Title: Unloading of metal hydride from hydrogen storage container containing metal hydride
Inventor: TSUCHIDA YOSHIO
IPC: F17C11/00
Filed: 1986-06-09
Abstract: PURPOSE:To safely unload a finely pulverized metal hydride from a hydrogen- storage container without danger, by removing hydrogen gas from the container, introducing a volatile neutral liquid free from oil and fat and evaporating the liquid to effect the coagulation of the metal hydride. CONSTITUTION:In the unloading of finely pulverized metal hydride from a container 1, a three-way joint 3 is attached to a main valve 2 for feeding and discharging, a valve 4 is opened, a vacuum pump 5 is operated and hydrogen gas in the container 1 is evacuated. The vacuum pump 5 is stopped, the valve 4 is closed, a valve 6 is opened, a pump 7 is operated and a volatile neutral liquid (e.g. trichloroethylene) free from oil and fat is introduced from a tank 8 into the container 1. When the liquid is introduced at an amount to be sufficient to impregnate the fine powder of metal hydride, the pump 7 is stopped and the valve 6 is closed. The fine powder of metal hydride is coagulated by opening the container 1 and rapidly evaporating the volatile liquid. The coagulated powder is crushed to a proper size and taken out of the container through the opening.

Title: Ink jet printer
Inventor: FURUKAWA TATSUYA
IPC: G06K15/10
Filed: 1979-10-13
Abstract: PURPOSE: To enable the size of the printing character to be changed using a low-cost arrangement by a method wherein the excitation frequency, the charging or deflecting voltage and carriage speed are changed over correspondingly to the size of the printing character.  
     CONSTITUTION: When the size of the printing character is instructed by operating a switch or the like, the excitation frequency changes accordingly, whereby the timing of the cutting of the ink line jetted from the ink jet head 5 into ink droplets is changed so that the size of the ink droplets is changed. Since the dot area on the recording paper is proportional to the volume of the ink droplet, the diameter of the dot on the recording paper can be modified arbitrarily by a factor of about two by the change in diameter of the ink droplet. Therefore, when the deflecting voltage is increased according to the size of the ink droplets and the carriage feed speed is simultaneously increased correspondingly thereto, larger characters can be printed.

Title: Arithmetic amplifier
Inventor: MIYAMOTO MASAYUKI

Abstract: PURPOSE: To utilize an amplifier for a high frequency signal by constituting it through the use of more than three-stage odd-number inverting amplifiers and providing a feedback capacitance element between the input and output ends of the inverting amplifiers concerning at least one of the inverting amplifiers so as to make capacitance small. CONSTITUTION: The operational amplifier 11 is constituted that inverters B1, B2 and B3, for example, are serially connected mutually. A serial circuit consisting of the feedback capacitance element CC and a resistance RZ is provided between the input and output ends of the third-step inverter B3 and the input end of the second-step inverter B2 is connected to the power source line 12 of a high level Vdd through the balancing resistances R1 and R2 for adjusting gain. When the capacitance of the capacitor element CC is viewed from the output end of the inverter B2, it is viewed to be multiplied by the amplifying rate of the third-stage inverter B3 by a mirror effect so that a transmission function H(s) has a first pole SP1 at a prescribed position.  Therefore, when the inverter B2 has the same constitution as that of the inverter B3, the capacitance of the element CC is obtained from the first pole and the pole SP1 of the operational amplifier 1.

Filed: 1990-05-22
Abstract: PURPOSE:To immediately synchronize with an input signal, when the input signal comes to '1' by applying a voltage held in a DC holding circuit to a voltage controlled oscillation circuit, when the input signal comes to '0'. CONSTITUTION:A phase difference signal detected by a phase detecting circuit 2 for comparing phases of an input signal applied to an input terminal 1 and an output of a voltage controlled oscillation circuit 4 is inputted to a loop filter 3, its output is extracted as to its DC portion by a DC extracting circuit 6, and the DC portion is held in a DC holding circuit 7.

Abstract: PURPOSE:To permit to take out hot-water in a hot-water reserving tank as much as possible without mixing it with feed water under preventing the air mixing-in operation of a pump by a method wherein a hot-water outlet pipe is taken out of the lower part of the hot-water reserving tank and a water level detector is provided in the hot-water reserving tank to control the opening and closing of a feed water valve as well as the forced stopping of a heat collecting pump and a hot-water supplying pump. CONSTITUTION:The water level detector 31 does not open the feed water valve 30 until the water level of the hot-water reserving tank 16 descends to a height slightly higher than (ha) from a hot-water outlet port 22, therefore, the substantially whole amount of the hot-water in the hot-water reserving tank 16 may be taken out without mixing it with the feed water in case the large amount of hot-water is supplied to a bathtub 23. When the water level is lowered to the height (ha), the feed water valve 30 is opened and water feeding is initiated. At this time, the water level detector 31 stops forcibly the heat collecting pump 19 and the hot-water supplying pump 25 regardless of a temperature difference controller 34 or a pressure switch 27 to prevent the air mixing-in operation of these pumps.

Filed: 1981-08-24
Abstract: PURPOSE:To form an optical plain surface circuit having a branching and junction part having less scattering loss, by making the refractive index distribution in a sectional direction of an optical waveguide into a graded distribution by an ion exchange method. CONSTITUTION:A part corresponding to an area forming an optical waveguide on a substrate 1 is exchanged by the ion contributing to enlarge a refractive index to form a high refractive index layer. Then, the unnecessary part of the high refractive index layer is removed by etching to form a prescribed optical waveguide pattern 2. Afterwards, the surface of the pattern 2 is exchange by the ion contributing to make a refractive index small and the distribution in which the refractive index in a section of the waveguide 2 is high in the center and is decreased as it goes to the circumference is given. Thus, by making the refractive index distribution in a sectional direction of the optical waveguide into a graded distribution, an optical plain surface circuit having a branch and juction part having less scattering loss is formed.

Abstract: PURPOSE:To realize excellent pattern and tone stability and the reproducibility of a fine line without generating register shift by changing the thickness of a gripper plate on and after the first and second times when a photosenstive sheet for an etching plate is transferred in case of the combination of a plate formed by mechanical carving and a plate formed by etching. CONSTITUTION:For example, when four pages in a plate circumferencial direction and four pages in an axial direction are laid out to form a publishing gravure plate, transfer is performed to the surface of a cylinder 2 in a state divided into two times at every two sheets in the circumferencial direction in a four-page unit. When a plate formed by mechanical carving and a plate formed by etching are combined, since the plate formed by mechanical carving is electrically divided into two and 180 deg. is accurately obtained, there is no problem. However, in case of a photosensitive sheet for an etching plate during an etching process having a gripper plate 5, a thickness control film 4 is provided at the time of the first transfer so as not to eliminate difference between the first and second times at the time of transfer to accurately issue 180 deg. and the positional relation to the plate formed by mechanical carving is matched so as to match register at the time of printing.
