Title: Magnetic head
Inventor: FUKUHARA YOSHIKAZU
IPC: G11B5/17
Filed: 1981-10-02
Abstract: PURPOSE:To minimize the size of a magnetic head, by forming a notched part to the side face of a shielding case of the magnetic head at the chassis side and drawing out an external terminal through the notched part. CONSTITUTION:A notched part 2b is formed at the rear edge of a side face 2a of a shielding case 2 at the chassis side. Then an external terminal 4 is drawn out through the part 2b and toward the chassis, and the base edge part of the terminal 4 is molded with a resin 10. Thus the terminal 4 never protrudes to the back of a magnetic head 1. This can decrease the whole length of the head 1. As a result, the size of the head 1 is minimized.

Title: Main circuit for regenerative brake system of ac electric rail car
Inventor: MIURA AKIZUCHI
IPC: B60L7/12
Filed: 1987-06-23
Abstract: PURPOSE: To eliminate transformer and converter for regulating unbalanced current between two parallel units, by setting a reactor with a mid-point, between a transformer and a converter.  
     CONSTITUTION: The primary winding P of a main transformer T is electrically conducted via a pantograph PT through an aerial conductor CW. In the meantime, a secondary winding is divided into L 1 'WL 4 ', and to the windings L 1 'WL 3 ', main thyristor bridges MRf 1 'WMRf 3 ' are connected, and to the winding L 4 ', the thyristor bridges MRf 41 'WMRf 42 ' of 1/2 current capacity are connected. Besides, on the counter thyristor side of the winding L 4 ', a reactor BL with a mid-point is connected. As a result, when current amounts I 1  and I 2  flowing between two sets of parallel armatures(A 11 WA 14  and A 21 WA 24 ) are turned unbalanced, then circulating current flows due to the action of the reactor BL with the mid-point so that I 1 =I 2  may be set.

Title: Bar code printer
Inventor: FUKUMOTO MITSUO
IPC: B41J3/01
Filed: 1989-06-19
Abstract: PURPOSE:To allow bar codes with a patterning accuracy to be printed without less ink run even on a surface with a slight unevenness such as that of a corrugated cardboard box by causing recording material on a light beam projecting section to react thermally or evaporate based on bar code data which is read from memory. CONSTITUTION:A projection and scanning control section 11 projects a laser beam and scan data using the beam by controlling a laser beam projecting device 12 based on bar code data stored in bar code data memory 10. A recording material is already applied as a coat on a surface where a bar code should be printed of a commodity 1 when a laser beam is projected. If the recording material is a thermosensitive recording material, heat energy is given to the recording material by projection and scanning of the laser beam from the laser beam projecting device 12. Consequently, a thermal reaction occurs resulting in a color development. In addition, when a recording material is one which evaporates due to heating such as color paint, a laser beam projecting section evaporates to expose a background color, and thus a bar code pattern is formed. Bar codes with high accuracy can be printed easily on the surface of a corrugated cardboard box.

Title: Bit synchronizing circuit
Inventor: KITAGUCHI TAKAHISA
IPC: H04L7/02
Filed: 1985-07-15
Abstract: PURPOSE:To easily attain a synchronization by comparing the phase of an input signal with the phase of the fundamental clock signal of a fundamental frequency component of the input signal, and energizing one of two pieces of LPFs by the lead and lag of its output. CONSTITUTION:When a CMI signal is inputted to a phase comparator 1, FF 10 and 11 detect the CMI signal at the leading and at the trailing of a fundamental clock pulse, and generate signals A, B. The signals A, B become signals C, D through NOTs 12, 13 and ANDs 14, 15. A gate 4 takes ANDs 17, 18 by an output of the NOT circuit 16 of the CMI signal and the signals C, D, and erases unnecessary signals C (D) which are generated due to the difference of a rise of the CMI signal. LPFs 2b (2a) are energized by the remaining signals D (C), and the phase of a counter 3 is made to lead or lag. In this way, the time for securing a synchronization with a bit of not only a usual binary signal but also a signal whose leading is different at every bit such as the CMI signal is quickened.

Abstract: PROBLEM TO BE SOLVED: To make the difference of the luminance of an entire light transmissive cylindrical body small, to prevent inside temperature rise, to facilitate maintenance inspection and to effectively utilize light by constituting the light transmissive cylindrical body separately from a light source housing body and connecting them through a light transmission body. SOLUTION: The light transmissive cylindrical body 11 is constituted separately from the light source housing body 12 constituted by arranging a light source 13, and the housing body 12 and the cylindrical body 13 are connected through the light transmission body 15. Acrylic resin, for instance, is used for the cylindrical body 11, and the light source 13 is constituted by using a high pressure discharge lamp of about 150W, for instance. The light transmission body 15 for conducting the light from the housing body 12 to the cylindrical body 11 is constituted by using a liquid pipe constituted by injecting photocondictive viscous liquid inside. Thus heat generated from the light source 13 is hardly propagated to the cylindrical body 11, and the cylindrical body 11 is easily produced by using the acrylic resin.  Since the temperature rise of the cylindrical body 11 is restrained, it is safely used.

Abstract: PURPOSE:To attain a bidirectional simultaneous call system in a simple constitution by providing the electro-optical/photoelectric transducer means to both master and slave devices and switching periodically the transmission and reception states in a short time with use of the photodetecting effect of a light emitting diode. CONSTITUTION:A clock oscillator 32 produces the clock signals, and a timing circuit 34 receives the clock signal and produces a transmission/reception changeover pulse to supply it to a transmission/reception switch 20. The switch 20 switches the transmission and reception states of an electro-optical/photoelectric transducer 16 in response to the received pulse and then switches the emission and reception of light of a light emitting diode in a short time to transmit and receive the signals. In addition, the switch 20 transmits and receives the light in a pulse shape according to the intensity of the voice signal and synchronously with the transmission and reception of signals. Therefore the bidirectional optical communication is attained with use of a single light emitting diode and at the same time the voice signals can be transmitted and received. In such a constitution, a bidirectional simultaneous call system is available just with a single optical fiber cable and in a simple constitution.
