Title: Protection system for high voltage generating circuit
Inventor: SAKUMA TOSHIHARU
IPC: H04N3/18
Filed: 1990-09-28
Abstract: PURPOSE:To prevent adverse effect onto a circuit element connecting to a +B voltage by applying an output of a detection circuit detecting a high output voltage to a control circuit of a switching transformer circuit so as to turn off the output of the switching transformer circuit. CONSTITUTION:When a high output voltage of a flyback transformer circuit 2 exceeds a prescribed value, an output of a detection circuit 3 controls a control circuit 5 to turn off a DC output of a switching transformer circuit 4. Thus, the high output voltage of the flyback transformer circuit is turned off to be 0V and a +B power supply is 0V, then the flyback transformer circuit is not a load and then the +B power supply voltage rises and the possibility of applied a voltage in excess of the rated voltage to other connected circuit element is precluded. Thus, the adverse effect onto the other circuit is suppressed.

Title: Controller for flow rate valve
Inventor: SUZUKI YASUHIRO
IPC: F24F11/02
Filed: 1994-10-24
Abstract: PURPOSE: To prevent a valve from being fixed and to enable secure flow rate control by performing outputting to a high voltage valve driving circuit when the valve is opened but performing outputting to a low voltage valve driving circuit when the valve is closed. CONSTITUTION: When a flow rate valve 114 is opened, an open valve input from a valve open/close input part 100 is judged by an open valve judging part 115 inside a control part 1, a signal from a high voltage open valve output part 2 is converted to the driving waveform of a high voltage by a high voltage valve driving circuit 4, a motor 113 is driven corresponding to a requested aperture and the flow rate valve 114 is opened.  When closing the flow rate valve 114, a close valve input from the valve open/close input part 110 is judged by the open valve judging part 115 inside the control part 1, a signal from a low voltage close valve output part 3 is converted to the driving waveform of a low voltage by a low voltage valve driving circuit 5, the motor 113 is driven oppositely to the valve opening direction corresponding to a requested aperture, and the flow rate valve 114 is closed. Thus, since the input from the valve open/close input part 110 is judged by the control part 1 and the motor 113 is driven by the high voltage at the time of opening the valve or driven by the low voltage at the time of closing the valve, the valve can be opened by a small torque at the time of closing or a large torque at the time of opening.

Title: Optical beam detector
Inventor: TERADA YOSHITAKA
IPC: G11B7/13
Filed: 1990-09-27
Abstract: PURPOSE:To reduce in size an entirety, and to detect a timing of passing an optical spot by reducing in size a photodetector in which the spot of the beam is previously passed. CONSTITUTION:When a first photodiode PD12 is reduced in size as compared with a second photodiode PD22 (L12<L22), waveforms of optical currents I12, I22 and voltage levels V12, V22 corresponding thereto become as indicated by solid lines even in this case, its timing can be detected without influence of the peak value of the wave of the current, and the entire photodetector can be reduced in size. A photodiode indispensably has a junction capacity C. Thus, a delay occurs as indicated by a broken line. This delay amount is proportional to the size of the capacity. Here, the smaller the capacity is, the smaller the photodiode is reduced in size. Accordingly, a crossing point is slightly deviated and stopped from XA2 to XB2. Therefore, an accurate timing can be detected.

Abstract: PURPOSE:To enable low-loss coupling by providing a guide-pin elastic pressure member above where a guide-pin groove and a guide pin contact each other at the groove part of an upper plate. CONSTITUTION:An upper plate 4 formed of a material similar to a hard brittle material such as ceramics is joined with the upper part of a guide groove substrate 1 which is made of the hard brittle material and has an optical fiber guide groove 2 and the guide-pin groove 3 ground in the top surface and a groove part 5 covering the guide pin 10 positioned in the guide groove 3 of the guide groove substrate 1 is formed in the upper plate 4. Then the groove part 5 is provided with the guide-pin elastic pressure member 6 only above the center of the guide pin 10. A resin formation part 7 which is molded out of epoxy resin, etc., in one body is provided at the outer periphery of the joined guide substrate 1 and upper plate 4. Then the gap  el between the guide-pin elastic pressure member 6 and guide pin 10 is set to, for example, <=10mum, and consequently the molding resin does not flow to the groove part 5 of the upper plate 4, so that the guide-pin elastic pressure member 6 is formed above the guide pin 10.

Abstract: PROBLEM TO BE SOLVED: To obviate excavation of earth, and shorten a construction period by arranging pile-shaped footings under columns of a building unit of the lowest story. SOLUTION: Plural building units 1 are laterally and vertically joined together, and pile-shaped footings 31, 32 and 33 are arranged under columns 11 of a first floor unit 1 through installing stands 21 and 23, and a two-storied unit building A is constituted.

IPC: B65D39/06
Filed: 1994-09-27
Abstract: PURPOSE: To make a viscous fluid flow out of a flow-out port immediately after a container filled in with a liquid glue, a shampoo, or the like is inclined for use with respect to a container that is stood with a flow-out port showing up when it is out of use and inclined with the flow-out port showing down for making the viscous fluid flow out little by little when it is in use. CONSTITUTION: By providing an orifice 52, a container 11 is divided in the height direction into an upper small chamber 32 including a flow-out port 51 and a lower tank chamber 31. Furthermore, a dead weight 4 is provided in the small chamber 32. When the container is out of use, the dead weight 4 is guided by a guide means 15 to move downward to an orifice closing position 54 where the dead weight 4 covers the orifice 52 to restrict a flow rate of a viscous fluid flowing from the small chamber 32 down to the tank chamber 31 per unit time. When the container is in use, the dead weight 4 moves downward to a stopper position 53 apart from the orifice 52 until it is limited by a stopper means 6, thereby uncovering the orifice 52.

Title: Multicolor electrophotographic device
Inventor: HIRATA HIROSHI
IPC: G03G15/01
Filed: 1993-09-24
Abstract: PURPOSE:To prevent picture quality from being degraded by the scattering of a black toner so as to reproduce sharp black images in a multicolor electrophotographic device which overlays toner images of plural colors on a photoconductor to transfer the images onto paper at a time. CONSTITUTION:A black toner image is set to be formed prior to a multicolor toner image, and a magnetic toner with an electrical resistance value of 10<14>OMEGA.cm or more is used as the toner stored in a developing device for black. Also, a magnetic toner whose electrical resistance value is almost equal to that of the material of a resin binder, with colorants dispersed in the resin binder, may be used as the black toner. Therefore, a charge in a toner layer is prevented from migrating toward a photoconductor as it is attracted by a charge of the opposite polarity existing near the surface of the photoconductor, and an attracting force is generated between the charge of the toner and the charge of the opposite polarity near the surface of the photoconductor, preventing the toner from scattering.
