Title: Fm modulation circuit and fm demodulation circuit
Inventor: MASUDA MASAYUKI
IPC: H04B1/04
Filed: 1999-02-19
Abstract: PROBLEM TO BE SOLVED: To transmit two signals of a sound signal and a sensor signal being a binary signal by modulating them with a single FM modulator. SOLUTION: In this FM modulation circuit, the sound signal and the sensor signal are added with each other and frequency-modulated by the FM-modulator 2. The low level of the sensor signal is modulated to a frequency f1 and the high level of the sensor signal is modulated to a frequency f2. Consequently, in the FM-modulated signal, both the shift frequency from the frequency f1 and the shift frequency from the frequency f2 are made correspond to the level of the sound signal. The signal modulated by the FM-modulator 2 is inputted to a filter 3 and a filter 4. The filter 3 extracts and outputs 2nd higher harmonic components in the output signal of the FM-modulator 2, and the filter 4 extracts and outputs 3rd higher harmonic components in the output signal of the FM- modulator 2. Then, the output signal of the filter 3 and that of the filter 4 are added with each other by an adder 5 and outputted to a transmission line.

Abstract: PURPOSE:To remove the source of noise generation and produce a robot controlling  device for arc welding etc. that can perform highly efficient TIG welding by changing  the arc start system from the high frequency high voltage applying system to touch  start system. CONSTITUTION:In straight line welding from P1 to P2, when an electrode 18 comes to  a position P1-1, an output start signal is transmitted from a control panel 1 to a contant voltage source device 21, and output voltage of the device 21 is applied between  the electrode 18 and a base material 9. At the same time, the electrode 18 is brought  near in the direction of the base material 9 at moving speed V1. When the electrode 18  comes into contact with the base material 9, a current detecting relay 25 is excited  and closes a normally opened contact 26, and performs movement to the next step position P1-3 at speed V2 making the action to move the electrode 18 to a position P1-2 as  a center. Thus, short circuit between the electrode and the base metal is released, and  an arc is generated between them. Then, the electrode 18 under this condition is  moved to the position P1-3. A welding start signal and a welding current setting signal  I1 is transmitted from the control panel 1 to an electric power source for welding 5,  and initial current I1 is let flow between the electrode 18 and base material 9.

IPC: H04N1/393
Filed: 1992-02-27
Abstract: PURPOSE:To attain nice-looking by integrating a reduction rate in respective pages as much as possible when plural pages of information are respectively reduced and recorded on cut paper. CONSTITUTION:Information fetched by an information fetching means 1 is stored in a storing means 2 and its length is detected in an information length detecting means 3. The length of cut paper is detected by a cut paper length detecting means 6 and the first reduction rate is calculated in a first reduction rate calculating means 7 based on the length of information and the length of cup paper. The first reduction rate is supplied to a reduction rate deciding means 8 and, here, the min. reduction rate is detected. Then, the min. reduction rate is compared with the first reduction rate of the respective pages and the first reduction rate is adopted as the reduction rate of the page when the first reduction rate is smaller. When the min. reduction rate is smaller, the min. reduction rate is adopted as the reduction rate of the page. Thus, the reduction rate of fetched information is almost same so that this has an effect on nice- looking.

Title: Automatic measuring apparatus
Inventor: MIYAMOTO KATSUMI
IPC: G01B21/00
Filed: 1980-03-31
Abstract: PURPOSE:To continuously measure the materials with different sizes transferred in sequence by an apparatus wherein matching with the master is carried out automatically prior to starting of continuous measurements and then comparative measurement is performed with respect to the master. CONSTITUTION:On a measuring stage C workpieces 1 with a size A are subsequently intermittently transferred to a measuring position. A position D right above this measuring point serves as a matching position with the master. Nasters 3 with different sizes A, B... are mounted on a rotary disc 2 and the master designated by a command is rotated downward to the position D. A detector 9 is rotated about a central shaft 8 by 180 deg. and lowered toward the measuring stage C so as to measure the workpieces 1 transferred. The shaft 8 is moved upward or downward every time each workpiece 1 is measured, so that a next new workpiece is measured in sequence. When the measurement of the workpieces with a size A is completed,  matching with the master is carried out using a new master with a different size to  allow the measurement of workpieces with a different size in the similar manner.

Title: Semiconductor memory
Inventor: SHINOHARA TATSURO
IPC: H01L27/04
Filed: 1990-02-21
Abstract: PURPOSE:To miniaturize a semiconductor memory by a method wherein the first grooves and the adjacent second trenches are structured to make specific angle so that the trenches may be spaced farther at respective bottom parts of the adjacent trenches so as to cancel the punch-through phenomenon occurring in the step to narrow the trench spaces on the surface part of a semiconductor substrate. CONSTITUTION:The title semiconductor memory is provided with impurity diffused layers 6, 16, dielectric films 7, 17 and self plate electrodes 8, 18. At this time, the first trenches 6, 7, 8 and the second trenches 16, 17, 18 adjacent to the first trenches 6, 7, 8 are structured to make a specific angle so that these trenches are farther at respective bottom parts. In such a structure, the charge in the first capacitance regions 6-8 used for the data storage can restrain the problem of interference between the capacitance regions 6-8 and the second trenches 16-18 raised by the punch-through phenomenon occurring in the trench bottom parts since the spaces between the adjacent second trenches 16-18 are larger than those of the conventional trench capacitor structure. Resultantly, the spaces between the trenches 6-8 and the trenches 16-18 can be narrowed.
