Title: Doppler velocity measuring device
Inventor: MATSUMARU KENJI
IPC: G01S17/58
Filed: 1978-10-11
Abstract: PURPOSE:To increase the S/N ratio as well as to increase the velocity measurement range for the object to be measured by giving the two analogous division to the dispersion light sent from the measured object and then receiving the divided light at each photoelectric converter to obtain the difference of the electric output between these photoelectric converters. CONSTITUTION:The light sent from laser light source 1 is divided into two parallel luminous fluxes via beam splitter 2 and reflecting mirror 3 and then receives the cross interference on measured object 8 through condenser lens 4. The dispersion light sent from object 8 is divided into two analogous parts by half-mirror 5 and via lens 4 and then received at photoelectric converters 6 and 7 each to obtain signals S1 and S2. These signals receive adjustment at sensitivity correction circuits 10 and 11 to secure the identical mean value to each other and then pass through differential amplifier 12 for elimination of the DC component, the low frequency component, the laser noise and others. As a result, the S/N ratio is increased to obtain only the Doppler component, thus increasing the velocity measurement range for object 8.

Title: Sheet conveyor for electrophotographic printer
Inventor: SUZUKI TAKASHI
IPC: G03G15/00
Filed: 1988-05-20
Abstract: PURPOSE:To keep off any printing failure due to speed variations in a sheet conveying part being caused immediately after print starting by installing a rotary brake shaft in a buffer turning shaft, and making a buffer lighter in weight. CONSTITUTION:A rotary braking device 14 consists of a brake ring 15, a on-way clutch 16 and a screw 17, and two clutches 16 are inserted into this ring 15 so as to differ in a direction of rotation. Therefore only one side of the one-way clutches is rotated by the rotational direction of a shaft 12. Utilizing rotation in this one-side only if the clutches 16 are clamped by screws 17-a, 17-b from top of the ring 15, separate brake forces are giveable to turning effort in both directions by a difference of clamping force between both screws 17-a and 17-b, and this brake force absorbs impact energy. Moreover, with one sheet of buffers removed, sharp lightweightiness in a printer is well promoted. Thus, character blurredness is almost prevented from occurring.

Title: Display system for tape position
Inventor: UNNO HIROAKI
IPC: G11B27/34
Filed: 1981-08-10
Abstract: PURPOSE:To prevent the unnatural display of used amount of a tape, by correcting the display by utilizing the fact that the used amount of tape at one reel revolution should be limited within a prescribed range. CONSTITUTION:Rotating periods t1 and t2 of winding and supply reels are detected via photodetectors 21 and 22 at the constant run of a VTR tape at recording and reproduction, and time T2 of used tape is calculated based on a formulaIwith a microcomputer 25 and the result is stored in a memory 32 and displayed on a display 27. In calculating a time T2' of used tape for one reel revolution through the similar operation to a tape at fast feeding, the time T2' is theoretically contained within a range given by formula II independently of the thickness of the tape. If the time T2' is discriminated as it exists outside of this range of formula II, the computer 25 displays T2+4.7 or T2+11.1 depending on the time T2' on the display 27. This is the same for the case at rewinding, allowing to prevent an unnatural display such as inversed increase/decrease due to the fluctuation of the tape speed at fast feed and rewinding. Where r0 and R are respectively tape maximum diameter and a hub diameter and T0 is an overall tape winding time.

Title: Main spindle device for machine tool
Inventor: IKEDA NAOHIRO
IPC: B23B19/02
Filed: 1999-04-30
Abstract: PROBLEM TO BE SOLVED: To obtain considerable supporting ridigity and load capacity for bearing heavy cutting. SOLUTION: Plate springs 21 and 22 prevent the displacement of a movable sleeve member 7 in its diameter direction by strong rigidity, and also make the member 7 free from the movement in its axial direction by a bending property, and be supported by a housing 1. Consequently when a main shaft 2 is thermally expanded due to the heating of a motor and so on, the member 7 smoothly moves in the axial direction together with the shaft 2, to prevent hindrance due to the thermal expansion. The smooth movement of the member 7 in the axial direction as mentioned above gives the proper pre-load as design to a rolling bearing 4 by a pre-pressure spring 9.

IPC: G11B5/706
Filed: 1989-05-19
Abstract: PURPOSE:To obtain the magnetic recording medium having a high coercive force and high S/N by constituting a magnetic film of Co-Ni-Cr-Mo and specifying the amt. of the Mo to be added to a specific value or below. CONSTITUTION:The magnetic film is constituted of the Co-Ni-Cr-Mo and the amt. of the Mo to be added is specified to <=5atm.%. Hc increases largely and Br.delta decreases gradually with the amt. of the Mo to be added simply when the small amt. of the Mo is added. However, S/N is inferior to the S/N of the film which is not added with the Mo if the Mo is added at the ratio higher than 5at.%. Such tendency occurs in the decrease in signals by the gradual decrease of Br.delta, from which the preferable amt. of the Mo to be added is <=5at.%. The magnetic recording medium having the high coercive force and high S/N is obtd. in this way.
