Title: Laser hazard preventing mechanism
Inventor: SAWANO SATARO
IPC: G02B6/26
Filed: 1989-06-07
Abstract: PURPOSE:To obtain the laser hazard preventing mechanism which is extremely excellent in operability and safety by providing a couple of French door bodies which are returned by a specific energizing member to their closing position to impede a laser optical path when an outside optical connector is disconnected. CONSTITUTION:When the outside optical connector 53 to be connected optically to a fixed-side optical connector 50 is inserted along the optical path of laser light, door bodies 2a and 2b are pressed by the connector and opened right and left symmetrically about the laser optical path, which is opened. When the outside optical connector 53 is disconnected, on the other hand, the door bodies 2a and 2b are returned by the energizing member and a light shield member 6 positioned on the laser optical path when the door bodies 2a and 2b are at their closing positions is formed on one door body 2a, so the laser optical path is cut off immediately and completely. Consequently, the danger of laser light to an operator is securely reduced or precluded in safety.

Title: Electronic brake system with system test
Inventor: MARUKOMU BUREARII
IPC: B60T8/17
Filed: 1994-06-24
Abstract: PURPOSE: To test a braking system to be transmitted to a load sensing brake in the condition that a vehicle is at rest or almost at rest by automatically applying predetermined normal brake input requirement to a test mode to produce compensating brake pressure in consideration of an effective value for axle load in the condition that the vehicle is at rest. CONSTITUTION: When a vehicle is sensed to be at rest, an electronic braking system is changed over to the operation of a controller. With this change-over, all control channels are changed over to a test mode in package so that a total control system is subjected thereunder. Brake pressure corresponding to fixed brake requirement DF is produced by each wheel brake actuator. The brake pressure is monitored by a pressure gage which is provided on a wheel brake line for this purpose. In this way, uniform axle load for resulting axle brake pressure can be produced and so accurate operation of an electronic air pressure system can be checked.

Filed: 1991-05-20
Abstract: PURPOSE:To improve data reading performance and access speed by improving positioning accuracy. CONSTITUTION:Position information data sampled by a magnetic head 3 based on a read signal is subtracted from a positioning target value V commanded from a host controller by a microcontroller 12 to obtain a deviation D, and being based on the deviation, a commanding amt. is calculated, and an offset amt. obtained on the basis of a previous commanding amt. is added to the above calculated commanding amt., and the added amt. is multiplied by a software gain Ks 17 and a current commanding value is outputted, and then the current commanding value is multiplied by a circuit gain Kc 19 to be converted into a current I and supplied to a VCM 5.
