Patent JP-H08126947-A (JP)
Title: Holder spindle
Inventor: KOJIMA HIDEO
IPC: B24B13/00
Filed: 1994-01-12
Abstract: PURPOSE: To stably process even a work piece which has to be processed under low processing pressure by holding a holder holding a work piece in such a way as to be freely rotated with respect to a pressing shaft, and also freely moved in the axial direction, and also providing a pressing means pressing the holder to the direction of a tool bowl. CONSTITUTION: A support arm 13 is moved downward so as to be stopped in such a way that a work piece L is brought in contact with a tool bowl 14, a pressing shaft 9 is pressed by a pressing means 12, and the tool bowl 14 is rotated and rocked so as to allow the work piece to be processed. In this case, the pressing force of the pressing means 9 is applied to the pressing shaft 9, since only pressing force by a spring 7 is applied to the work piece L, low pressing pressure is just applied to the tool bowl 14.  Besides, since resistance for the work piece L to be moved up and down will be only frictional resistance between a housing 5 and a spindle case 6, the work piece can be very smoothly moved up and down, the work piece L very sensitively reacts against the movement of the processing surface 14a of the tool bowl 14, and absorbs vibration, and furthermore, it is processed while being closely attached thereto at all times.

Title: Solid-state laser device
Inventor: ISHIKAWA KEN
IPC: H01S3/131
Filed: 1984-02-16
Abstract: PURPOSE:To ensure a continuous, stable output characteristic even in the presence of a plurality of laser materials different in ion density by a method wherein the quantity of light to be thrown upon laser materials is adjusted minutely an adjusting circuit so that the quantity to be projected may be adapted to reflect the ion density of a given laser material. CONSTITUTION:The arc lamp is switched ON of each of several solid-state laser units, and voltage-setting rheostats 26a, 26b are adjusted so that the quantity of light projected by an arc lamp upon a laser rod may be equal to a preset value. When there is a rise in temperature in a laser rod, difference due to the lens effect grows prominent. This causes saturation in the high output region induced by the failure of the laser beam to pass through the gaps between laser rods. The difference is balanced by presetting the quantity of light to be applied to the respective laser rods, which is effected by operating adjusting circuits 19a, 19b so that the difference in lens effect attributable to the difference in the ion density of the respective laser rods cancells each other out. Consequently, a laser output characteristic is obtained continuously and in stable manner throughout the range of output from low to high.

Title: Optical pickup device
Inventor: TAKIGUCHI HARUHISA
IPC: G11B7/126
Filed: 1984-02-14
Abstract: PURPOSE:To reduce the level of noise caused by the feedback of the laser output light by applying a deep pulse modulation to a semiconductor laser having a reduced reflection factor on its output end face. CONSTITUTION:The output extraction factor of a semiconductor laser 1 is improved by setting the reflection factor at <=10% for a resonance surface for extraction of output and also at >=90% for a counter resonance surface respectively. a pulse generator 8 is connected to the laser 1 via a capacitor; while a light emitting diode 9 is connected with branching to the drive circuit of the laser 1 and then to an output circuit 11 via an LPF10. Therefore a DC current flows to the laser 1 from the circuit 11 in response to the signal given from the diode 9. Then a pulse current given from the generator 8 is superposed on the DC current of the laser 1. Thus the laser 1 is driven. This suppresses the fluctuation of the optical output of the laser 1 due to the feedback of reflected light and then reduces the noise level.

Title: Apparatus for detecting skew of paper sheet
Inventor: KAN TOMIO
IPC: B65H7/08
Filed: 1981-02-27
Abstract: PURPOSE:To make positive skew detection possible by a machine for arranging sheets of paper such as bills, in which machine the skew value of the sheets is determined based on a length of a side calculated from counted values of a plurality of light projector and receiver outputs normal to a conveying path. CONSTITUTION:A sheet P of paper is conveyed, and as the sheet shuts successively off the light receivers 17-11, counters 27'-21' start successively counting. A CPU40 selects the counter 21' by a selector 30, and detects the shutting period between the light receivers 17, 11 to find a skewed distance la according to the prescribed equation and to find a skew value theta deg. from a distance lb between the light receivers 11, 17. The correctness thereof is determined as follows: counted values of the counters 21-17 are selected to find the lengths in the conveying direction, the maximum value thereof is defined as a length L of one side of the sheet, and if Lmin<=L<=Lmax, it is judged that the calculated skew value theta deg. is correct. In case there is fold, the L corresponding to the light receiver 11 or 17 would not satisfy the formula, and therefore it is judged that the theta deg. is not correct.

Filed: 1998-02-10
Abstract: PROBLEM TO BE SOLVED: To avoid unnecessary blocking by identifying the fault of an optical disk drive device or the fault of an optical disk medium and blocking only the fault of the optical disk drive device. SOLUTION: Error information is received and it is judged to be the fault of an optical disk transportation device (101 and 102). When an error is outputted from an optical disk drive device, a used optical disk is extracted, a test optical disk is set and ECC checking is turned off (103, 104 and 105). Data of the optical disk is read and the optical disk is extracted (106 and 107). Data of the optical disk is previously recorded in a work station and it is read (108). Data obtained in processings 106 and 108 are compared (109). When data are not matched, data of the optical disk cannot precisely be read. Thus, possibility that the fault exists in the optical disk device is high and the drive device is blocked (110).
