Title: Manufacture of galvannealed steel sheet
Inventor: KOIKE TOSHIAKI
IPC: C23C2/06
Filed: 1990-08-20
Abstract: PURPOSE:To obtain a galvannealed steel strip excellent in powdering resistance and flaking resistance by regulating the concn. of Al in a zinc bath, the time for immersing a steel sheet in the zinc bath or the like. CONSTITUTION:At first, the amt. of Al to be added to a zinc bath in which a steel strip is immersed is limited to 0.02 to 0.11%. In a steel sheet to be immersed in the zinc bath, its sheet temp. is regulated to 420 to 450 deg.C. In the case of <420 deg.C, the reaction of alloying (Fe-Zn) is oversuppressed, so that there occurs a case wherein ungalvannealing is generated. Furthermore, in the case of >450 deg.C, the reaction of alloying (Fe-Zn) is overadvanced, so that the formation of a GAMMA-phase at the time of alloying progresses to deteriorate its powdering resistance. The time for immersing the steel sheet in the zinc bath is regulated to <=3sec. Moreover, the temp. in the alloying treatment is regulated to 550 to 600 deg.C for preventing the generation of coarse (Zn-Fe) xsi-phase crystals on the surface of the galvannealing and forming a xsi-phase of fine crystals. In the obtd. galvannealed steel sheet, the generation of a GAMMA-phase in the galvannealed layer is small and a xsi-phase on the surface of the galvannealing is also refined, so that its powdering resistance and flaking resistance are made excellent.

Title: Sinusoidal half wave pulse generator
Inventor: KADOTA SANAE
IPC: H03K3/352
Filed: 1987-08-31
Abstract: PURPOSE:To generate a sinusoidal half wave pulse current whose current inverting rate is 5% or below with a narrow pulse width by connecting a forced commutation thyristor switch in parallel with a load coil. CONSTITUTION:A capacitor C is charged to a voltage E to trigger an application thyristor switch SCR 1. A load current (i) is a sinusoidal wave and a capacitor voltage VC is a cosine wave. In triggering a forced commutation thyristor switch SCR 2 with the load current (i) at zero and the capacitor voltage VC at -E, the electric charge in the capacitor at a voltage of -E causes a reverse current irr with a fast leading to flow to the application thyristor SCR 1 in the opposite direction via the forced commutation thyristor switch SCR 2. The reverse current irr absorbs rapidly the storage carrier of the application thyristor switch SCR 1 and the load current (i) is interrupted rapidly.

Title: Speed change controller for automatic transmission
Inventor: IIZUKA NAONORI
IPC: F16H61/00
Filed: 1988-09-02
Abstract: PURPOSE:To dissolve the trouble in the traveling stability and noise by selecting the first down shift line up to the lapse of a prescribed time from the operation to the engine brake position of a selecting device and selecting the second down shift line after the lapse of a prescribed time. CONSTITUTION:When an engine brake position is selected by operating the selecting device such as selecting lever and an overdrive prohibiting switch, a down shift line selecting means selects the first down shift line during a prescribed time, and speed change is carried out. After the lapse of a prescribed time, selection to the second down shift line is perform. Since the second down shift line is set to the lower speed side in comparison with the first down shift line, down shift speed change can be carried out simultaneously with the selection operation on the higher speed side, and the drive feeling can be improved. When selection operation is carried out on the higher speed side than the first down shift line, down shift speed change is carried out on the second down shift line, and the deterioration of safety and drive feeling can be prevented.

Title: Switching drive type brushless motor
Inventor: SAKAMOTO SATOSHI
IPC: H02P6/08
Filed: 1985-10-01
Abstract: PURPOSE:To reduce the vibrations and noises of a motor, and to obtain stable torque by weakening a drive signal by a CR time constant circuit while bringing the phase of the detection of the position of a rotor to the phase of lead in response to the quantity of delay of the CR time constant circuit. CONSTITUTION:A drive circuit for a brushless motor is provided with a CR time constant circuit consisting of a capacitor C1 and a resistor R1, which makes the waveform of a rotational-position detecting signal from a rotor gentle and forms a switching drive signal. Consequently, the vibratory noises and electromagnetic noises of the motor are reduced. The detecting point of a rotational-position detecting signal by a rotor-position detecting section is set to the phase of lead in response to the signal delay time by the CR time constant circuit. Accordingly, displacement from an ideal switching point of driving currents is compensated, thus compensating the steep lowering of torque.

Filed: 1995-08-28
Abstract: PROBLEM TO BE SOLVED: To efficiently restore a building from inclination using a bag by mounting the bag in U-shaped formwork molded into an approximately U-shaped cross section consisting of upper and lower forms, and placing the formwork between the ground and the lower surface of a foundation where unequal settlement has occurred. SOLUTION: If a building 41 is inclined as the result of unequal settlement of the ground 39 beneath a foundation 43 due to an earthquake, etc., the ground 39 beneath the foundation 43 is dug to provide a pit 45 large enough to insert formwork 15. The formwork 15 enclosing a bag 27 is placed in the pit 45, a hardening material is injected into the bag 27 from a pump, and then the bag 27 is inflated while making close contact with upper 17 and lower 19 forms and gradually raises the form 17 so that the form 17 restores the building 41 from inclination as it is pressed into contact with the lower surface of the foundation 43, The amount of unequal settlement of the building 41 can be dealt with by varying the amount of maximum movement of the form 17 through variations in the size of the bag 27 and the length of an oblong hole 23,  and the building 41 can be efficiently restored from inclination since the bag 27 is always held in a fixed shape by the forms 17, 19.

Filed: 1982-12-13
Abstract: PURPOSE:In the production of isoprene by reaction of a starting material such as isobutene with formaldehyde under specific conditions, at least a part of the starting material is heated together with the reaction mixture which is taken out of the reactor, then introduced into the reactor to obtain the objective compound advantageously. CONSTITUTION:In the one-stage production of isoprene where isobutene and/or tert.-butanol, as a starting material, and a formaldehyde resource and water are continuously introduced into the reactor containing acidic aqueous solution and the isoprene, water and other low-boiling components are distilled out of the reaction system, a part of the acidic solution is taken out of the reactor and heated together with at least a part of the starting materials mentioned-above, then introduced into the reactor. Thus, the increase in side-reactions which are caused by overheating is inhibited to prevent the reduction in the yield of the objective compound. At the same time, a necessary amount of heat is effectively fed to produce the objective compound advantageously.
