Title: Substrate voltage generating circuit and semiconductor integrated circuit device
Inventor: KOBAYASHI MASAKO
IPC: H01L21/822
Filed: 1998-10-05
Abstract: PROBLEM TO BE SOLVED: To provide a substrate voltage generating circuit and a semiconductor integrated circuit device for ensuring reliability by using a transistor whose gate oxidized film thickness is thin regardless of a high voltage boosting level. SOLUTION: A semiconductor integrated circuit device includes an oscillator for generating a clock signal and a charge pump circuit 100. The charge pump circuit 100 includes capacitative elements C1-C5 and an output transistor Q6. The capacitative element C2 boosts the voltage of a voltage boosting nose (node N2). A transistor Q9 cramps the voltage level of the node N2 to a constant value. The capacitative element C4 controls the gate voltage of the output transistor Q6. Voltages on transistors Q4 and Q7 and a capacitor C4 are reduced by using a transistor Q9, and the generation of hot carrier is suppressed.

Title: Fin-and-tube type heat exchanger
Inventor: FUJIMOTO KAZUHISA
IPC: F24F13/22
Filed: 1996-10-25
Abstract: PROBLEM TO BE SOLVED: To prevent dew condensation water produced on an upward-directed long side of a tilted fin of a heat exchanger from flowing down along the upward-directed long side of the fin, jumping to a machine body in the vicinity and leaking outside the machine body, in the case when the hydrophilic property of the fin deteriorates.

Title: Rotary recorder
Inventor: KIMURA TETSUO
IPC: H04N1/04
Filed: 1986-11-28
Abstract: PURPOSE:To permit high speed recording action, and compact and light-weight of a structure so that a sheet may be cut under a small and light-weight structure by providing a sheet transport means along part of the periphery of a rotary element and installing a sheet cutter on the rotary element or a member which rotates with the rotary element integrally. CONSTITUTION:The high- and low-level surfaces 14 of a circumferential cam 12 provided on the external periphery of a rotary element 3 are fitted to two grooves located adjacent to a driver roller 13. If cam 12 rotates in an arrow A direction, only the high-level surface 14 fits the groove. Further, if the cam passes through a gradient part 16, shifting to the low-level surface 15, a roller 13 is driven by rotation by groove pitch. Then if the roller rotates 350 deg., the surfaces 14, 15 fit the next groove. Consequently, if the rotary element 3 rotates, the roller 3 synchronously rotates each sheet feed roller 18 through a universal joint 17, feeding sheets. A sheet center 20 mounted on the rotary element 3 turns a solenoid 21 ON, protruding a blade 22 to a position which crosses the sheet. Thus the sheet is cut by utilization of the rotational motion of the rotary element 3.
