Title: Electrolytic chlorination for butadiene
Inventor: MATSUDA YOSHIHARU
IPC: C25B3/06
Filed: 1980-03-31
Abstract: PURPOSE: To progress reaction efficiently without lowering current density by allowing copper chloride to coexist in a nonaqueous system together with a chlorine source in electrolytic chlorination of butadiene.  
     CONSTITUTION: In chlorinating butadiene electrochemically in an electrolytic cell, copper chloride is allowed to coexist as a chlorine carrier in a nonaqueous solvent system such as polar aprotic or the like and electrolysis is performed by using a chlorine source such as zinc chloride. As an example for electrolysis conditions, the electrolysis is performed at the potential of anode around 1.68V at ordinary temp. with respect to a silver-silver chloride reference electrode. In this method, chlorination is accomplished efficiently even without using chlorine of high reactivity owing to the coexistence of copper chloride.

Title: Insulating method for squirrel-cage rotor
Inventor: ISHIKAWA TAKASHI
IPC: H02K15/12
Filed: 1982-03-15
Abstract: PURPOSE:To treat only necessary slot with insulation treating solution by introducing the solution from below to above of each slot of a rotor core, and then removing the solution in the slot from below the slot. CONSTITUTION:Insulation treating solution 11 filled in a tank 12 is fed uniformly downwardly without slot hole 5 through the ring-shaped groove 7 of a lower end plate 8 through a pipe 14 from an air piping port 15. When the solution 11 is filled in the entire length of the slot hole 5, the solution 11 reaches a detecting tube 17 through a doughnut-shaped groove 17 of an upper end plate 19. Thus, the air pressure in the tank 12 is released, and the solution 11 is returned to the tank 12. After the unnecessary solution 11 is entirely returned to the tank 12, the plate 9 is raised, the treated rotor core 4 is removed, and fed to a drying oven of the later step.

Title: Device for detecting abrasion of mold wall during casting process and use thereof
Inventor: BURUKUHARUTO KURISUTOMAN
IPC: B22D11/16
Filed: 1984-03-05
Abstract: An apparatus for determining the wear of a mold wall during continuous casting of metal by using at least one distance measuring sensor disposed in the mold wall to measure the instantaneous distance from the sensor to the casting. The surface of the casting adjacent the mold wall may be irregular, so the minimum value of the distance between the sensor and casting is stored and used as the current distance between the sensor and the inner mold wall. Mold wear is determined by subtracting the current distance between the sensor and the inner mold wall from the original distance, before the abrasive casting process began. The sensor signals are also used to determine when the mold geometry should be adjusted to compensate for the wear. This is accomplished by storing the maximum distance between the sensor and casting and subtracting the current distance from this maximum, since the maximum distance increases as the casting shrinks away from the mold wall.

Title: Magnetic recording and reproducing device
Inventor: OMIYA TAKESHI
IPC: G11B5/02
Filed: 1989-02-20
Abstract: PURPOSE:To prevent deformation of a recording signal waveform and a regenerative signal waveform due to cross talk of a rotary transformer by providing a means for short-circuiting each coil of the rotary transformer between each coil and recording and regenerative amplifiers to be connected to this coil. CONSTITUTION:Secondary side coils 12a-12d and 13a-13d of a stator 9 of the rotary transformer are connected with the recording amplifiers 16a-16d and the regenerative amplifiers 17a-17d respectively, and collectors and emitters of transistors 14a-14d and 15a-15d are connected to the secondary side coils 12a-12d and 13a-13d with both their ends as the short-circuiting means of a signal transmitting path between these secondary side coils 12a-12d and 13a-13d and the recording and regenerative amplifiers. When the secondary side coils 12a-12d and 13a-13d of the rotary transformer are short-circuited by the short- circuiting means, primary coils 10a-10d and 11a-11d of the rotary transformer are also short-circuited, thus becoming these coils effective as a shield material. Consequently, a recording current is prevented from leaking into the signal transmitting path of a long time mode head and being recorded due to the cross talk of the rotary transformer at the time of recording.

Filed: 1988-02-23
Abstract: PURPOSE:To shorten the maximum pulse width of an information signal to improve the display contrast by applying a prescribed preceding pulse before applying a scanning select signal. CONSTITUTION:When the scanning select signal having a pulse having one polarity and a pulse having the other is applied to at least one scanning electrode, a preceding pulse PT0 lower than a threshold voltage which is determined by the pulse waveform, the pulse width, and the pulse crest value is applied to at least one other scanning electrode within an application period T1 of first one of said pulses to set a maximum pulse width DELTAT of information signals I1, I2... to a short value, for example, 60musec or shorter. As the result, great coupling is caused by a dielectric constant anisotropy DELTAepsilon of ferroelectric liquid crystal between matrix electrodes to improve the display contrast.
