Title: High pressure metal vapor discharge lamp
Inventor: SUGIURA MINORU
IPC: H01J61/56
Filed: 1985-05-23
Abstract: PURPOSE:To realize a metal vapor discharge lamp of high start-up performance with both short breakdown time and short shift time to arc discharge, by applying higher-voltage lower-repetition rate pulses between electrodes in the earlier period for starting up a discharge lamp then applying there lower-voltage higher- repetition rate pulses. CONSTITUTION:With a commercial A.C. power supply applied to the circuit, a voltage wave form including higher-voltage lower-repetition rate voltage pulses appears across terminals A, B at first, since a parallel compound resistance value of current limiting resistances 5a, 5b of, for instance, 400OMEGA and 1,200OMEGA respectively is 300OMEGA. An insulation breakdown between electrodes of a light emitting tube is caused by these pulses first, then, after about 10sec a heat sensitive switch 6 is let off by self heating up of the current limiting resistance 5a. Therefore, only the current limiting resistance 5b remains for a lighting tube 7, applying a voltage waveform including higher-voltage lower- repetition rate voltage pulses between electrodes of the light emitting tube for a rapid shift to arc discharge.

Title: Recording medium for copying prevention
Inventor: TERASAKI HITOSHI
IPC: G11B7/24062
Filed: 1997-04-25
Abstract: PROBLEM TO BE SOLVED: To provide an optical disk for copying prevention by providing a signal recording surface having signals recorded by a pit string in one surface, forming a metallic layer contacted with the signal recording surface for covering the same and setting the thickness of this metallic layer to be larger than the depth of a pit depth. SOLUTION: A signal recording surface 2 having a signal recorded by a pit 5 is formed on one surface of a light-transmissive substrate 1, and a metallic layer 4 and a protective layer 4 which are made of Al are sequentially formed to be in contact with the signal recording surface 2. When the thickness of the metallic layer 3 is set nearly equal to the depth of the pit 5, the surface 6 of the metallic layer 3 opposite the side contacted with the pit 5 is very small compared with the pit 5 even if rectangular recessed and projecting parts are formed, and thus no recessed and projecting parts are formed over the full region of a recording medium. Therefore, even if the protective film 4 is eliminated to make a stamper for a copy disk, the information of the pit 5 formed on one surface of the light-transmissive substrate 1 is not reflected thereby preventing copying.

Title: Servo controlling method for compensating frictional torque
Inventor: YAMAMOTO YOICHI
IPC: H02P29/00
Filed: 1985-05-21
Abstract: PURPOSE:To improve the delay of a servo system due to a frictional torque by setting a value corresponding to the frictional torque as a current command value at the moment that a rotation starting signal and an operating direction inverting signal of a motor are input from a command function generator. CONSTITUTION:A command value generator generates a pulse signal which rises at the movement that a motor rotation start command or a direction inverting command is output. A counter 72 is set to -1 by the signal. A frictional torque converted value is latched to a memory 62 to count up the counter 72, an AND gate 73 is closed, and an output E selects an input C by a multiplexer 71. Accordingly, the value of the frictional torque corresponding to the speed command is output as the output of the memory 62 only at the time of the clock pulse applied to the first input terminal IN1 from the moment when the motor rotation starting signal or the direction inverting pulse signal is output.

Abstract: PURPOSE:To treat waste water containing a lead ion easily, inexpensively and effectively to a dischargeable degree, by adsorbing the lead ions contained in waste water with a cation exchange resin while passing an aqueous nitrate solution through said lead ion adsorbed resin to desorb the lead ion. CONSTITUTION:Waste water 2 containing a lead ion is passed through an ion exchange tower 5 from a waste water tank 1 by a pump 3 and the lead ion is adsorbed with a strong acidic cation exchange resin 4 such as an Na-form one to obtain dischargeable treated water 6. The passing amount of the above mentioned waste water 2 is pref. about LV20m/H on the basis of the strong acidic cation exchanger resin 4 having a resin layer height of about 1,000mm.. When the above mentioned strong acidic cation exchange resin 4 reaches the flow-through point of the lead ion, the passing of water is stopped while an aqueous nitrate solution 7 such as about 5% aqueous sodium nitrate solution is passed through the cation exchange resin to desorb the lead ion to easily re-activate said resin. The desorbed liquid 8 is received in a desorbed liquid tank 9 where alkali is added to make it possible to recover lead as hydroxide by filtering.

IPC: B65D83/00
Filed: 1988-05-09
Abstract: Cream dispensers (1) of a conventional type have a container (2) and a piston (9) with a riser pipe (8). For removal, pressure is exerted on the piston (9) so that the cream emerges through the riser pipe (8). The seal between the piston (9) and a side wall (3) of the container is effected either by precise fitting or by sealing lips. A piston of this type cannot adapt to different container diameters. A cream dispenser is therefore to be provided, in which the container diameter varies with the height. The cream dispenser (1) according to the invention, with a container (2) receiving the cream, has a piston (9) which has on its outer circumferential surface (11) at least one ring (15, 16, 17) of variable outside diameter with an annular gap which is prestressed resiliently in such a way that it rests on the adjacent inside wall of the container. Cream dispensers of this type can be used for toothpaste or the like or for medical creams in the medical sector. <IMAGE>
