Title: Preparation of pseudoirone
Inventor: MIYAWAKI HIDEAKI
IPC: C07C49/203
Filed: 1983-07-07
Abstract: PURPOSE:To prepare the titled compound useful as a precursor of perfumery, easily in high yield, by selectively reducing 4-methylisopiperitenone, thermally decomposing the product, and reacting with acetone in the presence of caustic alkali, thereby carrying out the isomerization and condensation at the same time. CONSTITUTION:4-Methylisopiperitenone of formula IV is reduced with a reducing agent such as hydrosilane, etc. in the presence of a catalyst such as aluminum alcoholate, phosphine-rhodium complex, etc. to effect the selective reduction of the carbonyl group of the alpha,beta-unsaturated ketone. The obtained 4-methylisopiperitenol of formula III is thermally decomposed at 300-450 deg.C to obtain a mixture of 6-methyl citral of formula IIa and 6-methylisocitral of formula IIb. The mixture is made to react with acetone in the presence of a caustic alkali. The isomerization and the condensation take place simultaneously to obtain the objective compound of formula I useful as a precursor of irone compound which is present in the essential oil of orris root and is an excellent violet perfume.

Title: Pulse generating circuit
Inventor: MIZUTANI HIDETOSHI
IPC: H03K3/023
Filed: 1989-05-16
Abstract: PURPOSE:To obtain a pulse generating circuit with high accuracy whose pulse width is easily set to a desired value by correcting a potential at a connecting point between a resistor and a capacitor and making a pulse width of a generated pulse close to a theoretical value. CONSTITUTION:A connecting point A is thrown to the position of an inverting input of a comparator 11, a reference potential PL is inputted to a noninverting input, its output is given to an N-channel gate of an analog switch 12 and connects to a P-channel gate via an inverter 14. Then the power potential divided by resistors 15, 16 connects to the connecting point A via the analog switch 12. The resistance of the resistor 15 is set smaller than the resistance of a resistor 1. When a potential VA of the connecting point A reaches the reference potential VL, the output of the comparator 11 is inverted to turn off the analog switch 12, then the power supply 13 and the connecting point A are electrically interrupted. Thus, a pulse width close to a theoretical value set by the resistance of the resistor 1 and a capacitance of a capacitor 2 or the like is obtained.

Title: Sample and hold circuit
Inventor: NAGAISHI HIROMI
IPC: G01R13/34
Filed: 1985-06-07
Abstract: PURPOSE:To obtain a stable sample and hold circuit of high-speed response by making the base potential of a transistor TR for load higher than the emitter potential and setting the base potential of a TR, which is connected to a constant current source, to the earth potential in the holding mode. CONSTITUTION:When the mode is switched to the holding mode, a power source voltage is applied to the emitter of a PNP TR T5 through a diode D1 to reduce the emitter potential from a power source voltage V<+> by the forward voltage of the diode D1. Consequently, the electric charge stored in the base of the TR T5 is discharged quickly to shorten the switching time of the TR T5. When a potential sufficiently higher than the earth potential is applied as a signal -phi to the base of a TR T9 to turn on this TR in the holding mode, the base potential of a TR T2 is approximately equal to the earth potential. Thus, TRs T1 and T2 are not destructed by extension of the range of the input voltage.

Title: Clutch release bearing device
Inventor: MOMOI SHINICHI
IPC: F16D23/14
Filed: 1987-05-21
Abstract: PURPOSE:To abate the extent of frictional wear in a clutch release bearing device by installing a case in a contact part between a hub, where a bearing is built in, and a fork, housing this case free of rotation, and making a ball contractible to the fork. CONSTITUTION:When a clutch is released, it comes into contact with a ball 3 being housed in a case 4 of a disklike member 11, while a fork 5 moving to the left floats the ball 3 as far as the flexible amount of an elastic-material- made seal lip 17 while rotating the ball. A hub 2 is lightly moved to the left as being guided by a sleeve guide, pressing a diaphragm spring, and it releases the clutch. In this state, a bearing part 1 races. Thus, sliding motion is converted into rolling motion so that reduction in frictional wear is well promoted.

IPC: D06F39/08
Filed: 1999-04-28
Abstract: PROBLEM TO BE SOLVED: To provide a washing machine which can detect precisely the flow rate of supplied water without installing a water-level sensor. SOLUTION: This washing machine has a pressure sensor 40 using an ultra- magnetic deformation element in a suspension-stick receiver metallic material 15 which fixes a suspension stick 3, and detects by the pressure sensor 40 the weight of the washing accepted in a washing and dewatering tank 4 and the weight of the supplied water. At the time when a bath-water pump 18 is actuated and a water-supply valve 16 is opened, an increase of the prescribed weight is detected according to the detection signals of the pressure sensor 40, and the flow rate of the supplied water is estimated by measuring the time required for the increase. Since such measurement is not affected by loads and cloth quality of the washing, the flow rate of the supplied water can be obtained precisely.
