Title: Probe and ultrasonic wave flaw detecting method
Inventor: UCHIDA KUNIHARU
IPC: G01N29/04
Filed: 1982-12-28
Abstract: PURPOSE:To make it possible to detect the defect in the vicinity of a surface layer part of a body to be checked highly efficiently, by the constitution wherein one vibrator is made to be a wave transmitting vibrator to which a refraction angle setting body is attached, and a vibrator group other than the above-mentioned vibrator is used as a wave receiving vibrator group. CONSTITUTION:An ultrasonic wave beam is transmitted from a wave transmitting vibrator 6 with a wedge shoe 5 to a body to be checked 2 at a refraction angle theta. The number of excitations and combination of wave receiving vibrators 71-7n are determined by electronic scanning, so that the ultrasonic wave beams, which are received in correspondence with the depths of flaw, are converged in correspondence with the depth of the flaw and the direction of the flaw. The received signals are delayed and added based on the received ultrasonic wave beams, and the flaw is detected. In this method, the attenuation of the reflected wave or diffracted wave of the ultrasonic wave beam can be corrected in the deep region from the surface of the body to be checked 2. The defect can be detected highly sensitively. The shape and the size of the defect can be estimated highly accurately.

Filed: 1987-09-19
Abstract: PURPOSE:To discriminate the not-ready state of a line terminating device or that of a terminal equipment by transmitting the fact that the terminal equipment is set at the not-ready state by setting an R line at 1 and turning OFF an I line. CONSTITUTION:A host computer 6 outputs t=1 to a T line when a state is set at a ready state. The R line, when the line terminating devices 7 and 8 and the line being normal, goes to 1, that is, it goes to r=1, and is added on the terminal equipment 9 from the line terminating device 8. The titled device is constituted in such a way that connection is performed by dot line Y in the terminal equipment 9 when current on the terminal equipment 9 is cut off. Therefore, output is issued to the T line after it goes to r=1 and t=1, and it goes to r=1 via the line terminating device 8, a digital line, and the line terminating device 7, then it is added on the host computer. Also, the C line of the terminal equipment 9 goes to non-potential (since no power source is applied), and the line terminating device 8 detects c=OFF, and similarly it is transmitted to the host computer by setting i=OFF via the digital line and furthermore, the line terminating device 7.

Title: Preparation of denitrification catalyst
Inventor: KONISHI KUNIHIKO
IPC: B01J37/02
Filed: 1988-09-19
Abstract: PURPOSE:To finely disperse catalyst particles for improving the catalytic activity by previously subjecting the catalyst material containing titanium, vanadium, etc., to heat treatment to reduce SO4 content and adding surface-active agent thereto for mixing therewith by a wet method and the subsequent formation into a catalyst. CONSTITUTION:In a denitrification catalyst for use for removal of nitrogen oxides, the catalyst material containing titanium, vanadium and molybdenum or tungsten is previously subjected to heat treatment, so that SO4 content will not exceed 4wt.%, and then admixed with surface-active agent and an inorganic fibrous substance by a wet method and formed into a catalyst. Such addition of the surface-active agent with the SO4 content held below a fixed value will not create the aggregation of titanium oxide particles contained in the material and permits the catalyst formation even in a larger water content. Therefore, the finely dispersed catalyst particles lead to the formation of a highly active denitrification catalyst.

Title: Image pickup signal processing circuit
Inventor: TANJI ICHIRO
IPC: H04N5/367
Filed: 1990-09-06
Abstract: PURPOSE:To preclude the possibility of picture quality deterioration due to a correction error attended with sensitivity changeover by synchronizing the selection operation of a signal selection means outputting selectively a correction level signal and a reference level signal with one sampling clock of a correlation duplicate sample-and-hold circuit and applying the correction level signal to a signal synthesis means during a sampling period by the sampling clock. CONSTITUTION:A signal selection means 5 outputting selectively a correction level signal and a reference level signal makes selection operation synchronously with one sampling clock of a correlation duplicate sample-and-hold circuit 3 and applies a correction level signal during a sampling period by the sampling clock to a signal synthesis means, which adds the signal selected by the signal selection means to an image pickup output signal of a solid-state image pickup element. Since the level correction processing is implemented to the image pickup output signal, the cancellation of the correction level signal by the correlation duplicate sample-and-hold by the correlation duplicate sample-and-hold circuit 3 is avoided and the level correction processing is applied to the image pickup output signal.

Abstract: PURPOSE:To reduce in size a semiconductor device, to prevent the bonding part of a bonding pad to a wire from breaking down and to further prevent a signal from delaying by providing a peripheral circuit and the pad substantially at the center of a semiconductor chip, and employing a tabless lead frame. CONSTITUTION:A peripheral circuit 6 is provided at the center of a semiconductor chip 1, and bonding pads P1-P18 are concentrically provided along the long side of the circuit 6.

Title: Retrying system
Inventor: KUBOU KATSUMI
IPC: G06F9/30
Filed: 1982-12-31
Abstract: PURPOSE:To judge whether use is allowed or not when saved data is retried by providing an error display memory corresponding to the data saved lastly. CONSTITUTION:When error occurrence is detected, a flip-flop SVI-FF is set by an error signal appearing at the error detection terminal of a saving relating circuit. This flip-flop serves as the error display memory. A microprogram when judging that the memory should be returned to a state before instruction execution tests the flip-flop SVI-FF to confirm that it is set. When it is judged that data saved before the error occurrence is insignificant, the value of a saving counter SVC is subtracted by one. Then, memories MM0 and MM1 are turned to states before the instruction execution until the contents of the saving counter SVC attain to zero, and the retrying processing of the next instruction is performed.
