Title: Developer for pressure sensitive recording paper
Inventor: TSURUMI YOSHIHIRO
IPC: B41M5/155
Filed: 1979-07-25
Abstract: PURPOSE:To improve the developing ability by a method wherein aromatic carboxylic acid having hydroxyl radical is subjected to condensation with xylene resin and compounded as the developer. CONSTITUTION:Aromatic carboxylic acid having hydroxyl radical like salicylic acid, p-hydroxybenzoic acid, etc. and their copolymer are subjected to condensation with xylene resin and phenol as the third component or phenol-aldehyde copolymer at 100-110 deg.C for 1-5hr under a catalyst like hydrochloric acid or sulfuric acid. Aromatic carboxylic acid and phenol are applied at 0.5-7 parts each to xylene resin 1. A developer thus obtained is dissolved in an organic solvent, polyhydric metal compound, inorganic pigment, binder, etc. are added thereto, and thus a pressure sensitive recording paper superior in developing performance is obtainable through impregnating a support therewith or applying it thereto, or employing it as a microcapsule.

Title: Photocatalytic cloth
Inventor: TOUGEDA HIROSHI
IPC: B01J31/06
Filed: 1998-04-07
Abstract: PROBLEM TO BE SOLVED: To obtain a photocatalytic cloth whose shape can be optionally changed and hold the shape as it is and which is highly durable and heat-resistant and further effectively decomposes and cleans a smell and an injurious material by coating a fiber consisting of a metallic wire and a glass yarn with a resin containing titanium oxide. SOLUTION: The cloth 1 is of such a constitution that a glass yarn 2 and a copper wire 3 are interwoven, and a treatment liquid is prepared by dispersing an anatase-type titanium oxide 4 powder in a tetrafluoroethylene resin emulsion. Next, the cloth 1 is soaked in the treatment liquid, then is dried and baked. Further, this soaking, drying and baking processes are repeated to obtain a cloth on which a fluororesin-coated layer 5 containing the titanium oxide 4 powder is formed, that is, the photocatalytic cloth 6. The photocatalytic cloth 6, interwoven with the copper wire 3, can be bent to a specified shape and keep it as it is. The titanium oxide 4 of the fluororesin-coated layer 5 generates electrons and positive holes by receiving a light such as of a fluorescent lamp or a solar ray to cause an oxidation and reduction action to take place.  Thus, it is possible to decompose and clean a smell, an injurious material, a pollutant or the like and ensure the high durability and superb heat resistance of the photocatalytic cloth and keep its changed shape as it is.

Title: Triac
Inventor: NAKATANI YOSHIHARU
IPC: H01L31/111
Filed: 1984-05-11
Abstract: PURPOSE:To obtain a Triac, voltage thereof hardly drops under the state of turn-ON and which has large resistance of a change with time on turn-OFF, by joining P-N-P-N-P or N-P-N-P-N five semiconductor layers in succesion, fitting electrode terminals to the semiconductor layers at both ends and generating photocurrents in P-N junctions, to which reverse bias voltage is being applied, by the projection of beams. CONSTITUTION:P-N-P-N-P five layers are formed in a bilaterally symmetrical manner. That is, two N type regions 2 and 3 are shaped in a P<-> type Si substrate 1, and P<+> type regions 4 and 5 are each diffused and formed in the regions 2 and 3. Electrode terminals (a) and (b) are connected to the regions 4 and 5 and reverse bias voltage is applied, and P-N junctions generated among each layer are irradiated with beams of generate photocurrents. Consequently, an equivalent circuit for the device can be regarded as the coupling of three transistors Tr1, Tr2, Tr3, and the current amplification factor of Tr1 is made smaller than that of Tr2. Accordingly, discharge currents are reduced, use in high frequency is also enabled, and characteristics on a turn are improved.

Title: Screen
Inventor: KAWAMURA HIROSHI
IPC: G03B21/62
Filed: 1981-06-18
Abstract: PURPOSE:To obtain a screen which hardly causes a sudden change in color, by correcting an uneven shape for diffused reflection of light. CONSTITUTION:To provide incident light with optical directivity by diffused reflection, a screen for a projection type television has fine unevenness. When the projection shape is corrected to obtain a prescribed elliptic shape having a long axis (a) and a short axis (b), the intensity P and direction phi of a reflected wave satisfy equationI, and the reflection coefficient ratio R for determining the directivity of diffused reflection approximates to an ideal value which satisfies equations II according to selected coefficients K and (n). In the figure, an incident beam is at an angle theta, and consequently a shift in position on the screen is caused to vary the angle of incidence, so that even when each color cathode-ray tube has a different limit angle of incidence, the screen easily changes in color suddenly like an arc-shaped uneven shape.

Filed: 1995-04-20
Abstract: PURPOSE: To eliminate the need of a complicated manufacturing process so as to reduce the manufacturing cost and size of a power semiconductor device by integrally forming an insulating circuit board and frame-like case of the same resin and forming a circuit pattern of a metallic plate on the circuit board. CONSTITUTION: A frame-like case 5 which becomes the side wall of a liquid sealing resin housing section and insulating circuit board 6 which becomes the bottom of the housing section are integrally molded of the same resin.

An external output terminal 4 integrally formed with the circuit pattern 2 is bent at an angle of about 90 deg. against the pattern 2 and led out of the case 5 after passing through the case 5. The patterns 1 and 2 and terminal 4 are made of brass, etc., plated with tin, etc. Therefore, the manufacturing cost of a power semiconductor device can be reduced, because no complicated process is required at the time of joining the case 6 to the board 6.

Title: Image forming device
Inventor: CHIBA NORIYOSHI
IPC: G03G15/00
Filed: 1988-04-18
Abstract: PURPOSE:To make the title device small in size and to save energy by utilizing the pour of charges for a means for forming a latent image. CONSTITUTION:In case of exposing on an image forming member 7, the resistance of an exposed photoconductive part 2 becomes lower and the electrostatic capacity of the image forming member 7 becomes larger than an unexposed part. When conductive toner 4 supported by a conductive sleeve 5 comes into contact with the image forming member 7 in a state where a specified voltage is impressed between the conductive part 3 of the image forming member 7 and the conductive sleeve 5, the charges corresponding to the electrostatic capacity of the image forming member 7 are poured in the conductive toner 4. Since the amounts of charges poured in the conductive toner 4 which comes into contact with an exposed part and the unexposed part are different, electrostatic attraction forces become different. If the constraining force of the conductive toner 4 to the conductive sleeve 5, for example, a magnetic force or an electrostatic force, is adjusted in such a case, only the toner 4 which comes into contact with the exposed part can be selectively developed. Thus, the device can be made smaller without ruining image quality and low power consumption can be accomplished.

Title: Oscillation circuit
Inventor: HIROSE TAKUMI
IPC: H03K17/78
Filed: 1986-04-25
Abstract: PURPOSE:To enable an oscillation cycle to be switched in two stages through the use of an oscillation capacitor, by providing a working circuit that detects the terminal voltage of the oscillation capacitor, and performs a charging/ discharging operation. CONSTITUTION:Since a state control transistor 7 is turned off when a control signal S8 is at a low level, a current 2i between the emitter and the collector of a transistor 5 is divided as a current (i) between each emitter and collector of transistors 10 and 11. When the control signal S8 is at a high level 'H', the current 2i running between the emitter and the collector of the transistor 5 is permitted to run between the collector and the emitter of the transistor 11, because the state control transistor 7 is turned on. In this way, it is possible to switch the oscillation output of an oscillation circuit A to oscillation pulses having different oscillation cycles in two stages, only by using one oscillation capacitor.
