Title: Neutron detector
Inventor: ENDOU HIROSHI
IPC: G01T3/00
Filed: 1980-03-31
Abstract: PURPOSE:To make it possible to measure a distribution of neutron flux density by use of one detector, by inserting an collector electrode consisting of a resistor in a long slender body whose inside surface has been covered with a counter tube working substance, and dividing the inside of the body by a collimator. CONSTITUTION:When a neutron is made incident into the cell 11 of the neutron detector, this neutron reacts to a counter tube working substance in a working film in the cell 11, and alpha particles or Li particles of a recoil residual nucleus 7 are emitted. Since these respective cells 11 are divided by the collimator 10, respectively, the range of such charged particles is controlled in the cell 11 into which the neutron has been made incident, and a plasma sheath produced in the body is limited in the cell 11. And, an electron in this sheath is collected ino the collector electrode 7 in the cell 11, and a pulselike current is obtained. In this regard, since the electrode 7 has a prescribed resistance value, the peak value of a pulselike current corresponds to a distance extending from the lower end of the electrode 7 to the cell 11 into which a neutron has been made incident. Accordingly, the cell concerned can be known by detecting the peak value of this pulse.

Abstract: PURPOSE: To provide a distance measuring apparatus wherein the circuit constitution is simplified to contrive low-cost production, and its distance measuring accuracy is enhanced by a method wherein a received pulse signal is integrated and processed and a correction value is set on the basis of its peak value. CONSTITUTION: Reflected laser pulse light which has been reflected by an object is received so as to be inputted as a light-received signal. The light-received signal is integrated by an integration peak hold circuit 12 in a light-receiving intensity detection circuit 11, and its peak voltage value is held by a capacitor C as the magnitude of a received luminous intensity. The integrated peak voltage value is converted into a digital value by an A/D converter 14 via a voltage follower 13, and, in a distance measuring part, it is operated to be a time correction value corresponding to the integrated peak voltage value (received luminous intensity).  In addition, the time which elapses from a light-emitting operation up to a light-receiving operation and which is measured by a time measuring part is corrected on the basis of the time correction value, and the time which has been corrected is converted as a distance up to an object. When a distance measuring operation is finished, a switch 16 for discharge is operated so as to be turned on by a reset signal, and the hold of the integrated peak voltage value is stopped.

Title: Device for detecting welded part of metallic material
Inventor: FUJIMOTO MINORU
IPC: G01B17/00
Filed: 1981-03-25
Abstract: PURPOSE:To detect welded part simply without contact, by using two probes which give ultrasonic wave signals to the metallic material and detect the reflected waves and detecting the difference between the detected levels of both probes. CONSTITUTION:A steel pipe 1 having a welded part 2 is rotated at a slow speed. The probes 3A and 3B are constituted by a winding of a core which is excited by a DC power source 4 and a transmitting and receiving winding to which a pulse current is supplied by a pulse generator 5. When the pulse current is applied to the transmitting and receiving winding under the state the DC magnetic field is applied to the steel pipe, varying distortion is formed on the surface of the steel pipe and propatated to the inside as an ultrasonic wave. The reflected wave from the inside is detected by the transmitting and receiving winding and inputted to amplifiers 6A and 6B. When the welded part 2 faces one of the probe, the difference between the detected signal levels of both probes is generated because the attenuation of the ultrasonic wave at the welded part is large. Said difference is detected by subtracting circuit 7, an integrating circuit 8, and a comparator 9, and a relay 10 is driven.

Title: Control method for air conditioner of vehicle
Inventor: SASAKI AKIHIRO
IPC: B61D27/00
Filed: 1990-02-26
Abstract: PURPOSE:To suppress the rise of room temperature due to interruption of power within a preset upper limit value and to prevent a passenger from feeling that cooling is insufficient by controlling the room temperature which rises until a compressor is restarted after the interruption of power not to exceed an upper limit value used in ordinary on-off control at the time of restarting the compressor. CONSTITUTION:At a spot where the power is interrupted, if the room temperature at the spot is lower than (v) point, even if the room temperature rises with a gradient theta1 during the time t2 from when it passes (i) point of the same spot until a compressor is restarted, (v) point is a temperature which will not exceed (vi) point, that is, the room temperature upper limit value TH. If the room temperature satisfies a room temperature upper limit pattern from two points to (v) point, two points show points such that at the power interruption point (i), the room temperature is (v) point always within the range of cooling capacity (gradient theta2) of the compressor. That is, when the control is made in the room temperature upper limit value pattern in the section near the power interruption spot, the room temperature can be always lowered to a designated temperature at the sport (i), and then if the time t2 until the compressor is restarted elapses, the room temperature will not rise above the room temperature upper limit value, so that comfortable temperature control can be accomplished.
