Filed: 1999-03-12
Abstract: PROBLEM TO BE SOLVED: To exhibit the effect of restoring hair by forming a cap opening in an expansible binding portion, forming an air chamber in the interior when attached and supplying warm air to the air chamber. SOLUTION: A binding portion is formed by fitting an expansible bag-shaped air band 2 at the open edges of a cap 1 and, when worn on the head, an air chamber 3 is formed between the cap 1 and the head. The outermost layer of the cap 1 is a double structure, and the space is partitioned into several air dwelling chambers 4, and many air outlets 5 are made in the insides of the air dwelling chambers 4. An air supply pipe is connected to the leftmost air dwelling chamber 4, and an air relief valve is attached to the rightmost air dwelling chamber 4. Warm air supplied through the air supply pipe flows in the air chambers 4 toward the air relief valve, in the meantime blowing into an air chamber 3 from the outlets 5, and provides a temperature stimulus and a cleaning effect to the head, thereby exhibiting the effect of restoring hair.

Title: Semiconductor read-only memory
Inventor: KAWAMOTO HIROSHI
IPC: G11C17/00
Filed: 1988-03-23
Abstract: PURPOSE:To speed up read access by crossing respective word lines with reference-voltage-supplying current routes. CONSTITUTION:The titled memory is constituted of plural, i.e., l-pieces of depression type n-channel MOSFETs whose gates are connected with word lines W1-Wl and whose respective sources and the drains of are connected in series with each other. Such a potential variation as corresponding to a potential variation which is supplied to a memory cell row corresponding to the level shifting of a word line, is supplied to the current routes in circuit blocks DLA and DLB. Subsequently, potential variation through capacitors are simultaneously supplied to the pair of input-output terminals of a sense amplifier SA1. The sense amplifier AS1 is virtually insensitive to a potential variation that occurs in such a balanced status as the above. Since a potential difference corresponding to a memory information in a memory cell is supplied to the sense amplifier AS1 without being disturbed virtually by such a potential variation through a capacitor as the above-mentioned, the action timing of the sense amplifier SA1 can be speeded up.

Abstract: PROBLEM TO BE SOLVED: To provide a power conversion system which restrains the generation of DC component of series capacitors and can ensure the margin angle of commutation in all valves. SOLUTION: AC terminals of a thyristor converter 3 which operates, in accordance with an ignition angle command and converts DC into three-phase AC or converts three-phase AC into DC are connected with an AC power source 7 through series capacitors Cu, Cv, Cw. DC components of the capacitor voltages of the respective phases which are measured with voltage detectors 91-93 are detected with a DC component detecting circuit 14. An ignition angle correcting circuit 13 which corrects the ignition angle command of the thyristor convertor 3, in accordance with the detected DC components is added to a control circuit. A phase control circuit 11 for controlling the ignition angle of each phase of the convertor 3 decreases the flow width of a phase of large capacitor voltage and increases the flow width of a phase of small capacitor voltage.  Thereby the DC component of capacitor voltage is reduced, and the unbalance in the commutation voltage of each phase is reduced.
