Title: Controller of electric railcar
Inventor: SAKAI HIDEO
IPC: B60L7/24
Filed: 1985-07-08
Abstract: PURPOSE:To reduce the wear of a brake shoe by switching a pneumatic brake to a generative brake in response to the state of a regenerative load. CONSTITUTION:When a brake instructing unit 1 applies a brake command if a regenerative load sufficiently exists, the unit 1 is connected through switching circuits 9, 4 with a regenerative brake unit 5 to allow a regeneratively braking. If the regenerative load is 0 or extremely small, the output of a regenerative current detector 7 decreases from a reference current value before the switching operation of the switching circuit 4 due to a trolley wire voltage rise to switch the circuit 9. Thus, when the unit 5 is released, the unit 1 is simultaneously connected with a generative brake unit 10 to allow a generative braking. Accordingly, the trolley wire voltage does not rise to eliminate the switching operation of the circuit 4.

Title: Method for orienting substrate for liquid crystal display device
Inventor: KONYA TOMONORI
IPC: G02F1/1337
Filed: 1996-05-17
Abstract: PROBLEM TO BE SOLVED: To relieve rubbing conditions and to suppress the occurrence of static electricity and flaws in a method for orienting substrates for a liquid crystal display device. SOLUTION: An org. orienting agent 3 is first applied on the surface of the substrate 1 of the liquid crystal display device formed with at least electrodes 2 by executing a coating stage. Next, the substrate is calcined at a relatively low temp. by executing a calcination stage and the org. orienting agent applied on its surface is half cured to form an org. oriented film 3a. In succession, orientability is imparted to the liquid crystal molecules by rubbing the org. oriented film 3a in a specified direction by a buff material 5 by executing a rubbing stage. Finally, the substrate 1 is normally calcined at a relatively high temp. by executing a normal calcination stage, by which the org. oriented film 3a is completely cured and the film quality thereof is stabilized.

Filed: 1980-10-23
Abstract: PURPOSE:To reproduce a high-quanlity still picture, by reproducing video signals of the same field from a disc information recording medium where video signals are recorded. CONSTITUTION:For a disc information recording medium where four-field components of video signals are recorded for every one rotation, reproducing heads P1- P3 and one recording head R are provided, an heads P1 and P3 and heads P2 and R face to each other, respectively.

Title: Ink ball impact means for printing
Inventor: YANO TAKESHI
IPC: B41J2/22
Filed: 1986-06-24
Abstract: PURPOSE:To apply impact force at a short repeating cycle with high energy conversion efficiency, by mounting a transmission mechanism for amplifying and transmitting the dimensional strain of a piezoelectric element responding to a drive signal and a driving pin responding to the dimensional strain to impart impact force to an ink ball. CONSTITUTION:A piezoelectric element 22 responds to a drive signal of printing timing to generate elongation dimensional strain in the direction of an arrow E and transmits said strain to levers 23, 24 connected to the other end of said element 22 through hinges. Since the levers 23, 24 are respectively connected to a base 21 through the hinges, displacement is generated at the leading end parts of said levers in the directions of arrows F, G and transmitted to a lever 25 through the respective hinges to generate displacement in the driving pin 20 mounted to the lever 25 in the direction shown by an arrow B. As a result, the driving pin 20 imparts impact force toward the ink ball 1 supplied into a nozzle 3 being a jet pipe as shown by an arrow A. Since a drive source is the piezoelectric element 22, driving can be performed at a short repeating cycle and, further, since electrostriction vertical effect is utilized, impact force can be applied with high energy conversion efficiency.

Title: Magnetic head for super resolution magneto-optical recording medium and magneto-optical recording device
Inventor: MIYAKE TOMOYUKI
IPC: G11B5/02
Filed: 1998-05-29
Abstract: PROBLEM TO BE SOLVED: To prevent reducing recording magnetic field sensitivity of a recording layer caused by adding a reproduction layer being a magnetic super resolution film, and to permit compatibility of improving a reproducing characteristic of a short bit by masking with high recording magnetic field sensitivity by setting a magnetic core cross section larger than the prescribed area at which recording magnetic sensitivity starts to reduce. SOLUTION: Recording magnetic field sensitivity of a super resolution magneto-optical recording medium is varied by a magnetic core cross section used for magnetic field modulation recording, recording magnetic field sensitivity can be improved by making a magnetic core cross section a fixed magnitude or more. In the super resolution magneto-optical recording medium, when a magnetic core cross section becomes 0.08 mm, C/N saturation magnetic field intensity begins to reduce from 240 Oe. In other words, when a magnetic core cross section becomes more than 0.08 mm, C/N is saturated even by less recording magnetic field. Thereby, in the super resolution magneto-optical recording medium, magnetic field intensity required at the time of recording can be made less by making a magnetic core cross section larger than 0.08 mm.

Surface of the bag 1 is wet by the surface active agent and an alkali, and the outer layer 12 is solved or decomposed.
