Title: Supersonic wave car
Inventor: HARIGAI NAOKI
IPC: B60R21/34
Filed: 1988-12-20
Abstract: PURPOSE:To indicate a danger signal with green and red and to sound an alarm as well as to stop an engine by transmitting supersonic waves and knowing an object approaching a vehicle from the coming back waves. CONSTITUTION:The object approaching the vehicle is known by transmitting the supersonic waves and detecting the sound waves returning therefrom. A supersonic signal transmitter and receiver 2 are provided on the right and left of the vehicle body. The danger that the vehicle or motorcycle approaches is announced by the right and left alarms 4. The vehicle detects the object traveling in front thereof by the supersonic transmitter and receiver 2 and the alarm 10 sounds from the front of the vehicle body. The brake is simultaneously applied. The transmission and reception of the supersonic waves can be canceled and inputted by a switch 5. The sounds of the alarms vary with the speed at which the object approaches. The sounds of the alarms are faster as the approaching object is faster.

Title: Stage apparatus and controlling method therefor
Inventor: MATSUBARA HISATO
IPC: G12B5/00
Filed: 1994-12-26
Abstract: PURPOSE: To provide a stage apparatus in which the own weight deflection of a plate can be alleviated. CONSTITUTION: The stage apparatus comprises a support pin for sucking to support a board P on a board stage, and a conveying arm 14 to support the board P to receive and deliver it from and to a board stage support pin. The pins are substantially concentrically disposed at a plurality of groups 4a, 4b, and an elevating motion and board sucking and releasing motions can be independently controlled at each group. Thus, since the supporting height and the sucking and releasing timings of the plate P can be altered at each of the groups 4a, 4b, the own weight deflection and intrinsic warpage of the plate P can be suppressed to the minimum limit while suppressing a stress to be given to the plate P.

Filed: 1996-12-04
Abstract: PROBLEM TO BE SOLVED: To suppress crosstalk to an adjacent track by recording/reproducing a test signal to obtain an optimal laser beam pulse width and intensity for recording and recording actual information under this optimal irradiation condition. SOLUTION: A magneto-optical disk is driven so as to position an optical head in the track of a desired address and a magnetic head in the vicinity of this track position. Then, when laser beam pulses P1 to P5 having various recording laser pulse widths are projected, a magneto-optical recording magnetic area is widened and made longer because of the pulse width increase. By tracking a beam spot in its adjacent land, a magneto-optical reproducing signal is produced for leaking-in of rest data. At this time, by using a level for not diving any influence on the adjacent track as a slice level,. a laser pulse width corresponding to a reproducing signal not exceeding the level is set as an optimal recording laser beam pulse width. Under this laser irradiation condition, actual information recording is carried out.
