Title: Image forming device
Inventor: OKANE AKIO
IPC: G03G15/08
Filed: 1986-12-04
Abstract: PURPOSE:To eliminate an image defect and to prevent the temperature in a machine from rising by providing a temperature detecting means which detects the developing device temperature of an image forming device, and interrupting image forming operation when the developing device temperature is higher than a set temperature and cooling the developing device by a cooling means during this period. CONSTITUTION:If the detected temperature of a temperature sensor 3 rises above the set temperature in continuous copying operation, the output signal 9 of a comparing circuit 8 rises to H to put a fan driving circuit 16, thereby operating a fan. The signal 9 and a signal 11 are both H, so the output signal 12 of an AND gate 10 is H, a delay circuit 13 operates and a signal 14 rises to H, and a controller 15 interrupts the image forming operation including electrostatic latent image formation and development. Then when the developing device 2 is cooled by the fan 4 until the detected temperature of the temperature sensor 3 drops to the set temperature or less, the output signal 9 of the comparing circuit 8 falls to L and the image forming operation is restarted. Consequently, troubles such as the blocking development of toner caused by a rise in the temperature of the developing device by a heat source are eliminated.

Title: Living body tissue coupling electrode
Inventor: ITO HIROYASU
IPC: A61N1/05
Filed: 1990-10-26
Abstract: PURPOSE:To easily and surely couple the living body tissue of a nerve cell, etc., by covering a conductive needle-like member with an insulating cover member, and providing an electric conduction part on the cover member. CONSTITUTION:In a state that an interval of a first electrode 11 and a second electrode 12 is large, a main body case 10 is subjected to moving operation in the direction as indicated with an arrow B. Subsequently, when Schwann cells of two pieces of nerve cells to be coupled are inserted and held by recessed parts 43 of cover members 42, a first electrode 11 and a second electrode 12 are brought close to each other by turning a micrometer 16 attached to the main body case 10. This operation is continued until two pieces of Schwann cells are bundled and brought into contact with each other between the respective recessed parts 43 of a first electrode 11 and a second electrode 12. Thereafter, by executing instantaneously turn-on/turn-off operations of a switch SW, a pulse voltage is applied between a first electrode 11 and a second electrode 12. In such a way, each Schwann cell is fused, but since a needle-like member 41 is obstructed by the cover member 42 and does not come into contact with the Schwann cell, the nerve cell is not flawed.

Title: Pwm signal generating system
Inventor: YANASE TAKAO
IPC: H03K7/08
Filed: 1988-11-15
Abstract: PURPOSE:To reduce noise of an inverter by employing a control signal having such period as integer times of the sample period of a processor thereby producing a PWM signal and improving the waveform. CONSTITUTION:Sample frequency (fs) is provided with upper limit of 3kHz and lower limit of 1.5kHz. The upper limit is determined by the processing capacity of a processor and the lower limit is determined by the control performance of a PWM inverter 1. In the three-phase inverter, the ratio between the control signal period and the sample period is set to a multiple of 6. By such arrangement, waveforms of three-phase output from the PWM inverter are equalized, and the positive and negative waveforms are made symmetrical. In order to employ the zero angle point of sinusoidal wave as an initial sample value, it is required to perform switching at integer time points of 60 deg.. By such arrangement, pseudo sinusoidal waveform can be made symmetrical.

Title: Target signal retrieving device
Inventor: FUJITA TOMOYOSHI
IPC: G11B21/08
Filed: 1987-11-17
Abstract: PURPOSE:To suppress oscillation in the tracking direction of mobile optical parts and to quickly perform retrieval by controlling mobile optical parts by an acceleration signal corresponding to the acceleration of movement of an optical pickup device at the time of moving the optical pickup device in case of retrieval. CONSTITUTION:Since a signal corresponding to the actual moving speed of an optical pickup device 1 which is obtained from a linear encoder 12 is generated from a decoder 15, the speed signal generated from a speed signal generating circuit 26 approximately coincides with the actual speed. Therefore, an acceleration signal approximating the actual moving acceleration of the optical pickup device 1 is generated from a differentiating circuit 27. Consequently, the acceleration signal corresponding to the moving acceleration of the optical pickup device 1 is supplied to a tracking coil 10 at the time of moving the optical pickup device 1 in case of retrieval. Thus, oscillation of an objective lens 5 is suppressed to increase the retrieval speed.

Abstract: PURPOSE:To prevent the decrease in the original density and to miniaturize the equipment by providing a polarization plate between a light source and an original and between the original and a read side respectively so that the polarized direction is made orthogonal thereto thereby cutting off a regularly reflected light. CONSTITUTION:A light lambda1 from a light source 1 passes through a polarized plate 11, becomes a light lambda2 having a polarized component in X direction only and is irradiated to an original face 2. The light lambda2 is reflected in the original face 2 and divided into a regularly reflected light lambda3' and a scattered light lambda3. The light lambda3, lambda3' are irradiated from the incident point of the light lambda2, enter the polarized plate 13, where the light becomes lights lambda4', lambda4 having only the Y direction component, they are collected by a lens 3 and the image is formed in an image sensor 4. Since the light lambda3' is a light having only the X direction component, it is cut off by the polarization plate 13 and not incident in the sensor 4. On the other hand, the light lambda3 is a random light, the Y component transmitting through the polarization plate 13 remains and density information is read by the sensor 4. The light source 1 and the sensor 4 are arranged closely, then the miniaturization of the entire equipment is attained.
