Title: Production of alkyl chloride
Inventor: YAMAGIWA SHUICHI
IPC: C07C17/00
Filed: 1985-02-28
Abstract: PURPOSE:To obtain the titled substance useful as a raw material of cationic surfactant, etc., continuously, easily, in high yield, without necessitating the regeneration of the catalyst, by using zinc chloride in the form of a hydrochloric acid solution as a catalyst and contacting an alkyl alcohol used as a raw material with hydrogen chloride. CONSTITUTION:An alkyl alcohol (e.g. n-propyl alcohol, sec-butyl alcohol, etc.) and (anhydrous) hydrogen chloride are introduced at a molar ratio of 1:(1.1-1.5) continuously into a hydrochloric acid solution of zinc chloride maintained at the reaction temperature, and the components are made to contact with each other in the solution. The reaction product is immediately distilled out of the system to obtain the objective compound in vapor phase. The above catalyst can be produced by mixing zinc chloride with equimolar amount of an aqueous solution of hydrochloric acid. It is preferable to add the alkyl alcohol to the catalyst solution (1mol of the alcohol per 1mol of zinc chloride) to attain the stationary operation in a short time.

Title: Method and apparatus for ultrasonic wave reception
Inventor: YOSHIDA YUKIO
IPC: G01S7/527
Filed: 1981-03-20
Abstract: PURPOSE:To measure the propagation time of an ultrasonic wave accurately, by removing an abnormal value through the overall judgment of elements of an ultrasonic wave reception signal such as amplitude, waveform and arrived position. CONSTITUTION:An ultrasonic wave pulse transmitted from a transmitter (not shown) is converted into an electric signal at a receiver of an ultrasonic wave receiver via a propagation medium, amplified at a reception ampliier 1 and applied respectively to a peak level comparator 2, a zero selection comparator 7, and a zero cross comparator 6. In case of a reception waveform as shown in solid lines in Fig. (a), a zero cross pulse (d) is outputted by one at a location after the peak wave and it is judged that the arrival time of the reception wave can be regarded as the leading of the zero cross pulse (d). If the amplitude of the reception wave due to any cause exceeds a value Vzs as shown in broken lines in (a) before the peak wave, since the zero cross pulse (d) is produced as shown in the broken lines, this pulse signal is regarded as failure and not transmitted to a processing circuit 10.

Abstract: PURPOSE:To secure the load and removal of the cassette with high controllability and working efficiency by closing the switch of the pinion driving motor before intermeshing between the motor-driven ejection idler of the cassette and the pinion. CONSTITUTION:With push of pause/ejection button 193, the lock is released for the operation button under operation to set the recorder/reproducer under the pause mode. In this mode, if button 193 is pressed furthermore, slider 204 shifts to give turns to lock arm 14. As a result, the intermeshing is secured between idler 18 and pinion 10. Prior to this intermeshing, switch 27 is closed via arm 14, and pinion 10 is turned by the motor before intermeshing of idler 18. Thus the tooth tips touch to each other between pinion and idler 18 to avoid the incomplete intermeshing, and then cam gear turns via idler 18. And thus the motor-driven ejection is ensured to the cassette via the cam unified to gear 33 and others. So is with loading of the cassette. In such way, the cassette can be loaded and removed in the high controllability and working efficiency.

Title: Measuring method of shape of triolobe
Inventor: OKAZAKI YUKIYOSHI
IPC: G01B21/00
Filed: 1991-03-07
Abstract: PURPOSE:To correctly obtain the largest inscribed circle and the smallest circumscribed circle of a trilobe by constructing coordinates data of the peripheral surface shape, setting three areas with which the inscribed circle and the circumscribed circle are presumed to be in touch based on the coordinates data, and obtaining a virtual center point and contact points. CONSTITUTION:After the rotary shaft of a spindle 3 is agreed with the center of a trilobe, the spindle 3 is rotated and measured at, 4. The dimension xsi(thetai) in the radial direction of the trilobe measured at 4 and the rotating angle thetai of the spindle 3 encoded at 5 are constructed along with the measuring center of the trilobe by a computer 11 to a coordinates data. After the construction, the largest inscribed circle and the smallest circumscribed circle of the trilobe are obtained. The process to obtain the smallest circumscribed circle is the same as that for the largest inscribed circle and therefore the explanation is abbreviated. Since the minimum radius gammao-a of the trilobe in design is at 90 deg., 120 deg., 330 deg., the actual minimum radius is presumed to be also in the vicinity of the above. An area to which the largest inscribed circle is presumed to be in contact, is set in the vicinity of the three points. A point with which the largest inscribed circle is actually held in contact is searched within the area. In this manner, the largest inscribed circle can be positively obtained.

Abstract: PROBLEM TO BE SOLVED: To easily discriminate whether the non-drive of a load is caused by the failure of a circuit breaker or the failure of the load based on the presence or absence of an excitation display by displaying that multiple circuit breakers are set to the excitation state with an excitation indicator. SOLUTION: When a circuit breaker 1b is tuned on, an exciting current flows in the coil 33 of a relay 3, a normally opened contact point 34 is closed, and electric power is fed to an excitation indicator 4 to turn on a light emission diode 37 if a circuit breaker 1a is set to the on-state. When one of the circuit breakers 1a, 1b is kept at the off-state, the excitation indicator 4 is not excited, and the light emission diode 37 is turned off. When the circuit breakers 1a, 1b are set to the on-state, excitation is displayed by one excitation indicator 4. If at least one of the circuit breakers 1a, 1b is turned off or tripped, no excitation display is available. When a load is not driven, whether the trouble is caused by the circuit breakers 1a, 1b or by the load can be easily discriminated.
