Title: Image forming device
Inventor: TAKEDA ATSUSHI
IPC: G03G15/00
Filed: 1998-07-01
Abstract: PROBLEM TO BE SOLVED: To prevent a faulty image from being formed caused by defective electrification occurring in accordance with the soil of a contact type electrifying member being over an allowable range and to prevent a serious problem from occurring caused by the attachment of carrier by detecting difference between the electrifying potential of a body to be electrified and voltage applied to the electrifying member and forming an image other than image information at an image part according to the detection signal thereof. SOLUTION: The electrifying member 2 to which the voltage is applied is brought into contact with the body to be electrified 1 so as to electrify the body 1. Then, the difference between the electrifying potential of the body 1 and the voltage applied to the electrifying member 2 is detected. According to the detection signal, the image other than the image information is formed at at least the image part. That means, the image other than the image information is intentionally formed by changing the condition of bias applied to the contact type electrifying member 2 so that the potential of the body 1 becomes a desired value in accordance with the deterioration of the electrifying member 2 and regarding that the deterioration of the electrifying member 2 becomes over the allowable range when the value which should be changed is over some value.  Thus, the faulty image is formed so as to press maintenance.

Title: Tracking servo circuit
Inventor: TERADA AKIO
IPC: G11B21/10
Filed: 1984-09-26
Abstract: PURPOSE:To perform invariably the best tracking servocontrol by controlling the gain of a variable gain circuit according to a tracking error signal when a light beam makes a scan across plural groove or pit arrays, and maintaining the control gain. CONSTITUTION:The difference output of reflected or transmitted light obtained by projecting the light beam upon a recording medium where pregroove or pit arrays are formed is passed through the variable gain circuit to obtain the tracking error signal. The input and output terminals of the variable gain circuit are connected to one input terminal and output terminal of an analog multiplier 20 respectively, and the output of the multiplier 20 is supplied to a holding circuit 24 through an envelope detecting circuit 21, differential amplifier circuit 22, and voltage comparing circuit 23. The gain of the multiplier 20 is controlled with the output of the circuit 24. The switch SW1 of the circuit 24 is turned on during a crossing scan on groove or pit arrays formed on the recording medium, and turned off when tracking servocontrol is on. Thus, the gain of the tracking servo circuit is controlled to perform invariably the best servocontrol.

Title: Magneto-resistive magnetic head
Inventor: WATANABE TOSHINORI
IPC: G11B5/39
Filed: 1994-08-03
Abstract: PURPOSE:To minimize kinds of magnetic materials to be used and to obtain a sufficient magneto-resistive element with a magneto-resistive magnetic head of a SAL bias system. CONSTITUTION:The MR layer 1 and SAL layer of the magneto-resistive magnetic head having a laminate composed of the MR layer 1 exhibiting a magneto- resistive effect, a SHUNT layer 2 constituting a nonmagnetic layer and the SAL layer 3 for applying a transverese bias magnetic field to the MR layer 1 are formed of the same magnetic films consisting of Ni81Fe19. Since the SAL layer 3 is magnetically satd. in the same direction as the direction (y direction) of the leak magnetic fluxes of a recording medium, the magnetic permeability in the (y) direction of the SAL layer 3 lowers and the MR effeting function in the SAL layer 3 is suppressed. Although the MR layer 1 and the SAL layer 3 are formed of materials having the same specific resistance rho, detecting currents are sufficiently passed to the MR layer 1 by forming the MR layer 1 to the film thickness larger than the film thickness of the SAL layer 3. The magnetic detection output of high accuracy is thus obtd.

IPC: B65F3/20
Filed: 1988-08-11
Abstract: PURPOSE:To let a packing plate be separated and evacuated from hard refuse automatically by providing an actuation commanding means which allows the packing plate to go back to an initial starting point while temporary lifting and temporary normal rotating are alternately repeated on the part of the packing plate after operating hydraulic pressure has been rapidly increased upon pressing on hard refuse of the packing plate. CONSTITUTION:When a packing plate 11 comes in contact with hard refuse during a primary pressing stroke, operating hydraulic pressure is rapidly increased in the hydraulic pressure circuit of a cylinder 14 so that an increase in pressure is detected. In this case, the sliding cylinder 14 is actuated by a command signal stored in an operation command means, the packing plate 11 is temporarily lifted so as to be separated and evacuated from refuse so that an increase in hydraulic pressure is instantly released. Then, the packing plate 11 is normally rotated temporarily by a packing cylinder 13. The alternate repetition of these temporary lifting and temporary normal rotation allows the packing plate 11 to go back to an initial starting point W so as to let the next cycle start operating.

Title: Memory controller for tree-dimensional pattern
Inventor: USHIWAKA KEIICHI
IPC: G06T11/60
Filed: 1987-08-13
Abstract: PURPOSE:To write data at a high speed by comparing introduced depth information with that stored in a depth information storing means in parallel by an extent equal to plural image elements. CONSTITUTION:Color information and depth information on each image element of a three-dimensional pattern are stored in a color information storing means 111 and a depth information storing means 121 respectively. When both color and depth information corresponding to plural image elements are introduced, a comparison means 131 compares those depth information with the depth information stored in the means 121 in parallel. Then the color information on the revalent image element is outputted to the means 111 in response to the depth relation of the relevant image element. In such a way, both of depth information are compared with each other by an extent equal to plural image elements. Thus the data on the three-dimensional pattern can be written at a high speed.

Title: Transmitter receiver for coherent optical communication
Inventor: CHIKAMA TERUMI
IPC: H04B10/564
Filed: 1986-08-28
Abstract: PURPOSE:To obtain a transmitter receiver for coherent optical communication with inexpensive and high reliability by switching or branching a light of a light source whose frequency is stabilized into transmission and reception use by an optical switch/branch circuit so as to use one light source for a transmission light source and a local oscillation light source for reception. CONSTITUTION:One light source is used for location oscillation at 'Listen' and for transmission at 'Talk' so as to constitute a transmission/ reception equipment inexpensively. Since one light source 11 is used for transmission and local oscillation by an optical switch/branch circuit 12, two sets of frequency setting/stabilizing circuits 10 or the like for the purpose are not required. Thus, the number of circuit components is reduced remarkably than a conventional number.

Title: Forging forming method of gear component having oil groove
Inventor: OKAMOTO ICHIRO
IPC: B21J5/02
Filed: 1984-09-27
Abstract: PURPOSE:To improve a productivity by forming the core burr caused on a shaft hole part with discriminating by making a step from an oil groove part, then by punching the core burr. CONSTITUTION:A lower die punch 16 being fitted to the knockout pin 17 taking out a work 1 is provided. A core burr 11 is formed with a step being made in the space with an oil groove part 10, due to the tip part of the lower die punch 16 projecting toward an inner punch 2. With said method the core burr is formed with only driving the lower die punch 16 onto the work 1, also the punching force for burr punching has no effect on the oil groove part 10 in case of forging. The oil groove part 10 does not need to receive the punch force therefore and the oil groove die is made disused. Furthermore the man- hour in the position setting work of the work 1 and punching die is eliminated and the productivity is improved together with the reduction in the work man- hour of a die.
