Title: Method for preventing corrosion of hydrogen separator for sodium chroride electrolytic cell
Inventor: TAKAMURA MASATAKA
IPC: C25B15/00
Filed: 1984-08-20
Abstract: PURPOSE:To prevent the corrosion of a hydrogen separator for a brine electrolytic cell provided with an ion exchange membrane by attaching a dropper for dropping an NaOH soln. to the hydrogen separator so as to break an electric circuit in the separator. CONSTITUTION:When an aqueous NaCl soln. is electrolyzed in an electrolytic cell 1 provided with an ion exchange membrane, a mixture of an aqueous NaOH soln. with gaseous H2 is produced on a cathode 3 and sent to an H2 separator 5, where the geseous H2 is separated from the NaOH soln. 8 and sent to an H2 storage tank through a pipe 6. The NaOH soln. 8 is sent to a dropper 11 through a pipe 7 before sending to a concentrator. In the dripper 11, the NaOH soln. 8 drops 13 through a deispersion plate 12 made of an electric insulator. By this dropping, an electric circuit in the H2 separator 5 is broken, so the electric corrosion of the separator 5 can be prevented.

Title: Semiconductor amplifier
Inventor: MATSUNAGA TAKAHARU
IPC: H03F3/193
Filed: 1998-06-18
Abstract: PROBLEM TO BE SOLVED: To reduce power consumption by miniaturizing a distortion compensation circuit. SOLUTION: A characteristic improvement circuit 10 composed of a passive circuit comprising a capacitor 5, a resistor 6 and an inductor 7, and of a common source drain FET 8 connected to the passive circuit is connected between input matching circuits 2 and 3 for an amplification nonlinear amplifier element (FET1). In the characteristic improvement circuit 10, a gate capacitance of the FET 8 increases as an input level increases, a passing gain increases and a passing phase is decreased. A phase characteristic and a distortion characteristic of the amplifier at an output level are improved by compensating the characteristic of the FET1 according to the characteristic above. Since the characteristic improvement circuit 10 is configured on a same printed circuit board for the input matching circuits 2 and 3, the semiconductor amplifier is made small.  Since the capacitor 5 blocks a DC current, the power consumption is not increased.

Title: Original retaining device
Inventor: KOBAYASHI TATSUO
IPC: G03G15/04
Filed: 1984-08-20
Abstract: PURPOSE:To hold well thick originals as well as thin originals by connecting one end of a pair of links freely vertically turnably to both end faces of an original retaining cover and connecting the other end of these links freely vertically turnably to the fixed side. CONSTITUTION:When a thin original A is copied, a receiving piece 10 is attracted to a magnet 11 to fix a link 6, and an original retaining cover 5 is vertically turned around a pin 7. At this time, since the link 6 is held and the original retaining cover 5 is not turned together with the link 6, the operation is easy. When a thick original B is copied, the receiving piece 10 and the magnet are separated from each other when the original retaining cover 5 is pressed to the thick original B, and the link 6 is turned upward around a pin 9, and the original B is retained surely.

Title: Portable information terminal
Inventor: SHINODA KAZUHISA
IPC: H04W4/20
Filed: 1997-06-27
Abstract: PROBLEM TO BE SOLVED: To provide a portable information terminal, which enables precise setting, by determining a suitable response method while linking a personal information managing part and an automatic response control part. SOLUTION: When there is an incoming call to a wireless telephone, a radio part 2 acquires the telephone number information of a call origination source from a wireless telephone base station through a control channel, and that number is reported from the radio part 2 through a voice/data switch part 6 and a MODEM part 5 to a main control part 1. The main control part 1 inquires the method of a response to the incoming call to an automatic response control part 12.  This automatic response control part 12 discriminates the call origination source by effectively utilizing starting ID (telephone number or address) information sent from a communication network and comparing it with a number stored on an electronic telephone directory at a personal information managing part 11 and determines the response method of call incoming according to attribute information added to the personal information of that call origination source. Namely, it is judged whether or not the retrieved result of the incoming call and electronic mail from a FAX is to be positively reported.

Title: Brake operating method
Inventor: ISHII AKIRA
IPC: B60T8/26
Filed: 1984-08-18
Abstract: PURPOSE:To reduce a degree of fluctuations in a car body at both forward and backward movements, by controlling brake feeding pressure to the rear-wheel side to be reduced in time of a car forward movement and also reduce the pressure to the front-wheel side in time of a car backward movement. CONSTITUTION:In time of a car forward movement, if braking takes place, pressure in a master cylinder is fed to each of front and rear wheel cylinders via pressure reducing valves 26, 31 and 71, 74. In time of it forward movement, a valve gear 76 is opened and since the master cylinder pressure is also fed to a control chamber 27, a main piston 20 is not moved. Therefore, the pressure reducing valve at the front-wheel side is no longer operated and thereby the rear- wheel side alone is controlled to reduce its pressure. At braking in time of a car backward movement, a coil 37 is excited and the valve gear 76 is closed. With this constitution, the master cylinder pressure is not transmitted to the control chamber 27 so that the main piston 20 is made movable, thus pressure at the front-wheel side is controlled for pressure reduction. And, fluid pressure in a small diametral hole 60 is zero whereby the rear-wheel side comes high in its reduction starting pressure so that no reduction control takes place usually.

CONSTITUTION:A grain-oriented silicon steel strip which has a composition consisting of, by weight, <=8% Si and the balance essentially Fe and a {110}<001>-oriented texture and also has crystalline grains having average grain size of >=20mm and >=40mm in a rolling direction and in a direction (width direction of steel strip) perpendicular to this rolling direction, respectively, and in which magnetic flux density B8 satisfies B8/BS>0.9 (where BS means saturation magnetic flux density in the component system) is cold-rolled at least once at 60-80% reduction of area to <=150mum final sheet thickness. Subsequently, this cold rolled sheet is held at 400-700 deg.C for the prescribed time, if necessary, and is subjected to primary recrystallization annealing. Then, a region having low magnetic permeability as compared with ferrite (steel sheet) is periodically formed in the vicinity of the steel sheet surface.

CONSTITUTION:An engine utilizing alcohol modified gas, of this invention, comprises a low-load gas pressure setting circuit 32 which is furnished with the output signal of a gas flow setting circuit 31 and produces an output signal for controlling the pressure of the modified gas at about 1.5 ata when the engine is operated by the modified gas. The output signal of the circuit 32 is applied to one terminal of a comparator 33 while the output signal of a gas pressure sensor 15 is applied to the other terminal of the comparator 33 via a gain control circuit 34. The comparator 33 makes comparison between the output signal of the gas pressure sensor 15 and a reference input value corresponding to the gas pressure, furnished from the gas pressure setting circuit 32. Here, in case that the former is lower than the latter, a solenoid valve 5 disposed at a portion of an alcohol passage is opened, but it is kept closed in other cases.
