Title: Phase-locked loop circuit
Inventor: KATO KENICHI
IPC: H03L7/14
Filed: 1999-04-13
Abstract: PROBLEM TO BE SOLVED: To oscillate a voltage controlled oscillator(VCO) with a frequency and a phase at the time of synchronizing even when a reference frame signal is abnormal. SOLUTION: When a frame signal 22 is normal, a switch 7 is connected to the side of a low-pass filter 106 and a VCO 108 is oscillated at the frequency synchronized to the frame signal 22 by feedback control. In the state of weakening a received radio wave and making the frame signal 22 abnormal, since the voltage of an RSSI signal 21 expressing radio wave strength is lowered as well, the output signal of a comparator 10 is inverted, the switch 7 is connected to the side of a voltage storage part 12 and a switch 13 is turned off. As a result, a control voltage stored in the voltage storage part 12 at normal time is supplied to the VCO 108 and the VCO 108 continuously oscillates at the same frequency and phase as the normal time.

Title: Metal cutting tool
Inventor: YAKOBU HARUPAZU
IPC: B23Q1/00
Filed: 1992-04-01
Abstract: PURPOSE: To facilitate the use of flow of cooling fluid to limit the wear of a cutting edge on one hand and remove cut metal chips on the other hand by forming a through bore in an insert. CONSTITUTION: When a metal cutting tool is used in the work of parting a workpiece 17, cut metal chips 18 immediately after shearing are deflected upward by passing over a planar land face 11 and chip deflecting faces 13a, 13b. At the same time, a cooling fluid flow 19 passes through an insert bore 15, effectively fills a cavity formed by a recessed portion 12c, and swells to collide against the lower face of the center portion of the chip. The action of the cooling fluid flow 19 is essentially dual. On one hand, it effectively cools an insert 21 essentially in the region of a cutting edge 10, thereby reducing the wear of the cutting edge 10 and thus extending effective operating life. On the other hand, the flow 19 contributes to the effective upward deflection of the chip 18 from the cutting tool and the workpiece 17.

Title: Optical head device
Inventor: TATSUZONO FUMIO
IPC: G11B7/003
Filed: 1989-04-25
Abstract: PURPOSE:To prevent a bit error due to dust from occurring by providing a second head to converge a beam on the same part of a recording layer by irradiating at a different angle other than a head irradiating with the beam at prescribed angle. CONSTITUTION:Light by the head irradiates the side of a transparent substrate 6 with thickness of 20mum of an optical tape 5 consisting of the transparent substrate 6, a recording layer 7, and a protecting layer 8. A first head 1 is provided so that the beam can be made incident perpendicularly to the tape 5, and when the beam is converged to the one with a diameter of 1mum on the recording layer 7, the diameter of the beam on the surface of the substrate 6 goes to around 20mum. When the light emitting side 2 and the light receiving side 3 of the second head are provided so as to form an emitting/incident angle of 45 deg. against the tape 5, the emitting/incident point on the surface of the substrate 6 is deviated sideways by around 20mum from the emitting/incident point of the head 1. Therefore, the beam of the head 2 can be prevented from being shielded even that the beam from the head 1 is shielded by the dust on the surface of the substrate 6. In such a way, an optical head device without generating the bit error due to the dust can be obtained.

Title: Waveform correcting circuit for received dial pulse
Inventor: ARAI MASANOBU
IPC: H04Q1/32
Filed: 1985-05-17
Abstract: PURPOSE:To reproduce a strict square wave to a dial interruption in an exchange by actuating a voltage supplying circuit at the transition from dial make time to break time and by disconnecting the said circuit when the terminal voltage of a capacitor becomes of a specified value. CONSTITUTION:A comparator (CMP) 1 outputs a dial pulse waveform that makes a voltage V1 of the maximum value. A CMP 2 detects the shift from the make time to the break time at an output terminal B. During the break time, the voltage suppling circuit CHG 5 supplies a current to the terminal B and charges the capacitor C. Meanwhile, a CMP 3 sets a flip-flop FF 4 when the voltage reaches a comparison voltage V3, and a decircuiting circuit DSC cuts off the current. In result, the output waveform shown by the full line in the figure is obtained overcoming the conventional practice where there was an unnecessary pulse shown by the broken line because of the distortion due to the excess current at the break time.
