Title: Mechanism for elevating pallet in insert molding machine
Inventor: KODAMA KAZUHIDE
IPC: B65G47/14
Filed: 1988-09-29
Abstract: PURPOSE:To make it possible to stop perfectly a table having been lowered just after it starts to go up again by providing a limit switch positioning an original point at a point a little higher than the position of a lower limit switch. CONSTITUTION:Stop positions of a table 19 are divided into an original position which is a standard for stop and a controlled stop position where it stops in coinciding with a position of a pallet 7. The original position is detected by means of a limit switch for the original point provided at a little higher than the position of a lower limit switch 21. The table 19 which has been lowered and starts to go up again is stopped at the original position, where exchange of a magazine 8 is performed. When the table is going down, the acceleration of gravity acts on the table 19, and so called, a back rush phenomenon wherein the table passes by the stop position, occurs, but when the stop position is set on the elevating process, the gravity acts so as to control this back rush and the accuracy of stopping can be improved. Therefore, it is possible to perform accurately the positioning of the pallet and to attempt to improve the stable quality of a product.

Title: Load control device
Inventor: MORITA MASAYUKI
IPC: H04Q9/00
Filed: 1987-09-30
Abstract: PURPOSE:To prevent the signal output means circuit of a slave unit to be destroyed by outputting a short-circuit signal with the aid of a short-circuit detection means when short-circuiting occurs between a load circuit and the signal output means and stopping the output of the slave unit with the aid of a short-circuit control means. CONSTITUTION:When the short-circuiting occurs between the illumination load circuit 22 and the signal output means 11, the short-circuit signal is outputted by conducting a Zener diode 24, a light emitting diode 26 is lighted, a phototransistor 27 is turned on and the short-circuit signal is outputted to the short-circuit control part 8. The short-circuit control part 8 stops outputting by turning off the light emitting diode 13 of the short-circuit channel of a light adjustment control signal generation part 7 and stops the output of a light adjustment control signal from the signal output means 11 of the corresponding channel when the short-circuit signal is inputted. Thus the signal output means is not destroyed even when the short-circuiting occurs between the load circuit and the signal output means.

Filed: 1998-09-01
Abstract: PROBLEM TO BE SOLVED: To electronically realize a book advertising and selling system which gives a feeling of stand-up reading equal to that at an actual store. SOLUTION: At a request to browse a book from a customer terminal 2, an advertising and selling computer 1 requests the customer terminal 2 to send the ID of the customer out. When the customer inputs the ID given by an advertising and selling company through an ID providing means 21, an authenticating and communicating means 14 authenticates it and a distribution restricting means 13 imposes temporal and opportunity restrictions when distributing book data to the customer terminal 2. For browsing, the book data ciphered by a compressive encoding and ciphering means 11 are distributed to the customer terminal 2 together with a signal allowing cipher resetting and stored in a storage device 23.  In this case, a cipher resetting means 24 and a compressive encoding resetting means 25 functions and the data can be browsed on a display device 28 through an display image generating means 26. Once the customer decides its purchase, the advertising and selling computer 1 outputs an 'output allowing signal', so the cipher-reset book data can be stored in the storage device 23 through an output means 27.
