Abstract: PURPOSE:To eliminate the abutting irregularity of a contact type electrical conductive member on the back surface of a transfer material carrying member and to prevent the disorder of an image such as the stripelike irregularities of gradation of the image, the pattern omission of the electric discharge, the color slippage or the splashing of the image from occurring by generating a transfer electric field by using the contact type electrical conductive member such as an electrical conductive brush as a transfer electric field forming means. CONSTITUTION:The transfer electric field forming means 40 is constituted of the electrical conductive brush 21 which abuts on the back surface of a dielectric sheet 93 in an image transfer area, a bias power source 30 which is connected to the brush 21 and which impresses a voltage for generating a transfer electric field or the like. The brush 21 is arranged so that the sheet 93 is pressed and brought into contact with a photosensitive drum 3 by the brush 21 having elasticity at a position where a transfer material which is extended toward the downstream side of the moving direction of the sheet 93 from the introducing side and carried by the sheet 93 is finished being brought into contact with the drum 3. Then, an expression is satisfied between the resistance (alphaB) of the brush 21 and contact resistance = (alphaC) between the brush 21 and the sheet 93. Wherein, a symbol A shows the constant of 1 or more in the expression.

Title: Recording/reproducing device for optical recording medium
Inventor: OHATA HAJIME
IPC: G11B7/004
Filed: 1989-03-31
Abstract: PURPOSE:To prevent the wrong recording of information by using a switch to grant or inhibit the recording of information to an optical recording medium and therefore preventing the recording of information to a specific optical recording medium even if a recording command is received from a host device. CONSTITUTION:When a switch SW is set in a recording enable state, a recording/reproducing device 20 records the information on an optical recording card 30 based on the recording command received from a host computer 10. On the other hand, the device 20 is inhibited from recording the information on the card 30 even if a recording command is received from the computer 10 as long as the SW is set in a recording unable state. Thus it is possible to inhibit the recording of information on the card 30 even if a recording command is received from a host device, therefore, to prevent the wrong recording of information.

Abstract: PURPOSE:To detect a stable magnetic bubble signal by giving a value decided based on a value obtained by means of sample-holding the output of a differential amplifier to a comparator which is used for the differential amplifier and to which the output of the differential amplifier is given as a threshold. CONSTITUTION:When the driving of a rotary magnetic field is started at time T0, the generation start signal of the rotary magnetic field is inputted to a delay circuit 51.

A DC constant voltage VT generated in a constant voltage DC power source 53 is added to the reference voltage level by a voltage addition circuit 54 and it is given to one terminal in a comparison circuit 4 as a reference level. Then, the reference level is compared with the output (a) of the DC differential amplifier 3, which is given to the other terminal of the comparison circuit 4, and the magnetic bubble signal (b) is outputted from the comparison circuit 4. Thus, the stable magnetic bubble signal can be obtained.

Title: Circuit device
Inventor: TAKAYA MANABU
IPC: H05B41/18
Filed: 1990-03-30
Abstract: PURPOSE:To prevent parts of a circuit device from being damaged by thermal shock by causing a holder to which a temperature detecting element is mounted to automatically adjust the positions of the temperature detecting element and parts of a heating circuit relative to each other according to the service conditions of the temperature detecting element. CONSTITUTION:A holder 40 supporting a temperature fuse 30 is formed by a thermally reactive member 40 such as a bimetal or shape-memory alloy and the end of the member 40 is fixed e.g. to a lamp support plate 5. To light a lamp under the condition of low ambient temperature, the member 40 is deformed in such a manner as bringing the temperature fuse 30 close to a bulb wall, and when the ambient temperature is high the member 40 is deformed in such a manner as separating the temperature fuse 30 from the bulb wall. During normal lighting, initial temperature conditions can therefore be equalized even with the temperature gradient of the bulb wall, and when an abnormal temperature rise occurs as in semi-wave discharge the operating temperature of the temperature fuse 30 is reached under similar conditions and so nonconformities due to the temperature gradient of the bulb are prevented.

Title: Lens information introducting device in camera
Inventor: SHIMOMURA JIYUN
IPC: G03B7/00
Filed: 1978-07-12
Abstract: PURPOSE: To enhance reliability with a simple and inexpensive constitution by coupling a lens and camera body optically.  
     CONSTITUTION: Code patterns 4 for the purpose of quantizing aperture value information is provided in parallel with an aperture pattern 3 on the outside surface of an aperture ring. The patterns consist of the fringes which are binary-coded to bright and dark. In the configuration of the fringes, one set of the fringes corresponds to one aperture value, thereby forming an optical code plate. On the other hand, one set of the fringes is contained on the camera body 1 side and the optical system for imaging and projecting the conjugate image thereof on the photo detecting faces of the photo detectors 5 fixed on the camera side is beforehand formed by an imaging lens 7 and a reflecting mirror 6 which directs the light from the patterns 4 to the lens 7. The photo detecting faces of the elements 5 are divided to five segments and the respective segments generate 5 sets of photoelectric output signals independently in correspondence to the brightness and darkness of the projected fringes and therefore the digital signals corresponding to the bright and dark fringes may be obtained. Thereby the reliability of the device may be enhanced by the simple and inexpensive constitution.

IPC: H05K3/46
Filed: 1988-04-05
Abstract: PURPOSE:To obtain multilayered wirings of aluminum electrodes and transparent electrodes having low resistance and excellent pattern forming and contact characteristics by forming a thin silicon layer between the electrode consisting of an aluminum metal and the transparent electrode layer provided thereon. CONSTITUTION:The thin silicon layer 3 is formed between the aluminum electrode 2 provided on a glass substrate 1 and the transparent electrode 4 layer provided thereon. The thin silicon layer 3 is thinly formed on the film of the aluminum 2 formed in such a manner, then the silicon, has the high resistance to hydrochloric acid, phosphoric acid, etc. and etching soln. for ITO (indium tin oxide) and aluminum and, therefore, the selective etching with the ITO 4 is possible. The silicon and the aluminum generate an eutectic point to effect reaction and silicification 5, thus lowering the resistance in the subsequent annealing. The contact resistance between the aluminum 2 and the ITO 4 is thereby decreased and the wiring of the aluminum electrode 2 and the ITO electrode 4 having the excellent patterning characteristic is enabled with the good contact.

Title: Frequency controller for compressor
Inventor: UNITA HIROYUKI
IPC: F24F11/02
Filed: 1984-04-25
Abstract: PURPOSE:To prevent a compressor from locking or vibrating at a low frequency due to oil lack by accelerating the frequency rising speed when the compressor is started. CONSTITUTION:The frequency of a compressor is rapidly raised up to a time t0 when the compressor arrives at the prescribed frequency f0 as shown in a characteristic curve (b), and when exceeding the prescribed frequency f0, it is smoothly raised or lowered. Thus, since the variation amount of the rotating speed is heretofore small at the compressor starting time, lubricating oil is not sufficiently circulated into the compressor to cause the compressor to be locked or vibrated at a low frequency. But this controller can prevent it and provides various advantages such as quick cooling or heating effect and elimination of noise at frequency altering time in an air conditioner.
