Title: Brake and stop device of truck used in forced stream type transporting equipment
Inventor: YAMAGUCHI TOORU
IPC: B65G51/08
Filed: 1979-08-21
Abstract: PURPOSE: To provide free hand to control the move of trucks to be separated from a air transport pipeline by generating, by the use of an air circulator, an other air stream than the forced stream in air transport pipeline, in a pipeline provided for braking and stopping the trucks.  
     CONSTITUTION: A truck 1 comes into a pipeline for braking and stopping turcks 3 from the air transport line 2, and further proceeds to a suction hole 9b in the bypass line 10 by the aid of a forced stream produced by a pump P 2  and stops there. When the truck sensor S 1  senses off that the truck has reached the suction hole 9b the pump P 2  is stopped, and the truck 1 is stopped by an air cushion formed between the truck 1 and a shelter 4. When the pump P 1  is operated by opening the shelter 4, the truck 1 moves into the space formed between the shelters 4, 4A by blowing action of the discharge hole 5a and sucking action of the suction hole 5c. When the sensor S 2  senses off that the truck has come in, the shelter 4 is closed and the truck 1 is transfered to the working part for trucks 7 by opening the shelter 4A.

Title: Magnetic card recording method
Inventor: MAENO TAKASHI
IPC: G11B5/80
Filed: 1989-04-28
Abstract: PURPOSE:To prevent a magnetic card from forging by recording plural tracks of the magnetic card with their respective information independently and making a specific relation regarding a relative position between specified two bits of information on their different tracks. CONSTITUTION:With regard to the 1st track and the 2nd track to be recorded with magnetic information independently of each other, write positions for 1st bit, N1-th bit and N2-th bit, etc., are set in their effective recording ranges L respectively. Then, differences (a), (b), (c)... are made between write positions corresponding to each bit on both tracks. When this constitutive magnetic card is to be used, the genuineness of magnetic card is discriminated by deciding whether the aforementioned differences (a), (b), (c)... are conformed with present values or not. Consequently, even when the information of the card can be read out, the aforementioned differences (a), (b), (c)... are unknown, so that there is no fear of a counterfeit by writing new information, etc.
