Patent JP-H08162926-A (JP)
Title: Phase comparator circuit
Inventor: KOBAYASHI TOSHIAKI
IPC: H03K5/26
Filed: 1994-12-01
Abstract: PURPOSE: To easily perform incorporation to a digital LSI, to widen a phase comparable range and to perform operations to a high frequency by providing an AND circuit for outputting the AND of the output of a first latch circuit and the output of a second latch circuit. CONSTITUTION: When the output of a frequency divider circuit 4 is respectively inverted by the rise of an input signal S1, a latch circuit 5 which outputted '0' is set and Q output becomes '1'. Also, the setting of the latch circuit 6 is canceled, however, the previous '1' is outputted until the input signal S2 rises. In this case, the output signal S7 of the AND circuit 7 outputs '1' in synchronizing with the rise of the signal S1. Then, since the '0' of the latch circuit 6 is outputted when the signal S2 rises, the output signal S7 of the AND circuit 7 outputs '0' in synchronizing with the rise of the signal S2. Thereafter, since the state is repeated, the signal S7 for outputting '1' at the rise of the signal S1 and outputting '0' by the signal S2 is obtained.  Thus, since pulses corresponding to the phase difference of the two input signals are outputted, the phase comparison is performed.

Title: Optical waveform generator
Inventor: YAMASHITA TAKASHI
IPC: H03B28/00
Filed: 1995-11-16
Abstract: PROBLEM TO BE SOLVED: To allow the generator to read an optional waveform drawn on an original and to provide an output of the waveform with high accuracy. SOLUTION: An original 1 on which an optional waveform is drawn is placed closely to a sensor panel 2 consisting of a 2-dimensional matrix photo cell group and a light from a light source 3 is made to irradiate the original 1 and its reflected light is given to the sensor panel 2, then the waveform is mapped onto the sensor panel 2. A scanning section 5 scans the sensor panel 2 to obtain a current signal representing a position of a photo cell receiving waveform information, the current, is converted into a voltage by a current/ voltage conversion section 6, a comparator section 8 compares the voltage with a reference voltage. When the result of comparison indicates a high level information voltage, the processing section 8 provides an output of a count stop signal (c) to a counter 9.  The counter 9 counts the clocks of the scanning section 5 and a position signal of the waveform is obtained by the count stop. A waveform information signal is obtained by using a D/A converter section 11 to convert the position signal into an analog signal.

Title: Printed circuit board for mounting electronic part
Inventor: ISHII HIDETO
IPC: H05K3/28
Filed: 1996-11-11
Abstract: PROBLEM TO BE SOLVED: To prevent the separation of a metal thin film from a supporting board when the large separating stress is applied on an electronic part, which is soldered to the printed circuit board for mounting the electronic part. SOLUTION: A metal thin-film pattern 2 is formed on a supporting board 1. The edge of the pattern is covered with a solder resist film 3. Thus, the reaching of the fused solder to the edge of the pattern is prevented in soldering. Even when the large separating force is applied on the electronic part, which is fixed by soldering, only the small separating force is applied on the edge of the pattern. Thus, the separation of the metal thin film pattern 2 from the supporting board 1 does not occur.

Title: Reader
Inventor: OGATA KOHEI
IPC: H04N1/40
Filed: 1987-11-28
Abstract: PURPOSE:To surely prevent the soil of a reference body and to improve a picture quantity by moving the reference body to readable position only at the time of obtaining information for executing a correction related to an optical reading. CONSTITUTION:For example, a moving means is driven before the reading of an original is started, a reference body 7 is moved to the readable position, and correction information related to the optical reading is obtained. When the gathering of the information related to the correction is completed, the reference body 7 is moved from the reading position by the moving means. Consequently, at the time of reading the original, while an original 3 is not in contact with the reference body 7, the soil of the reference body 7 can be prevented. In such a way, by the reference body 7 without the adhesion of the soil, the correction, for example, a shading correction, etc., can be properly executed.

Title: Microstrip line filter and center frequency adjusting method thereof
Inventor: TANAKA HIDEAKI
IPC: H01P1/205
Filed: 1997-10-15
Abstract: PROBLEM TO BE SOLVED: To obtain satisfactory yield by forming a dielectric layer for adjustment covering at least the whole resonator of a microstrip line and then enabling adjustment of the center frequency to allow deviations in pattern size and a dielectric substrate specific dielectric constant within specific ranges. SOLUTION: When the thickness and shape of a dielectric substrate 2 of a microstrip line filter 1 and the resonance pattern length of a pattern circuit 3 on the dielectric substrate 2 have errors, variance in center frequency is generated. Here, the whole resonator 7 except input/output lines 5 and 6 at both the ends of the pattern circuit 3 on the dielectric substrate 2 is covered with the dielectric layer 10 for adjustment. Thus a dielectric layer 10 for adjustment is added, and then the center frequency shifts to the low frequency side. The necessary center frequency is shifted and becomes adjustable by properly selecting the thickness and material, therefore, specific dielectric constant of the dielectric layer 10 for adjustment. Furthermore, a connection with an external cable run is facilitated by making the input/output lines 5 and 6 open.

IPC: B60C11/18
Filed: 1995-11-17
Abstract: PROBLEM TO BE SOLVED: To prevent a road surface from being damaged by a tire, make the tire give high anti-skid performance in a snow-covered road or a frozen road, and manufacture the tire easily. SOLUTION: A belt-like anti-skid member 10 consisting of a synthetic resin is buried in a tread 2 of a tire 1 in such a manner that it extends along the circumferential direction of the tire 1. The anti-skid member 10 is provided with a slender, belt-like base part 11 and a great many of pectinate projections 12 projecting almost vertically from both sides of the base part 11. The respective projections 12 extend along the direction almost perpendicular to the ground touch surface of the tread 2, and their tip ends are projected a little from the ground touch surface of the tread 2. Since the projections 12 pierce into the snow-covered road or ice-frozen road, high anti-skid performance is given when the tire 1 runs on such a road. Since the anti-skid member 10 is made of a synthetic resin, it scarcely cause damage to an ordinary asphalted road surface.
