Title: Image forming device
Inventor: MUROFUSHI TAKASHI
IPC: B41J13/00
Filed: 1996-02-28
Abstract: PROBLEM TO BE SOLVED: To recycle an undamaged transfer sheet whose one side has been recorded and, remaining in a carrying path at the time of jamming by ejecting the transfer sheet in the carrying path to a sheet feed tray used exclusively for transfer sheets whose one sides have been recorded. SOLUTION: When jamming occurs during a consecutive copy using transfer sheets whose one sides have been recorded, a jamming detection sensor set in a proper part of the transfer-sheet carrying path detects the jamming, and stops the copying operation of an image detector. Then, the device judges whether or not a tray containing transfer sheets with images recorded on their one sides, whose sizes are matched with the size of the transfer sheet being copied exists among the sheet feed trays 3a-3c. When it exists, the carrying path is turned to the sheet feed tray by means of a sheet ejection place switching part 45.  At this time, for example, in the case the sizes of the stored transfer sheets are equal to that and the tray for the transfer sheets whose one sides have been subjected to recording, specified by the depression of a tray switch button, is 3b, the top of the transfer sheets in the sheet feed tray 3b moves down a specific distance, and the transfer sheet is ejected from an ejection roller 48b mounted on the sheet feed tray 3b.

Title: Induction hardening method
Inventor: MISAKA YOSHITAKA
IPC: C21D9/32
Filed: 1996-02-28
Abstract: PROBLEM TO BE SOLVED: To superiorly apply contour hardening to a material improved in machinability and inferior in hardenability. SOLUTION: A material to be heated is rapidly preheated by means of induction heating up to 1000-1200 deg.C at >=300 deg.C/sec temp. rise rate in a short time and then cooled slowly. Successively, this material to be heated is subjected to rapid regular heating in a short time by means of induction heating at >=1000 deg.C/sec temp. rise rate up to a temp. between 900-1050 deg.C and lower than the preheating temp., followed by rapid cooling. Because of the dispersion and distribution of C at the time of preheating, uniform austenitization at the time of regular heating can be facilitated and contour hardening can be applied even to the tooth-shaped article of a material with superior machinability and inferior hardenability, sufficiently.  Moreover, because heating temp. at the time of regular heating can be lowered, power unit load can be reduced, and further, crystalline grains can be made fine.

Abstract: PURPOSE:To keep the temp. of the end point of a packed endothermic reaction catalytic layer sufficiently high by providing a heat insulating layer to a partitioned cylinder part of an inner-outer double annular space which is partitioned with a partition cylinder and communicated in the lower end. CONSTITUTION:A catalytic layer consisting of an outer catalytic layer 10 and an inner catalytic layer 11 is heated by combustion gas fed from a burner 3 and a gaseous raw material which is allowed to flow through the catalyst to the direction reverse to the flow of this combustion gas is subjected to endothermic reaction in the catalytic action and changed into a gaseous reaction product. At this time, the high-temp. part of combustion gas gives heat to a reaction pipe 2 by radiation and the low-temp. part gives heat thereto by convection heat transfer. In this case, the largest temp. difference is caused in the end point and the starting point in which the catalytic layers are made adjacent in the adjacent part of the inner-outer catalytic layers 10, 11 according to the endothermic reaction. Since a heat insulating layer 13 arranged with a heat insulating material such as ceramic fiber is provided to this part of a partition cylinder 5, heat transfer is inhibited and high temp. necessary for the reaction is kept even near to the end point.

Title: Three-winding pulse transformer drive circuit
Inventor: ONO MASAHIKO
IPC: H03K17/00
Filed: 1986-03-25
Abstract: PURPOSE:To prevent the reduction in an output impedance by disconnecting a spike absorbing circuit of a pulse transformer when no pulse is sent. CONSTITUTION:In sending a pulse, the pulse is sent from the ternary winding T3 to output terminals 1, 2 with switches SW1, 2 closed. In turning off the pulse, the switch SW1 is opened at first, then the current is zero at this moment because the loop is opened and then the pulse is turned off. The switch SW2 is still turned on, however, then the transient current of the pulse transformer T flows through the switch SW2 and a diode D1 and the electromagnetic energy is discharged, in connecting the switch SW2 after a time T0, the pulse transformer T is disconnected completely from the power supply E. The drive circuit at the side of switches SW3, SW4 acts similarly. Thus, no induced current flows to the pulse transformer T by the voltage impressed from the line side.
