Title: Phase servo circuit of reproducing device
Inventor: TANAKA MASATO
IPC: G11B15/46
Filed: 1984-07-31
Abstract: PURPOSE:To discriminate a sure recording mode independently of unarranged track patterns by controlling the motor phase of a recording medium in response to a resulting value adding a prescribed value to a difference based on a write/ read address. CONSTITUTION:A write address WA and a read address RA are fed to an operation circuit 20, where a difference is obtained and this difference is a value in response to an error of a motor 2. Further, a prescribed offset is given to the circuit 20 and this value is selected to a value in response to a phase difference (alpha=180 deg.) between addresses WA and RA where the WA does not surpass the RA or vice versa even if the WA is changed. A value adding the difference between the addresses WA and RA to the offset is converted (21) into an analog error signal, which is fed to a servo amplifier 13 to apply phase control to the motor 2. Since the center point WA of the speed change range is controlled while keeping an interval of 180 deg., overflow/underflow of a RAM 8 is caused.

Title: Support body for pressure sensitive recording paper
Inventor: KIMURA SHIGEAKI
IPC: B41M5/30
Filed: 1990-06-19
Abstract: PURPOSE:To reduce winding curls which occur at finishing an extra small roll by specifying water absorbing property and smoothness at the top surface (surface to which a pressure sensitive liquid is to be coated) and the back surface (surface to which the pressure sensitive liquid is not to be coated) of a stencil paper. CONSTITUTION:A support body for a pressure sensitive recording paper is made by using a head box having a slit with 1mm width. A water transition quantity at both surfaces of the support body is 15ml/m<2> or less and a smoothness at both surfaces of the support body is l00sec. or more when the both surfaces of the support body are measured by a feed speed of 0.5mm/sec. winding curl of a pressure sensitive recording paper occurs due to a potent influence of an internal stress remaining as an internal distortion in the support body when it is shaped in an extra small roll. The internal stress occurs due to an expansion of the support body caused by a liquid such as a pressure sensitive coating liquid during a process of the pressure sensitive recording paper and due to a dry immediately after the process under a tension of the support body. Therefore, a lesser liquid permeation is preferable and this property is expressed by a Blistol test. A higher smoothness makes the curl smaller effectively with the Blistol test property.

Title: Timer device for camera power source
Inventor: HASEGAWA HIROSHI
IPC: H03K17/28
Filed: 1978-12-28
Abstract: PURPOSE: To surely cut off power source sccording to timer counters for power source by stabilizing the operations of switching transistors by way of a capacitor.  
     CONSTITUTION: When a switch S closes in cooperation with shutter button, the transistor Tr 5  conducts and electric power is supplied to the load of exposure calculation from a primary line 10 via secondary line 20. When the switch S is opened, the transistor Tr 1  conducts and the resetting of the flip-flops FF 1 ... of the timer counter for power source is released, whereby timer counting is accomplished. Upon completion of this counting, the output of the timer counter inverts, then the transistor Tr 2  goes OFF, the transistor Tr 3  goes ON and the transistors Tr 4 , Tr 5  go OFF, thereby cutting off the power source of the secondary line 20. Here, together with the OFF of the transistor Tr 5  the increase in the ON resistance of the transistor Tr 3  with a decrease in the output voltage is prevented by the charging charge of a capacitor C, thus the power source is surely cut off after the lapse of the specified time corresponding to the timer counter without any malfunction owing to unstable transient phenomena.

Inventor: HIROSHIMA KOICHI
IPC: G03G15/00
Filed: 1988-06-29
Abstract: PURPOSE:To impart high transfer efficiency and durability to the title device by using a specific, inherent volume resistance body for the central part of a transfer carrying belt which carries a transfer material to an image carrier and transfers an image by an electric field, and strengthening the tensile strength in both edges of the belt more than in the central part. CONSTITUTION:A toner image corresponding to image information is formed on the surface of the drum 31. With the aid of the electric field of a roller electrode 32, the image is transferred in an image transfer part (a) onto the transfer material P carried by the transfer carrying belt B. Accordingly, 10<8>-10<15>OMEGAcm is the suitable range of inherent volume resistivity for the central part 1 of the belt B on which the transfer material P is placed, to prevent electrostatic adsorption and charge-up in development. At present, semiconductive material of this range lacks strength as a belt, so that both edge parts 2 are coated with, PET, etc., and strengthened. Thus, freedom is increased in selecting the belt material, and the belt B including the central part in high transfer efficiency and both edge parts excellent in abrasion resistance is formed.

Title: Continuous production of polycarbonate granules
Inventor: SHINOMIYA HIROTADA
IPC: C08J9/28
Filed: 1982-09-20
Abstract: PURPOSE:To produce uniform granules having a high density, by a method wherein a solvent of a solution of a polycarbonate is evaporated while exerting a shearing force on the solution by passing the solution through a gap so provided as to generate a shearing force. CONSTITUTION:A polycarbonate is dissolved in a solvent such as methylene chloride or chloroform to produce a solution. A shearing force is exerted on the solution by the gap 4 formed by a fixed disk 2 and a rotatable disk 3. When the solution is supplied through a supplying port 1 while rotating the disk 3 through a driving shaft 5, the solution is subjected to a shearing force and a centrifugal action by the velocity difference between the fixed disk 2 and the rotatable disk 3. Accordingly, upon receiving the strong shearing force, the solution is concentrated while being moved, and is gradually converted into granules in a collapsing manner, starting from the end of a string form material. The granules are repeatedly subjected to a granulating action until being discharged, so that they are made to be uniform granules.
