Title: Phase detecting device
Inventor: SHURBOFF CARL L
IPC: H03D13/00
Filed: 1999-03-15
Abstract: PROBLEM TO BE SOLVED: To provide the phase detecting device which provides equivalent electric charges for a loop almost under in-phase conditions. SOLUTION: A phase detector circuit 500 is equipped with a 1st flip-flop 502, a 2nd flip-flop 504, a 1st charge pump 506, and a 2nd charge pump 508. One flip-flop enables the charge pump directly in response to a received time signal. A 1st delay circuit 512 delays the output signal from the 1st flip-flop 502 to an AND gate 510 putting together a delayed output signal and the output signal from the 2nd flip-flop 504. The output of the AND gate is delayed by a 2nd delay circuit 514 to generate a delayed reset signal. This reset signal resets both the flip-flops at the same time to disable the charge pump. The phase detector circuit 500 balances the quantity of electric charges given to the phase-locked loop almost under in-phase conditions to improve the linearlity of the phase detector.

Title: Ultrasonic probe
Inventor: SHIMAKURA SHUNSUKE
IPC: G01N29/04
Filed: 1995-03-27
Abstract: PURPOSE: To provide an ultrasonic probe capable of reducing the attenuation of the ultrasonic wave. CONSTITUTION: A piezoelectric film 2 is arranged on the upper face 1a of an acoustic lens 1, a piezoelectric film 10 is arranged on the lens surface 1b of the acoustic lens 1, and a matching layer 3 is provided on its outside. When the piezoelectric film 2 is excited, the ultrasonic wave is generated, the ultrasonic wave passes through the acoustic lens 1, is focused by the lens surface 1b, and is radiated to a sample not shown in the figure via the piezoelectric film 10, matching layer 3, and water or the like not shown in the figure. The ultrasonic wave reflected from the sample is returned to the piezoelectric film 10 through the original path to excite the piezoelectric film 10, and the electric signal corresponding to the reflected ultrasonic wave is obtained.  Since the reflected ultrasonic wave does not pass through the acoustic lens 1, attenuation is reduced by that much, this ultrasonic probe can be used for obtaining the internal information at the depth of the sample, and it can cope with the use of high frequency.

Title: Cowl grill of automobile and its manufacture
Inventor: SHIMIZU KATSUTAROU
IPC: B60J1/02
Filed: 1993-03-26
Abstract: PURPOSE:To simplify the processes for manufacture and assembly by forming a cowl grille integrally with a seal member. CONSTITUTION:A cowl grille 1 is formed in a shape that its thickness decreases continuously toward the top end and provided with a lip part 1a. Also it is provided with a reinforcement part 1c which is provided with a grille part 1b located between a lower front end of a window glass 2 and a bonnet 3 and a hollow part 4 which is extended to the entire width of the window glass 2 between the lip part 1a and the grille part 1b. The cowl grille 1 is formed by one mold only. Though circulation of molten resin for the lip part 1a becomes poor in forming because the top end of it is made extremely thin in order to secure flexibility, deterioration of circulation of molten resin can be suppressed by forming a reinforcement part 1c of large capacity continuously to the lip part 1a for which circulation of molten resin is poor. Also inert gas is fed under pressure by hollow injection to form the hollow parts 4 and 6.

Title: Paper sheet processor
Inventor: OKITSU TADAKAZU
IPC: G03G15/00
Filed: 1998-03-18
Abstract: PROBLEM TO BE SOLVED: To provide a paper sheet processor that improves space efficiency and simplifies its drive mechanism by feeding stacks of paper sheets from or to an intermediate tray with the use of a drive source originally used in other drive systems and that prevents overload-resulting breakage of the stack feed section constituted of an endless belt and a paper sheet tray secured thereto. SOLUTION: Of a driving path constituting part of a driving force transmission means for transmitting the driving force of a motor 32 to an endless belt, in the driving path that transmits the driving force to only the endless belt, a torque limiter or driving force limiting means 33 is interposed to check the transmission of driving force equating with or exceeding a prescribed value. Even if a paper-sheet-stack feed section made up of the endless belt and a paper sheet tray secured thereto receives such large driving force as used in other drive systems, or if a paper sheet jam restricts the movement of the paper sheet tray, by way of example, the torque limiter 33 checks the transmission of torque not smaller than the prescribed value to the stack feed section to thus prevent the secured point of the endless belt and paper sheet tray from breaking up on receiving an overload.

Title: Output current controlling circuit for field effect transistor
Inventor: YAMANE KAZUO
IPC: H01L33/00
Filed: 1985-04-03
Abstract: PURPOSE:To stabilize the output signal of an FET, by connecting a current source to the source electrode of a field effect transistor (FET) and by flowing the output current corresponding to the current of the current source. CONSTITUTION:Into an input terminal 11 provided at the gate electrode G of an FET 1, an input signal IN is applied, thereby conducting the FET 1. Accordingly, a current determined by the voltage between the gate and source is flowed and thus an output signal OUT corresponding to the input signal IN can be taken out of an output terminal 12 provided at the drain electrode D. If a current source 2 is connected to the source electrode S, it can control the source current Is. Therefore, even if characteristics of the FET 1 or load resistor 3 are varied, a constant output can be always provided by regulating the source current Is.
