Title: Servo off preventing device for magnetic tape device
Inventor: SHIMOZAKA HIDEAKI
IPC: G11B15/02
Filed: 1990-03-20
Abstract: PURPOSE:To secure the power required for the execution of the control of a control system and to prevent servo-off by reducing the rotational speed of a supply reel motor and that of a take-up reel motor at the time when the supply reel motor and the take-up reel motor are operated at a high-speed running. CONSTITUTION:An operation switching circuit 17 switches the control from a normal speed controller 14 to a high-speed running controller 18 by a rewinding operation instruction. A tension sensor 16 detects the fluctuation of tension due to the supply voltage, and the high-speed running controller 18 reduces a target speed and calculates a speed feedback current when the output of the tension sensor 16 is deviated from a prescribed range. This speed feedback current is added to the output of a tension controller by current computing elements with reel motors 10 and 11, and a supply reel motor 1 and a take-up reel motor 2 are driven and controlled by reel motor driving circuits 12 and 13, and the rotational speed is reduced. Thus, the counter electromotive force of the supply reel motor 1 and the take-up reel motor 2 is reduced, and the voltage required for motor control is secured to prevent servo-off in the case of the drop of voltage.

Title: Device for power steering system
Inventor: ROORENSU ERU MIRAA
IPC: B62D5/24
Filed: 1994-04-06
Abstract: PURPOSE: To allow an appropriate torque to be inputted in a steering system by connecting a first and second valve members to control the operation of a power steering motor to each other through a torsional tension spring. CONSTITUTION: A pair of hydraulic valve members 42, 46 which are relatively rotated to each other to control the operation of a power steering motor are elastically connected relative to each other. When the steering operation is started, the torque is applied to the torsional tension spring 52 to deform the torsional tension spring 52 in the twisting direction and in the axial direction. When the parking operation or a relatively high speed lane changing is implemented, the increment in the deformation in the axial direction of the torsional tension spring 52 to each increment of the relative rotation between the valve members 42, 46 is reduced when the angular displacement of the torsional spring 52 is increased. The extension force is effected to the torsional tension spring 52 by a cam surface to be engaged with both sides of a bearing element.  The extension force is transmitted to both end parts of the torsional tension spring 52 by the relative rotation between the cam surfaces and the torsional tension spring 52 is extended in the axial direction.

Title: Optical head
Inventor: YOSHIZAWA AKIHIKO
IPC: G02B6/12
Filed: 1991-04-01
Abstract: PURPOSE:To obtain a compact optical head to be easily formed by emitting a laser beam guided into a waveguide from plural divided gratings and setting up respective 1/2 wavelength plats so as to form prescribed angles with divided radiation beams. CONSTITUTION:Light from a laser diode 40 is converted into a circularly polarized light through a hologram element 36 and a 1/4 wavelength plate 33 and made incident upon the 1st grating (FGC) formed on a transparent base 31. The incident light is guided into an waveguide 32 and emitted so as to be converged by plural divided circular FGCs 25a, 25c arranged on the outside of the base 31. The 1/2 wavelength plates 34, 35 are arranged so that their optical axes coincide with the center polarizing direction of polarized beams radiated from the zone of several FGCs 25a, 25c. Consequently, the deflecting direction is rotated by 90 deg. and convergence can be attained in the matched state of the polarizing face. The converged beam is reflected on the recording face of an optical recording disk and returned through the reverse optical paths and focus error signals are obtained by photodiodes 37, 38. Consequently, the optical head can be compacted and easily produced.

Title: At-shifting hydraulic control device for automatic transmission
Inventor: MATSUMOTO AKIO
IPC: F16H61/06
Filed: 1993-03-26
Abstract: PURPOSE:To reduce shift shocks by decreasing the control oil pressure during a shifting gradually from the time an inertia phase is sensed, and thereupon controlling the incremental width of the output shaft torque with the gradually decreasing amount of oil pressure. CONSTITUTION:When one of the shift patterns takes place, the line pressure PL corresponding to the applicable shift is determined by the duty value of a duty solenoid valve which controls a regulator valve. The at-shifting line pressure PLn at this time is sunk from the line pressure PL0 outside of the shifting. When an inertia phase is entered where the substantial engagement of a friction element is started from the torque phase, a gradually decreasing width is added to the duty value, and the at-shifting line pressure PLn is decreased gradually. When the shift is ended, the line pressure PL is returned to the line pressure PL0 outside of the shift.

Title: Still picture transmitting method
Inventor: SATO NOBUHITO
IPC: H04N1/00
Filed: 1996-03-01
Abstract: PROBLEM TO BE SOLVED: To transmit a still picture always in a correct original size by transferring picture data and original size information of a still picture read by a reader. SOLUTION: An original of a size A4, e.g. on which the still picture to transfer is plotted is placed on the scanning part of a color copying machine 4 on a transmission side functioning as the reader, and the number of printing copies to transmit and resolution at the time of scanning the original are set by the key operation of a color still picture transmitter 2 to transmit. Then the color copying machine 4 receiving the printing instruction of a receiving side terminal prints a received picture according to original size information, data on the number of printing copies and resolution. As original size information obtained by scanning the still picture by the reader is transmitted with picture data like this, it is prevented to transmit picture data because of the specifying of a wrong original size. Consequently, an operation cost and a communication cost are reduced.

Filed: 1989-03-20
Abstract: PURPOSE:To enable the detection of minute metallic contamination and the separate evaluation of a surface and a bulk by a method wherein the life time of a semiconductor material is measured as it is made to change in temperature. CONSTITUTION:A heat resistant member 4 in which a heater 7 is buried is mounted on an XY table 6, and a non-metal heat-resistant member 2 is placed thereon. A test semiconductor material 1 is put on the heat resistant member 2 and irradiated with a microwave emitted from a microwave transmitting and receiving waveguide, and concurrently exciting light rays are outputted from laser diodes 51 and 52. When the life time of the semiconductor material is measured by a reflected microwave making the semiconductor material 1 rise gradually in temperature through a heater 7, a non-diffused sample is made to increase in life time at a certain temperature or above, but on the other hand a diffused sample increases very slightly in life time. By this setup, the identification of very small metallic contamination, the conjection of a kind of the metal concerned, and the separate evaluation of the surface and the bulk can be made.

IPC: H01S3/101
Filed: 1989-03-20
Abstract: PURPOSE:To prevent the thermal deformation of a shutter by a method wherein an atmosphere on the surface of a substrate to be treated is moved in parallel to the substrate surface at a constant flow rate and the shutter is installed more backward than a beam expander and a power adjusting device to make uniform the irradiation of a laser beam. CONSTITUTION:A laser beam emitted from a laser 1 is reflected by a galvanoscanner 6 via a beam expander 3, a lambda/2 plate 5 and a shutter 21 and is irradiated on a wafer 9 via an ftheta lens 7. N2 gas is flowed at a constant flow rate in parallel to the surface of an installment stand 11 from introducing tubes 13a and 13b toward exhaust tubes 13c and 13d. Thereby, the meandering of an irradiation beam due to a convection, which is generated by heating the stand 10 by an infrared lamp 11 at 500 deg.C, is prevented. Moreover, as the shutter 21 is installed more backward than the expander 3, the thermal deformation of the shutter 21 is prevented.
