Title: Thin-film magnetic head and its production
Inventor: SATO KIYOSHI
IPC: G11B5/39
Filed: 1997-07-07
Abstract: PROBLEM TO BE SOLVED: To provide a thin-film magnetic head which is formed to improve light fringing or to sufficiently suppress the light fringing and may be easily produced without complicating the structure of the head and a process for producing the same. SOLUTION: A build-up part 1a is formed integrally with a lower core layer 1 on the lower core layer 1. The build-up part 1a is formed to a rectangular shape and the width size T1 of the build-up part 1a coincides with the width size Tw of the front end 7a of the upper core layer 7. The leak magnetic fields generated from the build-up part 1a and the front end 7a do not, therefore, protrude largely from the width size Tw which is a track width any more. The light fringing is thus suppressed. Since the light fringing is suppressed, the occurrence of tracking errors, etc., is prevented.

Abstract: PROBLEM TO BE SOLVED: To provide a single-phase or polyphase power converter which has a smaller switching loss when a switch is turned on. SOLUTION: A converter 1 constituted of switches Q1-Q6, diodes D1-D6, and capacitors C1-C6 is connected to an AC power supply AC through reactors L1-L3 for step-up. Between the output DC lines E1 and E2 of the converter 1, a capacitor C0 for soft switching is connected. A soft switching control circuit 3 having a reactor L11 and control switches Q11, Q12, Q13 is installed. The capacitor C0 is shorted for a specified period of time by means of the switches Q1-Q6. The rise and fall of the voltage VC0 of the capacitor C0 is sloped by the control of the control circuit 3. When the voltage of the capacitor C0 becomes nearly zero, a switch of the converter 1 is turned on.

Title: Recorder
Inventor: TAKANO KEIICHI
IPC: G01D15/24
Filed: 1997-07-08
Abstract: PROBLEM TO BE SOLVED: To enable highly accurate recording in a simple constitution by generating a signal for driving a motor from an operation result of outputs of an A/D converter and an encoder. SOLUTION: A microprocessor (CPU) adds or subtracts pulse counts of a d.c. signal Ei converted at an A/D converter AD and a feedback signal from an encoder (ENC), thereby generates a driving signal for a d.c. motor (DCM). A motor-driving circuit MD drives the DCM with the signal to move a pen (PN) of a recorder in a direction corresponding to the d.c. signal Ei. In consequence of the driving of the DCM, at this time, the ENC coupled to a rotary shaft of the DCM sends to the CPU a feedback signal of a pulse count proportional to a rotational angle. The CPU counts each pulse count of the feedback signal and d.c. signal Ei. When the former is smaller than the latter, the CPU keeps outputting driving signals. When the pulse counts become equal to each other to make an operation result 0, the driving of the DCM is stopped.  At this time, a position of the PN shows a value corresponding to the d.c. signal Ei, and the PN records the d.c. signal Ei.

Abstract: PURPOSE:To realize mode oscillation of a stable wavelength by a method wherein a stripe-shape current constriction region which has a plurality of wide parts and at least one narrow part and the wide parts are used as cavities and the narrow part is used as a coupling region between the cavities. CONSTITUTION:A Zn diffused layer 1 is formed into a sripe-shape whose wide parts are 10mum wide and 200mum and 300mum long and a narrow part is 3mum wide and 6mum long. By making an electrode 7 positive, positive holes are inject ed from the Zn diffused layer 1 into a GaAs activation layer 4. The positive holes are concentrated directly below the layer 1 by an n-type GaAs layer 2 and coupled with electrons from an electrode 8 to induce laser operation. The laser consists of two nearly independent cavities which are coupled by the narrow stripe pat. As the lengths of the cavities are different, the two cavities have different oscillation modes respectively and only the modes with wavelengths close to each other become common oscillation modes and a com plex cavity can be obtained and a stable mode oscillation can be realized. P-type and N-type Ga0.6Al0.4As cladding layers 3 and 5 confine injected positive holes and electrons and a laser light in the activation layer 4 to reduce the operating current.

Title: Picture reader
Inventor: WATANABE HIDETAKA
IPC: G06T1/00
Filed: 1986-08-04
Abstract: PURPOSE:To absorb the variation of the brightness of a light source and to more accurately grasp the brightness of a background by adding an addition and subtraction device to a storage device, increasing or decreasing the data in the storage device according to a signal which is considered as the background and slowly following the brightness of the background. CONSTITUTION:A comparison device 3 compares the stored data and an input signal and if the input signal is large in a certain range an addition command is outputted to the addition and subtraction device 8, if the input signal is small, a subtraction command is outputted respectively. The addition and subtraction device 8 receives the commands and adds a certain constant to the stored data in the storage device 4 in case of the addition command, in case of the subtraction command subtracts a certain constant to rewrite in the storage device 4. The constant of the addition and subtraction is smaller than a difference between an input peak value and a mentioned brightness of the background, so it selects the value which doesn't easily follow the temporary turbulence of the brightness of the background. The range of the addition and subtraction is set as the one where the device 8 fully follows the slow variation in a time but it doesn't follow a bit of picture information such as character, pattern, etc. Therefore the temporary turbulence of the brightness of the background is rarely followed and a read sensitivity can be highly stabilized.
