Title: Electrophotographic device
Inventor: KATSURAGI SHIGERU
IPC: G03G15/20
Filed: 1995-03-23
Abstract: PURPOSE: To provide an electrophotographic device simple in structure, small in size and capable of preventing an overheat on the end part of a fixing roller even in the case of fixing a recording paper of the narrower width than the fixation width. CONSTITUTION: A heat radiation roller 11 is pressed to and away from the fixing roller 7 through heat radiation roller control means by system control means not shown in Figure. When a recording paper width detection means detects the recording paper of the narrower width than the fixation width, the heat radiation roller 11 is pressed onto the fixing roller 7, the heat of the overheat part on the end part is radiated to the recording paper passing part where the temp. is dropped to uniformly keep thermal distribution of the fixing roller 7. Timing when the heat radiation roller control means drives the heat radiation roller 11 is decided based on the timing when the passing of the recording paper is detected by a recording paper passing detection means provided on the front of the fixing roller.

Title: Heat exchanger
Inventor: ISHIYAMA MASAAKI
IPC: F28F1/32
Filed: 1989-03-17
Abstract: PURPOSE:To prevent stress from concentrating in repeated heating and cooling by filling a gap between a collar part of a heat absorption fin and an adjacent heat absorption fin with a brazing material or the like and making uniform the thickness of a pipe. CONSTITUTION:A heat exchanger 1 comprises many heat absorption fins 5 and heat exchanging pipes 4 penetrating the formers, and there is filled a gap between a collar portion 5a of the heat absorption fin 5 and the heat absorption fin 5' with a brazing material 6 or the like. Combustion gas produced by a burner 3 passes through a combustion chamber 2 and through the gap between the respective heat absorption fins 5, 5' of the heat exchanger 1. Water receives heat from the heat absorption fins 5, 5' and from the heat exchanging pipe 4 and changes to hot water. Although there is produced thermal stress owing to repeated cooling and heating on the heat exchanging pipe 4 upon the burner 3 being on and off, no stress is concentrated on the gap between the collar part 5a of the heat absorption fin 5 and the heat absorption fin 5' because of that gap filled with the brazing material 6 resulting no less thickness portion.

Title: Fault search system of digital transmission system
Inventor: SEKI NORIO
IPC: H04B17/40
Filed: 1979-05-25
Abstract: PURPOSE:To make a seach for a fault by providing a repeater with the function of starting a PN(artificial random signal) sequence generating circuit when a signal from a prior-stage repeater is interrupted and the function of stopping a specific repeater from relay operating on detecting a control signal of specific repetitive cycles from a supervisory station. CONSTITUTION:When signals can not be sent out due to a fault of repeater R1k at the prior stage of repeater R1k+1 and optical fiber l between repeater R1k+1 and prior-stage repeater R1k is cut off, each repeater detects no received signal arriving to actuate PN sequence generating circuit 1 which generates a PN sequence of cycles characteristic to each trunk line. Then, PN sequence P is sent to the post-stage supervisory station M, which detects cycles of this PN sequence to judge repeater R1k+1 corresponding to the cycles, thereby identifying as a fault position an optical fiber extending to prior-stage repeater R1k or prior-stage repeater R1k.

IPC: G11B7/135
Filed: 1999-03-11
Abstract: PROBLEM TO BE SOLVED: To make constant a position of incidence of a luminous flux to an objective lens by moving a deflecting mirror in accordance with a rotational angle of a galvano mirror and a position of a carriage and bringing the luminous flux from the galvano mirror to the same position of the objective lens irrespective of the rotational angle of the galvano mirror. SOLUTION: When a galvano mirror 26 rotates by an angle θ in the counterclockwise direction, an angle of projection of a laser luminous flux from the galvano mirror 26 changes by 26. When the laser luminous flux advances an optical path length L to reach an objective lens 10a, a center of an intensity distribution of the laser luminous flux shifts upward by Ltan2θ to an optical axis of the objective lens 10a. Based on the rotational angle 6 of the galvano mirror detected by an angle detection sensor and a position L of a first carriage detected by a positioning sensor, a movable prism 50 is moved upward by H= Ltan2θ. Accordingly, a center of the laser luminous flux enters a center of the objective lens 10a.

Abstract: PURPOSE:To reduce resistance on a tap and enable the prevention of the fracture of even a small-sized tap by providing a control means for a digital spindle motor in the tapping control of a machine tool using said motor. CONSTITUTION:Speed instructions 'VS' and 'VZ' depending upon a specified pitch amount are inputted to a position control means 4 and the position control part 12a of a servo circuit 12 from an interpolation circuit 3a as distribution pulses 'PS' and 'PZ'. Also, the position control means 4 makes speed control for a spindle motor 1 on a difference from the feedback pulse 'FS' of a pulse coder 'PC1' via a digital circuit 5 and a power circuit 6. The servo circuit 12 similarly makes synchronous control for a servo motor 2 on the basis of a feedback pulse 'FZ'. When a tap has shifted by a pulse distribution amount (d1) in the aforesaid constitution, both motors 1 and 2 synchronize and the rotation thereof is reversed, according to a reverse rotation instruction. When the tap has returned by (d2), said motors 1 and 2 are caused to give normal rotation again, thereby shifting the tap by d1+d2. Thereafter, a similar fixed cycle is repeated and machining is made up to a predetermined depth.
