Patent JP-H06154908-A (JP)
Title: Punch press
Inventor: HAYASHI SHIRO
IPC: B21D28/36
Filed: 1992-11-16
Abstract: PURPOSE:To provide a punch press which prevents the damage and deflection of direct acting guides by impact at the time of punch press working and is miniaturized. CONSTITUTION:Bolsters 5 provided with an upper die 25 and a lower die 33 and a striker 27 are provided on side frames 21 and since the bolsters 5 are supported freely slidably by the direct acting guides 7, reaction force of the press at the time of working is offset in the side frames 21 and not transmitted to the direct acting guides 7. In addition, since direct acting blocks 11 of the direct acting guides 7 are restricted only in the crosswise direction by direct acting rails 9 and free in the upward direction, even if the lower ends of the side frames 21 are bent and deformed by the reaction force at the time of working, deformation is absorbed by lifting the direct acting blocks 11, hence excessive force is not acted on the direct acting blocks 11.

Title: Multiple dwelling hous monitor and telephony system
Inventor: HISAMATSU NOBUO
IPC: H04M9/00
Filed: 1995-11-24
Abstract: PROBLEM TO BE SOLVED: To give priority to calling and to prevent the operations of both an alarm monitor board and a fire alarm from overlapping with each other by outputting only a ringing tone from a speaker and inhibiting the output of the fire alarm when there is a call from the alarm monitor board or lobby interphone during a test of operation from the outdoors. SOLUTION: A house information board 1 enables the operation test while receiving an in-test signal, but interrupts the operation test and generates the ringing tone when there is a call from the alarm board or lobby interphone. If an actual fire takes place, a remote tester 6 received the alarm signal of a fire sensor S through a sensor line Ls, breaks a contact SW2 of a repeater 3 with a test terminal to cut off the output of the in-test signal, and forcibly switches a contact SW1 to connect the sensor line Ls to the house information board 1. Consequently, the house information board 1 is disconnected from the in-test signal and judges that an alarm signal received by a fire receiving circuit is caused by the actual fire, thereby outputting an alarm sound from a speaker.

Title: Network print system, information processor, print server, print controller, its method and storage medium storing control program
Inventor: WANDA KOICHIRO
IPC: B41J29/38
Filed: 1997-11-07
Abstract: PROBLEM TO BE SOLVED: Not to make communication for data transfer needlessly long and to confirm a print end till ejecting paper of a printer through a few communication lines by making a server eliminate job information of print data which is notified that printing is finished by a notifying means. SOLUTION: A virtual server 101 always monitors the status of a network printer 105 and also acquires an identifier of a job which identifies a job that finishes printing and the number of pages that finish printing through polling of a fixed interval. When an identifier of a job of a client PC 104 is returned as an identifier of a finished job in response to an end notice request to the printer 105, the server 101 sends an elimination instruction to the PC 104. The PC 104 eliminates the job and notifies a result to the server 101. The server 101 that receives elimination result notice, eliminates job information from a queue and returns to a regular state.

Title: Fire grates of garbage incinerator
Inventor: UYAMA HAJIME
IPC: F23G5/00
Filed: 1991-11-22
Abstract: PURPOSE:To change the amount of incinerated article to be carried on the same fire grate arbitrarily. CONSTITUTION:Fixed fire grates 2 laid out alternately with movable fire grates 3, are displaced to transfer directions A and B of the movable grates 3 so as to control the amount of projection Lfi of the movable fire grates 3 which projects from the top of the fixed fire grates 2. The amount of projection of a dry fire grate on the upper stream side is arranged to be smaller than that on the down stream side, which increases the amount of carrier on the down stream side and prevents an incinerated article from dropping to the combustion fire grates in bulk. It is also possible to reduce the amount of carrier on the down stream side and prevent the generation of blow-by by reducing the amount of projection on the down stream side on a rear combustion fire grate smaller than that on the upper stream side.
