Title: Sequentially occurring events indicating device
Inventor: IWASAKI SHINICHI
IPC: G09G5/00
Filed: 1988-06-20
Abstract: PURPOSE:To intuitively analyze an event group by representing an event by a rectangle, and making a side of it be the appearing time length of the event, and determining the length of the other side so that sequentiality can be represented favorably. CONSTITUTION:An event data inputting means 10 delivers inputted data, and an event designating means 20 delivers the identification symbol of an indication started event, and a reference time coordinate axis holding means 30 delivers a scale to convert a reference coordinate and the length of time into distances on coordinates respectively to a processor 40. The processor 40 generates pattern information to determine the rectangle whose one side is made to be the length equivalent to the appearing time of the event and in addition, whose other side is made to be the length equivalent to the number of paths to the event which can be arrived as considering this event to be a starting point and has no subsequent event, and positions the rectangle equivalent to this pattern information upon a two-dimensional display screen provided on a display means 50. Thus, the analog display of the event can be achieved instead of the digital indication of the appearing time which is the defect of an arrow diagram, and in addition, the sequentiality can be recognized intuitively.

Patent JP-S6130805-A (JP)
Title: Current mirror circuit
Inventor: IWASA TAKASHI
IPC: H03F3/34
Filed: 1984-07-24
Abstract: PURPOSE:To obtain an output current nearly equal to an input current even if an output voltage is higher by adopting the constitution that a collector-emitter voltage of an input transistor (TR) and that of an output TR are of equal level. CONSTITUTION:A TR7 is to suppress a VCE of an output TR4 by one diode voltage, the base is connected to a connecting point between a collector of the TR3 and a base of a TR5, the emitter is connected to a collector of the TR4 and the collector is used as an output. Then the TR7 acts like the active region. In inputting a current I1 by a constant current 2, since the collector-emitter voltage of the TR3 is the sum between the base-emitter voltage of the TR3 and the base-emitter voltage of the TR5, the voltage is equivalent to 2 times of diode voltage. The collector-emitter voltage of the TR4 is equivalent to one diode voltage.

CONSTITUTION:A speaker grill 12 is a member covering the front surface to protect a speaker unit 11, is mounted on the speaker unit 11, a door or a rear tray board, is normally composed of resin and has a comparative thickness. The sectional shape of a grill member 14 composing the front surface of the speaker grill 12 is a rhombus in which the both surfaces become diagonal and the front face is made a grid-shaped structure. Therefore, each of sound passing through holes 13 which are the hole parts of the grids of the grill member 14 and pass the sound outputted from the speaker unit 11 becomes wider as the holes are closer to the both surfaces of the speaker grill 12 and becomes narrower as the holes are closer to a center.

Title: Rotary compressor
Inventor: NAKAJIMA NOBUFUMI
IPC: F04C18/344
Filed: 1985-07-12
Abstract: PURPOSE:To decrease mechanical loss between the point end of a vane and the internal surface of a cam ring, by forming a back pressure chamber in the base end part of the vane to selectively communicate with high and low pressure regions bordering a predetermined rotary speed thus holding a surface pressure in the point end of the vane to a fixed value. CONSTITUTION:A housing groove 27, communicating with a back pressure chamber formed in the base end part of a vane, is formed in the side surface of a rotor 11, and a ball 27 is contained in said housing groove 27. A plate 32, being arranged in a cut part 30 of a front side block 9 facing to the housing groove 27, is adapted to the ball 28 by urging force of a spring 31. If a speed of the rotor 11 increases, the ball 28, pressing by centrifugal force the plate 32 to a side of the front side block 9 against the urging force of the spring 31, causes the plate 32 to block an opening part 34b of a high pressure communication path 34. In this way, a pressure in the back pressure chamber 18, gradually decreasing by a leak, causes a surface pressure in the point end of a vane 17 to decrease.

Moreover, an electron beam generation source 14, which generates and radiates electron beams 14a on the surface of the material piece 11 selectively cutback by sputtering etching, is installed near the mount 12. A charge measuring means 15 is installed near the mount 12, which measures simultaneously the charge applied to the material piece 11a from the electron beams 14a at two positions separated. The amount of current or voltage ratio measured respectively by a probe and contact 15a is compared with a standard value by a resistance measuring means 16 so as to measure and compute resistance changes in the depth direction on the surface of the material piece 11. It is, therefore, possible to measure changes in receptivity by the radiation to fine regions.

Title: Stainproofing agent for resin and stainproof resin containing the same
Inventor: SOGA SANEMORI
IPC: C08L101/00
Filed: 1998-06-03
Abstract: PROBLEM TO BE SOLVED: To provide a stainproofing agent which can provide a resin excellent in resistance to greasy stains, and its durability against rubbing, abrasion, and steam. SOLUTION: Antioxidant molecules 3 having rubbing and abrasion resistance and oil repellency are dispersed in a general purpose resin 2. Near the surface of the resin the moieties of antioxidant molecules are present inside the resin because of their good compatibility with the resin, whereas the oil-repellent moieties of the molecules are oriented to establish a state in which they are exposed to the surface air layer because of their incompatibility with the resin. The oil-repellent antioxidant molecules 4 are oriented on the surface of the resin until a closely packed state is reached, whereas the extra oil-repellent antioxidant molecules are present in a state in which they are dissolved in the resin.  Even if the oil-repellent antioxidant molecules 4 are partly removed from the surface of the resin by rubbing or abrasion, the oil-repellent antioxidant molecules 4 dissolved in the resin are diffused into the surface of the resin to replenish the defects to thereby keep the surface oil-repellent.

Abstract: PURPOSE:To attain ease of beam position adjustment with less components by separating optical path of a collimator lens collimating radiated light from plural semiconductor lasers from plural beams making incident to a recording medium via a condenser lens and reflecting from the recording medium. CONSTITUTION:Irradiated lights 20a, 20b from semiconductor lasers 21a, 21b are collimated by a common collimater lens 22 and made incident to a polarized beam splitter 23. The light is not polarized by the polarized beam splitter 23 but straight-forwarded, the P polarized light is converted into circularly polarized light through a lambda/4 plate 24 and condensed on a recording medium through the condenser lens 26 fitted to an actuator 25. The interval in the (y) direction of two beams on the recording medium 27 is decided by magnification of the converged optical system and is 1-1/2 of the array interval of the semiconductor laser normally. Since the converged position shift between two beams in the focus direction is shared in common to the collimeter lens and the converged lens, the shift is not almost caused and a problem in a conventional constitution collimating plural beam with separte collimator lens is eliminated.

Then, a mesa etching is applied by means of a predetermined pattern, and thereafter, an aluminum electrode 6 is formed. Moreover, if a passivation film of, e.g., silicon dioxide (SiO2) is formed on a mesa groove 7 by a chemical vapor growth of 400 deg.C, then it is possible to obtain a varactor element utilizing oxygen donors.
