Title: Trailer brake in electronically controlled brake system
Inventor: MARUKORUMU BUREARII
IPC: B60T8/176
Filed: 1989-11-20
Abstract: PURPOSE: To reduce a delay to a maximum until the brake of a trailer is rendered effective by a method wherein an electric signal representing the braking demand of a driver is processed such that a predetermined amplitude supplementary pressure prepulse is generated. CONSTITUTION: A trailer channel controller 48 sets a trailer brake pressure to a line 46 from the braking demand of a driver. Further, a subsystem containing a trailer control channel is disposed such that, when a brake of a vehicle is demanded through an electric signal, a pressure pulse in-shot is substantially immediately fed to a trailer brake circuit and a mutual coupling line 46 between a traction vehicle and a trailer in a manner to answer before the brake of the traction vehicle is practically used. The pressure in-shot or the prepulse is fed by an electropneumatic control valve, and since a valve applies a pressure on the trailer brake circuit in a short time as much as possible, a preset high pressure is generated at the line 46 limited to only a piping.

Title: Dial type lock
Inventor: KATADA MASUO
IPC: E05B41/00
Filed: 1995-10-30
Abstract: PROBLEM TO BE SOLVED: To prevent misoperation in dial setting by furnishing a lock box with a locking check mechanism working in association with the rotational control operation of a key lever. SOLUTION: Any object is accommodated in place, for example in a locker, and the pass number is input from a dial 12, and a key lever 1 is turned to the position of Close 16 while a push button 10 is pushed. This causes simultaneous rotation of a cam plate 19 to generate engagement by a detention part, and when the pass number is altered to any other by turning the dial 12, the perfect locking is established. Even when one alters pass number to any other by mistake after the first setting and turns the key lever 1 to the position of Close 16 directly without pushing the button 10, the key lever 1 will never turn to that position from the position of Open 17 because the cam plate 19 is fitted in a recess provided in a rotational control disc. Accordingly he will notice that he is committing mistake, and it is possible to make correct locking at all times.
