Filed: 1994-10-17
Abstract: PURPOSE: To accurately secure an optimum blade gap by providing an attaching means capable of varying a relative positions of the shaft center of the bearing part of a bearing member and a developing device main body. CONSTITUTION: A part for supporting the bearing member 24 and a blade 25 are integrally formed as a supporting member 27 constituting the part of the developing device main body 21. Furthermore, the member 24 is attached to the member 27 through an attaching member constituted so that a specified axle-to-axle distance is secured between the center shaft of the bearing part and the center shaft of an external peripheral surface. The attaching member has a mechanism for plurally or freely changing an attaching angle with respect to the member 27. The attaching member can adjust the shaft center position of the member 24 pivotally bearing a developing roll 23 in the up and down directions by changing the attaching angle with respect to the member 27. As a result, the blade gap can be changed by moving the roll 23 up and down with respect to the main body 21.

Title: Micromachined velocity sensor system for sensing rotating speed and method for minimizing parasitic driving voltage
Inventor: HIYUU JIEI MAAFUII
IPC: G01C19/5719
Filed: 1995-09-28
Abstract: PROBLEM TO BE SOLVED: To provide a device and a method for minimizing parasitic driving voltage penetration in a speed sensing system. SOLUTION: A micro-machined speed sensor system includes plural tested masses 310, 312 or plates connected to plural electrostatic combs 340, 342, 344, 346. A comb drive amplifier 322 induces the deflection of the sensing plate. Motor combs 340, 342 are driven by half NRF(natural resonance frequency) by connecting the comb drive amplifier 322 to a half-frequency motor oscilator 400. The half-frequency motor oscillator 400 provides the driving voltage with the half NRF(natural resonance frequency). Accordingly, undesired parasitic drive penetration is removed by the motor frequency to heighten the efficiency.

Title: Roll bender device for rolling mill
Inventor: SUZUKI MAKOTO
IPC: B21B13/14
Filed: 1983-12-29
Abstract: PURPOSE:To enable a work roll to perform bending and to reduce edge drop by applying a force of axial direction to the axial end of work roll and applying a bending force to the work roll by the component of said force.

Title: Head loading device of electronic still single-lens reflex camera
Inventor: MORISAWA TAHEI
IPC: H04N5/765
Filed: 1983-12-24
Abstract: PURPOSE:To perform the head loading action without using a special drive source such as a straight-drive solenoid, etc. by using a coupling mechanism which interlocks a video mirror driver to obtain a press contact between a recording medium and a magnetic head. CONSTITUTION:When a shutter button is pushed, a mirror driver 23 is actuated to conduct an energizing magnet 50 and to attract an armature 49. As a result, the engaged state is released between a hook lever 46 and an action arm 41 of an action lever 46. The arm 41 is turned by the force of a tension spring 45 to push up an action pin 39. Thus a video mirror 13 is moved up until it becomes horizontal to the optical axis. Therefore a coupling arm 44 hits a coupling projection 61 of a coupling lever 60 and a load bar 63 is pulled forward with the back of a pressure pad pushed forward. This pressing power presses a magnetic disk toward a magnetic head. Thus the proper contact pressure (recording pressure) is produced between the magnetic head and the magnetic disk.

Title: Evaporation cooling type electric equipment
Inventor: MIZUGUCHI NOBUHIRO
IPC: F25D9/00
Filed: 1989-09-27
Abstract: PURPOSE:To obtain a evaporation cooling type electrical equipment capable of reduction of the lowering of a fluid level in a container upon excess load by providing return tubes communicating with the bottoms of the opposite ends of a coupling tube and the lower part of the fluid level of a cooling medium fluid in the container. CONSTITUTION:In case of an electrical railway rectifier, returned fluid receivers 31 are provided at bottoms of coupling tubes 3 on opposite sides of the same where an evaporator 2 holds therebetween a location of the coupling tube 3 opening to the central bottom part, and return tubes 21 connect the bottoms and the lower position of cooling medium fluid 5 lower than the fluid level in a container 1. The cooling medium cooled and liquefied in a condenser 4 once falls into the return fluid receiver 31 and moves along the bottom and further enters the return tube 21 as return fluid 52. Thereupon, since the bottom position of the return fluid receiver 31 is deeper than that of the coupling tube 3, the entering cooling medium fluid does not return to the container 1 from the evaporator 2. Further, since an opening part of the return tube 21 toward the container 1 is located below the fluid level of the cooling medium fluid 5, any vapor stream by boiling does not enter the container, and the return fluid can smoothly enter the return tube, the amount of the fluid staying in the coupling tube is very small. Thus, there can be reduced the lowering of the fluid level of the cooling medium fluid in the container upon excess load.

Filed: 1988-10-07
Abstract: PURPOSE:To prevent the occurrence of a pseudo color in a reproduced picture by adding color difference signals and signals obtained by delaying the color difference signal for 1H and averaging the above-mentioned signals. CONSTITUTION:The color difference signal demodulated by an FM demodulating circuit 12 is inputted to a 1H delay circuit 13 and delayed for 1H, and color difference signals R-Y and B-Y, which are made into a simultaneous state, are obtained by giving this 1H delay signal and the color difference signal, which is not delayed, to a simultaneous circuit 14 and alternately switching the two signals. Further, the R-Y signal and its 1H delay signal are added by an adder circuit 16, the two signals are averaged by multiplying the added result by 1/2, and in an adder circuit 26, the B-Y signal is averaged in the same manner. These averaged color difference signals are inputted to a matrix circuit 20. Thus, it can be reduced or prevented that the pseudo color such as a line crawl occurs in video to be reproduced on a display device based on respective signals to be outputted from R, G, and B terminals.

Title: Mouse input device
Inventor: SHIMOZATO HIDETO
IPC: G06F3/0354
Filed: 1989-09-28
Abstract: PURPOSE:To improve portability without degrading operability by switching a size on the external thickness of a mouse input device to a first thickness fitted to an operation and to a second thickness for storage. CONSTITUTION:When a lock pin 109 is removed and an upper case 101 is pushed down against the force of a spring 106, a movable cover 102 slides the sliding surface of a lower case 104, collapses to the inner side of the case and stops at a a place, where a movable shaft 107 is brought into contact with the lower case. Thus, the device comes to a state at the time of storage if the lock pin is inserted again. For switching the stat at the time of storage to that for the operation, the upper case 101 is lifted upward by the operation of the spring 106 with the lock pin removed, and it stops at a place where the movable cover is caught by a claw. Consequently, the thickness at the time of storage is reduced to nearly half of the thickness at the time of operation. Thus, the portability of the device can be improved.

Title: Detection device for head position
Inventor: SAKAE KOJI
IPC: G11B7/085
Filed: 1989-09-28
Abstract: PURPOSE:To reduce the effect due to a disturbance light and to correctly detect the position of a head by demodulating the output of a light receiving means into a modulation signal and constraining the noise component of a demodulation output by a low pass filter. CONSTITUTION:A parallel light emitted from a light source 11 is made incident on a cylindrical lens 12, converted into a diffused light, made incident on a light receiving element 13 and various disturbance lights excepting the light emitted from the cylindrical lens 12 are made incident on the light receiving element 13. However the output of a demodulator 23 is input to a low pass filter 24, which not only smooths the signal input from the demodulator 23 but also restrains the noise component included therein. A detector 25 detects the position(distance between the cylindrical lens 12 and light receiving element 13) of a carriage 14 from the signal input from the low pass filter 24. Thus the effect due to the disturbance light, etc., is reduced and the head position can correctly be detected.
