Title: Tone concentration controller
Inventor: MARUMOTO TAKESHI
IPC: G03G21/00
Filed: 1990-03-19
Abstract: PURPOSE:To realize a toner concentration controller which is short in the stop time for a toner concentration recovery by stopping recording operation for a short time which is set previously every time one-sheet recording is completed if toner concentration falls below a stop level in multi-consumption mode. CONSTITUTION:When the toner concentration detected by a toner concentration sensor 1 is between a control level and an empty level, continuous recording is carried out while toner is supplemented.

Title: Semiconductor device
Inventor: ENDO KATSUHIRO
IPC: H01L21/52
Filed: 1988-03-24
Abstract: PURPOSE:To bond the whole surfaces of sections between a semiconductor substrate and a support board with a solder material, and to prevent the adhesion of the solder material onto the substrate or the side face of the support board, by providing a groove for a solder- material reservoir surrounding a brazing region to a brazing surface between the semiconductor substrate and the support board. CONSTITUTION:Grooves 6 are shaped to an exposed surface on the substrate side of a support board 2 having an area larger than an silicon substrate 1, a brazing region with the silicon substrate 1 is surrounded, and an excess solder material 3 not used for brazing the substrate 1 and the support board 2 is collected in the grooves 6. Consequently, when the substrate 1 and the support board 2 are brazed while holding the solder material 3, a flow phenomenon to the side faces of the support board and a creeping-up phenomenon to the side faces of the substrate are not also generated because the remainder of the solder material 3 filling between the opposed surfaces of the substrate 1 and the support board 2 is introduced into the grooves 6 for a solder-material reservoir, and the usage of the solder material 3 in quantity where no shrinkage cavity phenomenon is generated is also ensured. Accordingly, adhesion to the undesired section of the solder material 3, the shortage of the quantity of the solder material 3 or the like are prevented, thus conducting sound brazing with excellent reproducibility.

Title: Flash fixing device
Inventor: TANAKA EIJI
IPC: G03G15/20
Filed: 1980-05-28
Abstract: PURPOSE:To improve fixation effect, by heating toner or a recording body before fixation by using heat from a lamp and a reflecting plate. CONSTITUTION:As flash fixation is repeated by a device, internal-surface reflecting plate 10 is heated by energy radiated by a lamp 4 and the temperature of a cooling wind rises according to the temperature of the plate. As the temperature of the cooling wind rises, the temperature of toner or a recording body heated at the circumference of a blow outlet 13 also rises. When the toner and recording body are at high temperatures, the fixation is done by less fixing energy. Namely, the efficiency of the fixation after heating increases.

Title: Clutch hydraulic control device
Inventor: ASAYAMA YOSHIO
IPC: F16D48/02
Filed: 1987-03-25
Abstract: PURPOSE:To make it possible to simply and surely detect the completion of filling by detecting the motion of a spool in accordance with the presence of oil flow into a clutch so as to determine the completion of filling. CONSTITUTION:A controller delivers a current value to a solenoid 14 upon start of a speed shift so to move a spool 13 leftward by a large degree, and after that the delivered current value is dropped to its original value to stand by for the completion of filling. Further, when the completion of the filling is detected, the current value is gradually increased. Thus,the motion of a spool 21 in a flow detecting valve 31 acts in dependence upon the presence of oil flow in the form of the contacting and separating motion of a piston 22 with respect to a cover 25. Accordingly, by electrically detecting the contacting and separating motion, it is possible to simply and electrically detect the completion of filling.
