Filed: 1988-07-20
Abstract: PURPOSE:To obtain an ink composition which can give an image of a high density and a high water resistance and has a marked electroviscous effect by dispersing or suspending dielectrically polarizable polymer particles dyed with a reactive dye in an insulating liquid. CONSTITUTION:This ink composition is obtained by dispersing or suspending dielectrically polarizable polymer particles (e.g., cellolose powder) which can be dyed with a reactive dye (a colored compound having a functional group through which a covalent bond can be formed between the dyed piece and the dye by a chemical reaction with the dyed piece, for example, C.I. Reactive Yellow 1-71 or C.I. Reactive Red 1-115) in an insulating liquid of an electrical resistance >=10<5>OMEGAcm (e.g., bromonaphthalane).

Title: Magnetic disc device
Inventor: OGAWA SATORU
IPC: G11B19/04
Filed: 1982-10-14
Abstract: PURPOSE:To eliminate the need of care for whether or not a cassette is mis- loaded, by providing a mis-loading detecting means of a magnetic disc cassette to a device side so as to eject automatically the cassette when the mis-loading is detected. CONSTITUTION:When a magnetic disc cassette 5 is loaded in the correct direction, a timer signal for mis-loading detection rises to a high level in synchronizing with the rise of a magnetic disc clamp signal and goes to a low level after a prescribed time. On the other hand, if a ready signal is not at high level when the mis-loading detecting timer signal falls down to a low level, the magnetic disc device is discriminated that a disc cassette 5 is mis-loaded. In this case, a drive signal of a motor goes to high level and a forward/reverse signal of the motor is confirmed to the low level. As a result, the mis-loaded magnetic disc cassette 5 is ejected automatically from a loading port 4 to the outside of the device with a drive roll 7.

An interlayer insulating film 5 is formed on the polycide interconnection. In this case, since the sidewall 7 is formed in a tapered state, a cavity to be formed between an interlayer insulating films is not formed.

Inventor: GOI HIROSHI
IPC: E03D5/10
Filed: 1993-07-20
Abstract: PURPOSE:To save water consumption to a great extent by a method wherein an imitation sound is produced when a user sits on a toilet seat, and water is started to flow inside a toilet bowl for a specified period of time for washing while the imitation sound is cut off when the user gets up from the toilet seat. CONSTITUTION:When a user sits on a toilet seat, a controller 10 receives a turning-on signal from a sitting sensor 8 and outputs a driving signal to an imitation sound producing circuit 11, and thereby an imitation sound is given out of a speaker 9. When the user gets up on finishing the use of a toilet, the sitting sensor 8 is turned off, then the controller 10 stops the output of the driving signal to the imitation sound producing circuit 11 and drives an actuator 4 to open a water supply valve 3 for washing the inside of a toilet bowl 1. In the case where the user pushes an operating button 7 on sitting on the toilet seat, the imitation sound is not produced. Then water is started to flow inside the toilet bowl 1 for a specified period of time when the user pushes the operating button 7 again on finishing the use of the toilet. Therefore, water-saving can be made certainly.

Title: Ultrasonic probe for detecting surface indentation
Inventor: YAMAMOTO HIROSHI
IPC: G01N29/24
Filed: 1992-07-07
Abstract: PURPOSE:To enable detection of minute indentation by using an ultrasonic wave, by making a transducer be held between upper and lower electrodes provided in the shape of rings at positions of incident angles on a concave part of an acoustic lens at which angles of total reflection for a part of surface flaw detection are formed. CONSTITUTION:The surface 1A of an acoustic lens 1 is made flat, while the bottom 1B thereof is made concave. At a position of incidence at which an angle of total reflection on the bottom 1B is formed, a transducer (piezoelectric element) 2 is provided in the shape of a ring. On the upper and lower sides of this transducer 2, an upper electrode 3A and a lower electrode 3B are provided for excitation of an ultrasonic wave and reception thereof, and indentation of a surface is measured precisely only by using the ultrasonic wave reflected totally. In respect to a part P of surface flaw detection, for instance, the ultrasonic wave emitted from a transducer 2A is reflected totally on the part P and a transducer 2B receives this total reflection. The ultrasonic wave transmitted from the transducer 2B, to the contrary, is received by the transducer 2A. When the surface of a sample 4 is smooth, the wave is reflected totally and, therefore, a reception strength becomes large. When it has indentation, the reflected wave is disturbed and the reception strength becomes small. Since any of a longitudinal wave, a transverse wave and a Rayleigh surface wave are not generated on the occasion, interference thereof with the totally reflected wave is eliminated and only the totally reflected wave from the part P can be detected.
