Title: Failure detection pair cable
Inventor: SHIMADA MASAHARU
IPC: G01R31/02
Filed: 1979-06-20
Abstract: PURPOSE: To detect failure while making it unnecessary for those engaging in maintenance to vist a far side by a method wherein a voltage applying means and a means for interrupting the connection between cables are provided at a near side and a far side respectively, and furthermore a pulse signal detecting means at the near side and a DC current interrupting means at the far side are provided.  
     CONSTITUTION: In connection with the pair cables of the communication system through which communication is possible without the supply of DC current, if an exciting winding 6 is excited by applying a DC power source 3 at a near side, a contact point 6a repeats on and off, generating a DC pulse signal in a cable 1. A condenser 8 interrupts the circuit in form of DC in such a way that DC current does not flow to equipment illustrated in a rough sketch on the far side beyond the far side, so that the damage of the equipment is prevented when the DC current is being sent. Although the pulse signal is detected by a detector 7 via a resistor R, it can be judged that there is no failure in the pair cables. Otherwise, if there exists short- circuiting 5, the occurrence of a failure can be informed because the detector 7 is not capable of detecting the pulse signal.

Filed: 1985-04-11
Abstract: PURPOSE:To enable conveying of paper sheets in a sure manner, avoiding contact of transferred surfaces of the sheets with other components of the equipment by conveying the sheets that are being held by a belt at the edges and being hung therefrom. CONSTITUTION:The toner image formed on a peripheral surface of a photosensitive drum 1 is transferred by a transfer charger 9 onto the bottom surface of a paper sheet 8 which is sent from a cassette 22 through rollers 6 and 7. The paper sheets 8 after transferring are adjusted to be straight by a guide bar 10. On the other hand, when a belt 11 which is being moved by pulleys 12 and 14 turns around the pulley 12, slits on the belt gradually open corresponding to differences in the straight moving directions at the curve and changes in angles at the pulley 12. Measuring timing between the paper feeding speed and the driving speed of the belt 11 at the transfer charger 9, a paper sheet is pushed forward to the slit 11a when it is open, and the edge of the sheet is caught by the slit 11a. As the belt 11 changes its shape from flex to straight, following the rotation of the pulley 12, the slit 11a closes, and the paper sheet 8, which is being hung, is conveyed to a fixing device 13.

Title: Injection molding method of hollow panel and injection mold therefor
IPC: B29C45/63
Filed: 1992-03-31
Abstract: PURPOSE:To obtain a hollow panel having reinforcing ribs therein by advancing a slide core fitted in one mold and equipped with projections into the cavity. forming a small narrow part between the projections and another mold for injecting resin, and withdrawing the slide core while supplying high pressure gas. CONSTITUTION:The stationary mold 2 has a slide core 7 fitted therein which is impulsively movable toward a cavity C defined by itself and a movable mold 3. The slide core 7 is provided with a plurality of projections at a predetermined distance and when situated in the withdrawal position, the smooth surface 7a between projections is caused to be in flush with the cavity surface of a mold main body 6. At an advancing position, it runs into the cavity C for defining a small narrow part between the upper surface of the projections and the smooth surface 3a of the movable mold 3. At the advancing position, when molten resin is infected and high pressure gas is supplied, a hollow part is formed. As the supply of high pressure gas is supplied and the slide core 7 is withdrawn, the volume of the hollow part increases and, as a result, the wall thickness of molten resin in the small narrow part comes to be thin and thus be reinforcing ribs.

Filed: 1996-03-29
Abstract: PROBLEM TO BE SOLVED: To prevent futile exchange of developer and to maintain the characteristic of the developer over a long period by exchanging the developer, according to a detection value for detecting the degree of a deterioration in the developer. SOLUTION: When a measured value C reaches an operating time C0 as a set fixed value for the developer, the degree of the deterioration is measured. When the degree of the deterioration in the developer is measured, a measured value A is compared with a set value A0 previously set, so that when it is judged that the deverloper is deteriorated, an exchanged developer quantity (a recovered developer quantity and a supplied developer quantity) is decided from the results of the comparison of the measured value A with the set value 40 previously set.  The exchange operation of the developer controlled according to the decision is as follows: a shutter 43 arranged in the lower part of a developing unit is opened, to control an opening time, for recovering the developer in the developing unit into a recovering container 32 by the decided recovered quantity and is closed after the recovery is completed and a developer supplying roller 38 starts to rotate, so that the operation of controlling the rotational time of a roller is executed so as to supply a virgin developer by the same supplied quantity as the recovered quantity and when the supply of the developer is completed, the exchange operation of the developer is completed.

Abstract: PURPOSE:To suppress air bubbles between adhesive boards at the time of adherence of ultrahigh density and high multilayer printed board by providing a plurality of bank members surrounding the outer peripheries of a plurality of hot plates, and detachably providing a plurality of packing members for sealing between the plurality of bank members. CONSTITUTION:A printed circuit board 27 of a material to be adhered, grasped by upper and lower jig plates 26a and 26b, is inserted between a lower hot plate and an upper hot plate.

Since the banks 8 surrounding the plates T are heat-insulated by a sheet packing 7, the packing 9 is not possibly thermally deteriorated. Since a vacuum adhesive chamber of small volume surrounding the plates T is composed of the banks 8, a material to be adhered adheres in a state of arriving at high vacuum at a high speed.
