Title: Piezoelectric element
Inventor: TSUZAKI MICHIMASA
IPC: H04R17/00
Filed: 1986-04-22
Abstract: PURPOSE:To upgrade the transmission sensitivity and the reception sensitivity when used for a ultrasonic sensor and to drive with a voltage lower than conventional by making the titled element in layered constitution made of thin layers of piezoelectric ceramic interposing an electrode layer. CONSTITUTION:The piezoelectric ceramic aprt of the piezoelectric element 1 is in the three-layer constitution in which the piezoelectric ceramic thin layer 2 and the thin electrode layer 3 are laminated alternately. Of the ultrasonic sensor using the element 1, an external electrode 4 is attached to the side surface of the element 1, thereafter a metal plate 5 which is the transducer is adhered, and the resulting body is fixed on a holder 6. As a result, the distortion generated in the piezoelectric ceramic comes larger and the sound pressure of the ultrasonic wave generated is made higher. Additionally, the impressing voltage can be made lower than the conventional to obtain the same sensitivity as that of a conventional piezoelectric element.

Title: Facsimile equipment
Inventor: KOSHIISHI TAKAYASU
IPC: H04N1/32
Filed: 1988-04-19
Abstract: PURPOSE:To transmit picture information under a desired condition in accordance with a line state by transmitting the picture information in plural communication modes in which the initial data transmitting speed and the data transmitting speed when the data transmitting operation is stopped or data resending number of times are set in different states and processing the data transmission by arbitrarily selecting one mode out of the plural communication modes. CONSTITUTION:In communication mode 1, errorless original transmission is executed in a short period when the line state is good, since the initial value of the data transmitting speed is 9600bps. But the original transmission in communication mode 1 takes time and the communication fee becomes higher when the line state is inferior. On the other hand, since the initial value of the data transmitting speed is set to 4800bps, in communication mode 2, picture information can be transmitted properly at the set speed when the line state is good beyond a certain level. In communication mode 3, the original transmission can be executed efficiently when the line state is equivalent to the state of a normal electric wire line, since the data transmitting operation is similar to the conventional ECM operation. When the communication mode is selected in such way, data transmission can be processed under a desired condition in accordance with the line state.

Filed: 1980-07-11
Abstract: PURPOSE: To prevent an exhaust passage from being clogged with a silicone waste liquid by gelling and precipitating silicone by making the silicone waste liquid alkaline by adding an alkaline substance.  
     CONSTITUTION: The waste liquid of a silicone solution used for the mnufacture of a bulb, such as an instantaneous start type fluorescent lamp, equipped with a wire as a starting conductor on the external surface of a glass tube is collected in a plastic tank. An slight amount of an alkali solution of, for example, caustic potash, ammonia, ethanol amine, etc., is added into the tank by being stirred to increase the pH of the silicone waste liquid until weak alkali. As the stirring operation is continued, silicone is gelled and precipitated in the silicone waste liquid to be se  parated from water completely. Consequently, an exhaust passage is prevented completely from being clogged with waste matter.

IPC: G11B7/26
Filed: 1993-03-30
Abstract: PURPOSE:To obtain a writable optical information recording medium having no fear of peeling between layers by dissolving to remove a light absorption layer on a peripheral edge of a board and so forming a protective layer as to bring the edge of the board into contact with that of the protective layer. CONSTITUTION:A light absorption layer 14 and an enhancement layer 16 are formed on a light transmissive board 12. A reflecting layer 18 is so formed as not to cover an outer peripheral edge of a surface of the board 12 at the layer 14 side. The layers 14, 16 of the edge of the board 12 are dissolved to be removed, and a protective layer 20 is formed on the layer 18 and the edge of the board 12. With this structure, since the edge of the board 12 can be rigidly connected to the edge of the layer 20, a writable optical information recording medium 10 with high reliability and having no fear of peeling between the layers can be manufactured. When the layers 14, 16 at the edge of the board 12 are dissolved to be removed, it is preferable to dissolve to remove it by using resin liquid for forming the layer 20 while rotating the board 12.

Abstract: PURPOSE: To provide an intake air flow control valve driving device which is manufactured at a low cost and simple in structure by employing a negative pressure type actuator. CONSTITUTION: An intake air flow control vale driving device 16 comprises first and second negative pressure chambers 25 and 28. First and second negative pressure chambers 25 and 28 are communicated with an intake branch pipe 10, situated downstream from an intake air flow control valve 17, and the atmosphere through a first negative control valve 30 and a check valve 31, and a second negative pressure control valve 32, respectively. During the starting of an engine, the first and second negative pressure control valves 30 and 32 are controlled to guide an atmospheric pressure in the first and second negative pressure chambers 25 and 28. As a result, the intake air flow control valve 17 is brought into a fully closed state.  When the starting of an engine is completed, by controlling the first negative pressure control valve 30, a negative pressure is guided in the first negative pressure chamber 25, resulting in opening of the intake air flow control valve 17. When, as a negative pressure is guided in the first negative pressure chamber 25, a negative pressure is guided in the second negative pressure chamber 28 by the second negative pressure control valve 32, the opening of the intake air flow control valve 17 is further increased.

Title: Apparatus for manufacture of thin film
Inventor: IMATO SHINJI
IPC: H01L31/04
Filed: 1986-04-24
Abstract: PURPOSE:To prevent a reactive product thin film from forming on an ultraviolet light transmission window without coating oil or the like by applying a bias voltage of a direction for separating ion species that the product becomes solid from the window between a first electrode and a second electrode provided on the window. CONSTITUTION:A power source 11 is so provided as to apply a bias voltage to between a first electrode 4 and a second electrode 2 patterned in a pectinated or latticelike shape on an ultraviolet light transmission window 5. Ion species or active species slightly charged in which reactive product contained in reaction gas becomes solid is separated from the window 5 by a bias voltage applied to between the electrodes 4 and 2. Thus, film forming velocity and critical film thickness are improved, and since oil is not coated on the window 5 like a conventional apparatus, no impurity is mixed in the formed thin film to obtain the film of high quality.
