Title: Defoaming agent for organic solvent
Inventor: OKADA FUMIO
IPC: B01D19/04
Filed: 1985-09-26
Abstract: PURPOSE:To obtain the titled defoaming agent capable of controlling frothing in an org. solvent wherein a surfactant is dissolved by using an organopolysiloxane contg. 20-70wt% fluorine and contg. a perfluoroalkyl group. CONSTITUTION:The defoaming agent consists essentially of an organopolysiloxane shown by the formula, contg. 20-70wt% fluorine and contg. a perfluoroalkyl group. The balance can be composed of a usual siloxane unit. The solubility in an org. solvent of the organopolysiloxane having <20cS viscosity is increased and the defoaming property is detriorated. Accordingly, the viscosity at 25 deg.C must be regulated to >=20cS and the agent can be solid at ordinary temp. The agent can be directly added to an org. solvent to be treated or 2-50wt% agent is dissolved in a ketonic or a halogenous org. solvent and the soln. is used.

Title: Dynamic damper
Inventor: HAMADA MASAAKI
IPC: F16F15/12
Filed: 1988-08-27
Abstract: PURPOSE:To miniaturize a dynamic damper maintaining the essential performance of the dynamic damper by arranging a cylindrical mass member inserted in a rotary shaft between a pair of annular fixing members and integrally connecting them by an elastic member. CONSTITUTION:When a drive shaft S is rotated and a harmful vibration is excited, the mass member 12 of a dynamic damper 1 to which characteristic frequency is adapted resonates. Although the characteristic frequency is adjusted by changing the shape of the elastic member 13 fixed by a fixing member 11, the length of the elastic member 13 from the position where the elastic member 13 leaves the outer circumferential surface of the shaft S to the end section of the thick steel pipe of the mass member 12 is substantially affected. That is, the longer the length is, the lesser becomes the coefficient of a shear spring and the lower the characteristic frequency becomes. On the contrary, the shorter the length is, the higher the characteristic frequency becomes. The dynamic damper 1 resonates the mass member 12 to absorb vibration energy so that harmful vibration may be controlled.

IPC: G11C16/12
Filed: 1981-12-26
Abstract: PURPOSE:To generate the writing/reading potential by means of a complete CMOS process, by forming a potential changeover switch with an enhancement type transistor to which a substrate electrode is connected in a prescribed way. CONSTITUTION:When the potential of a node 24 is set at a high level, the output of an inverter 90 having the prescribed threshold voltage is set at a low level with the output of an inverter 34 set at a high level respectively. Thus a potential changeover switch is formed. Then an enhancement type transistor 221 to which a substrate electrode and writing high potential are connected and an enhancement type transistor 23 to which a substrate electrode and an output node 5 are connected with a current path cut off with adjustment of the bias voltage and with a connection secured to the reading voltage VCC are turned on and off respectively. The writing high potential VPP is generated at the node 5. The reading potential VCC is generated in the same way without using a depression type transistor. Thus the writing/reading potential is generated with on-chip and by switching through a complete CMOS process in which the photoetching processes are decreased with the saved power.

IPC: F16H59/54
Filed: 1988-08-30
Abstract: PURPOSE:To miniaturize an oil pump and improve the fuel consumption by controlling the input torque transmitted from a torque converter to an oil pressure type automatic transmission less than the prescribed value when the stop of a vehicle is detected. CONSTITUTION:When a brake detecting signal is input from a brake detecting switch 88, a control unit 78 excites the electromagnetic solenoid of a stopper mechanism 89, and a stopper pin is displaced to the projecting position so as to prevent the operating movement of an accel pedal to the full open position, and the input torque transmitted from a torque converter to a continuous transmission is controlled to be the prescribed value.

Consequently, the line pressure can be restrained lower so that the structure of an oil pump for attaining to this line pressure can be miniaturized.

Title: Copper brazing method for heat exchanger
Inventor: KISHIKAWA RYOJI
IPC: B23P15/26
Filed: 1995-08-01
Abstract: PROBLEM TO BE SOLVED: To prevent a crack in a pipe base metal caused by brazing a cooling pipe and fins and thus a leak of cooling water. SOLUTION: A surface of a cooling pipe 1 and fins 3 is plated with Ni to form a Ni-plated layer 4 and the cooling pipe 1 and the fins 3 are provisionally assembled and brazed with copper.
