge 1 touches the skin, the contacting pressure between other edge pieces 4 and the skin is reduced because these larger skin pressing edge pieces 4a will press the skin exclusively, and hairs can be cut short by other edge pieces 4 and at the same time better skin touch is obtained. Furthermore, thickness t of other edge pieces 4 can be made thinner to improve the cutting quality of the shaver.

Abstract: PURPOSE:To prevent front wheels from slippage by judging the presence of slip of wheels to increase the damping force of a damper for a front wheel suspension system and reduce same for a rear wheel suspension system when the slippage takes place and the acceleration condition is judged to be present. CONSTITUTION:In running of a vehicle, the rotational speed of front and rear wheels is detected by a rotation sensor 51, and whether or not the difference between both rotational speed is larger than a specified value is judged in a low mu road judging means (slip judging means) 52. When said difference is larger than the specified value, the slip is judged to take place, i.e. the vehicle is judged to be travelling on the low mu road (road having small coefficient mu of friction between timer and road) so that the ON signal output is generated. On the other hand, acceleration condition is judged from the signal of an acceleration sensor 54 by an acceleration condition judging means 55. And when the acceleration condition is judged to be true, the ON signal output is generated to a damper controlling means 56 according to the output signal of said means 52 and AND so that the damping force of a damper is increased.

Title: Control method for electric vehicle

IPC: B60L1/00
Filed: 1988-02-23
Abstract: PURPOSE:To smooth the load current of substation and to reduce the capacity thereof, by controlling throw-in of various electrical machinery corresponding to current consumption under powering. CONSTITUTION:When temperature information fed from a temperature sensor has a value exceeding over a set value, a central station 5 produces a throw-in command for an electrical machinery 9 (a cooler in this case). If an operational command C is not a powering command and current consumption of main motor is low, a control command E is turned ON at the time point when the throw-in command is turned ON, thus driving the electrical machinery 9. When the value of the temperature information drops below the set value, the throw-in command is turned OFF to stop the electrical machinery 9. If the operational command C is a powering command, the control command E is turned OFF even if the throw-in command is turned ON thus turning the electrical machinery 9 OFF forcibly.
