Title: Time limit device
Inventor: NARITA TAKAYASU
IPC: G04G15/00
Filed: 1978-03-02
Abstract: PURPOSE: To simplify a comparison control mechanism by comparing the counted value of a time counter and the set time of a timer memory in response to the detection of the unit rise of the counted value of the time counter thereby to  accomplish the time limit control.  
     CONSTITUTION: The time, which is set in timer memories 4 to 6, is compared with the counted time of a counter 2 by means of a comparator circuit 7. When a coincidence takes place, the circuit 7 generates ON and OFF signals of time switch. The comparing operations of the circuit 7 are controlled through a unit rise detecting circuit 3, which is operative to detect such unit rise signals as are generated every 30 seconds by a ten second counter of the counter 2 for counting hour, minute, and ten seconds. As a result, the compared symmetry time becomes the hour and minute  only so that the circuit of the comparator control system can be simplified. In case  the ON and OFF signals of the circuit 7 are generated simultaneously, either of the signals are made predominant, or either of the signals, which are generated previously in the circuit 7, are judged by a compared result judging circuit 9 so that  the time limiting operations can by performed without any error.

Title: Warm air space heater
Inventor: UEHARA KAZUHITO
IPC: F24H3/04
Filed: 1988-02-04
Abstract: PURPOSE:To make it possible to ensure a stable combustion by stepwisely pushing parts provided with a large number of holes which form air suction ports toward the downstream side opposite to a filter. CONSTITUTION:A step pushing 18 which is a step lower is applied to the downstream of a suction port 17 for primary air for combustion to form space 20 between the port 17 and the filter, thus extremely reducing the area tightly attaching to the filter as shown by slant lines, when compared with the conventional case. As a result, the absolute quantity of primary air for combustion which has not flowed by the conventional method, increases, and clogging of the filter is not promoted without increasing the opening area of each hole 17a. Thus, the quantity of primary air to the burner is ensured and stabilization of combustion can be sufficiently attempted.

Abstract: PURPOSE:To press fit a tubular housing accurately and quickly to a predetermined position by forming an exhaust means for press fitting the tubular housing in a tubular bottomed support being outserted over the chassis thereby ensuring an exhaust channel at the time of press fit. CONSTITUTION:When a tubular housing 3 for securing a rotary shaft 14 is press fitted to a shaft support 2 being outserted over the chassis 1, the tubular housing 3 15 press fitted in the shaft support 2 with a washer 34 being inserted into the forward end part thereof.

Title: Brake device in folding machine for rotary printing machine
Inventor: YAMAUCHI MASUO
IPC: B41F13/60
Filed: 1987-02-06
Abstract: PURPOSE:To make it possible to drive a rotary printing machine at a high speed without the sheet being slipped or folded in its back, by providing a pair of rollers which face each other with a predetermined space therebetween across a path for pull-out binding to be conveyed. CONSTITUTION:When a folding machine is operated, a pull-out binding 11 clamped on a discharge table 7, is conveyed toward a sheet discharge fan 12, passing through between brake rollers 20, 31. When the pull-out binding 11 is further moved, the trailing end of the binding binding 11 is clamped between a brake 22 and a rubber ring 32. Then, the binding 11 slips on the discharge table 7 so that it is retarded down to a speed equal to the rotational speed of the brake rollers 20, 31. When the binding is further moved, it is dropped into the sheet discharge fan 12 in a retarded condition. With this arrangement in which the moving speed of the pull-out binding is shifted into the discharge fan 12 at a retarded moved speed, the inertial energy may be reduced, thereby it is possible to prevent misalignment and back-folding due to leap-up of the pull-out binding 11.

Abstract: PURPOSE:To prevent the generation of a defective shape by forming the etching rate of the central section, where dicing prearranged regions cross, at value smaller than other sections and etching a wafer. CONSTITUTION:The etching rate of the central section 6 of the crossed section 3x'y' of regions such as the dicing prearranged regions 3x', 3y' is formed at value smaller than other sections.
