Title: Ultrasonic probe and its manufacture
Inventor: NAKAO NARITAKA
IPC: G01N29/04
Filed: 1987-12-16
Abstract: PURPOSE:To prevent cross coupling and to obtain blood flow data having a good S/N, by making the first and second piezoelectric element groups equal in thickness and constituting rear bodies of material qualities different in acous tic impedance while constituting the front matching layers of the same material with the same thickness. CONSTITUTION:The piezoelectric plates 10 of piezoelectric element groups 1a, 1b are equal in thickness and the matching layers 13 thereof are also equal in thickness. The rear body 11 of the first piezoelectric element group 1a is made small in acoustic impedance to enhance its transmission efficiency and the rear body 12 of the second piezoelectric element group 1b is made large in acoustic impedance. Be providing difference between the acoustic impedances of the adjacent rear bodies 11, 12, cross coupling or cross talk is prevented. Since an ultrasonic wave is transmitted in a pulsating manner to perform elec tron scanning in order to obtain tomographic data, acoustic impedance is made large in order to widen a transmitting ultrasonic wave band and to shorten a pulse time.

IPC: G06F1/30
Filed: 1999-11-09
Abstract: PROBLEM TO BE SOLVED: To surely re-start a game after a recovery from power interruption by judging power interruption in an early stage and preserving desired information. SOLUTION: The game machine such as pachinko machine is provided with an AC power source 2 for supplying a power source to at least a game control part 6b, the game control part 6b for preserving desired information when a power interruption signal which indicates that power is interrupted is received and re-starting the game after the recovery from power interruption based on preserved desired information and a power interruption detecting part 4 for outputting the power interruption signal when power interruption is discriminated based on the waveform of the AC power source 2. The power interruption detecting part 4 outputs the power interruption signal when power interruption is discriminated based in the waveform of the power source 2.  The game control part 6b which receives the interruption signal preserves desired information in a preserving part 6a and re-starts the game after the recovery from power interruption based on preserved desired information. The interruption signal is outputted in an early stage since the detecting part 4 discriminates whether power is interrupted or not based on the waveform of the AC power source 2 so that the game control part 6b surely re-starts the game after the recovery from power interruption.

Title: Optical distance measuring apparatus
Inventor: SAITO TETSUYA
IPC: G01C3/06
Filed: 1990-11-24
Abstract: PURPOSE:To automate gain adjustment and to make it possible to perform accurate measurement by adjusting the amplification factor in response to the amount of received light obtained by adding the threshold value that is proportional to the amount of light emission and the output of a position detecting element. CONSTITUTION:Both output currents of a position detecting element 2 are converted into voltages 5, and output signals V1 and V2 are obtained. The signals V1 and V2 are added 15. The signal undergoes pulse modulation, and the result is inputted into a comparator circuit 16. At this time, the output of the adder 15 is proportional to the total sum of the amounts of the received light of the element 2. Meanwhile, a voltage signal Vm obtained by converting the photocurrent value which is detected with an emitted-light-amount detecting element 14 undergoes pulse modulation and the result is inputted into the circuit 16. The signal is converted into a signal Vm' which is proportional to the light emitting amount of a light emitting element 1. The signal is compared with the output of the circuit 15. The signal is inputted into a variable amplification-factor amplifier 6. The signal is compared with the threshold value which is proportional to the light emitting amount of the element 1. When the output of the circuit 15 corresponding to the light receiving amount is small, the amplification factor is made high. Conversely, when the output of the circuit 15 is large in with the threshold voltage, the amplification factor is made low. When the amplification factor is automatically adjusted by the operation of an automatic gain adjusting part 17 in this way, the light receiving amount is kept approximately constant, and accurate measurement can be performed.

Filed: 1995-12-08
Abstract: PROBLEM TO BE SOLVED: To provide a fine pattern on a shifter contradictory portion of a phase shift mask without changing a mask pattern. SOLUTION: A shifter is automatically arranged and a contradictory portion is extracted. Electron beam radiation data is formed by using a pattern corresponding to the contradictory portion. A pattern is formed by radiating only the electron beam on the contradictory portion. The same sensitive materials are exposed to light and superimposed with each other. An electron beam lithography process is then directly conducted to the superimposed sensitive materials to thereby generate a pattern. The order of exposure and electron beam lithography processes can be reversed. If continuously conducting exposure and electron beam lithography processes, following processes such as a development process can be conducted in common.

Title: Material for copper alloy melting furnace and its sintering method
Inventor: SHIMAMURA NOBUO
IPC: C04B35/14
Filed: 1989-12-09
Abstract: PURPOSE:To obtain the material low in heat conductivity and to prevent the diffusion of a metal having low m.p. and b.p. through the material by forming the material from a refractory material consisting essentially of electrofused silica and natural silica and incorporating a glass layer formed by the fusing of the electrofused silica into the material. CONSTITUTION:Electrofused silica and natural silica are mixed, and boric acid, for example, is added as a binder to obtain a refractory material. The material is dry-formed into a vessel, and the formed product is sintered. In this case, the product is rapidly heated to 1400-1600 deg.C in a short time, held at the temp. for 30min, and then quenched to obtain a sintered furnace material A. By this sintering method, the electrofused silica is fused and then cooled to form an airtight glass layer a on the inner surface of the material A. Consequently, even if the copper alloy contg. a metal having low m.p. and b.p. such as zinc is melted, the diffusion of the vaporized material through the material A is prevented, and the heat conductivity is low because the material consists essentially of silica.
