Title: Scroll fluid machine
Inventor: TSUNODA MASAYUKI
IPC: F04C18/02
Filed: 1989-06-07
Abstract: PURPOSE:To make it possible to improve the degree of freedom of internal volume and cylinder volume in spite of dimensional restriction by forming a scroll body having pitch varying according to the involute angle of scroll. CONSTITUTION:In a swing scroll 11, a scroll pitch that is the distance between the center lines of a scroll wall 21 is set so as to become smaller (P1>P2) as the scroll extends outside. In addition, the thickness of the scroll wall 21 is also set so as to become smaller like the scroll pitch. By the swing scroll 11 thus constituted and fixed scroll, a swing scroll is operated making a plurality of seal points bring into contact with the fixed scroll simultaneously. In this case, the confinement volume of the most internal periphery becomes larger than that in the case of using a scroll wall having the same outline and a fixed pitch. By this, a scroll body which realizes the volume variation adapting cylinder volume and internal volume rate to object and use can be obtained. Therefore, the degree of freedom of design can be improved in spite of dimensional restriction.

Title: Method and device for recognizing dial pulse signal
Inventor: HIROKAWA TOMOHISA
IPC: H04Q1/32
Filed: 1993-06-17
Abstract: PURPOSE:To acquire a stable recognition result by counting the number of pulses for make time and brake time. CONSTITUTION:When a signal is inputted to an input terminal 1, the signal passes through a high pass filter for cutting off low frequency noise by a signal shape section 2 and the signal is converted into a power value series at every short time and written sequentially in a ring buffer 3 having a capacity equal to or more than a maximum time length per one dialing. The written value is referred to measure line noise. The point of time when the short time power value in the buffer 3 exceeds four times the line noise is defined as a start point of a dial pulse signal and when frames whose short time power value is less than the T are consecutive for 30 frames or more, it is regarded as an end point of the dial pulse signal and written in the signal buffer. A time characteristic detection section 7 performs detection processing of make time and brake time for the written dial pulse signal. Since the number of pulses existing in the make time and the brake time is counted by taking the make time and the brake time into account, the dial pulse signal is stably recognized.

Abstract: PURPOSE:To improve the degradation of efficiency due to the short diffusing distance of free carriers which are peculier in an amorphous semiconductor by generating an internal electric fiedl in a nondoped layer in the photovoltaic device wherein an amorphous semiconductor is used. CONSTITUTION:An amorphous semiconductor layer 3 comprises a P type layer 3a with a thickness of 40-1,000Angstrom , a nondoped layer 3b with a thickness of 0.5-2mum and an N type layer 3c with a thickness of 200-1,000Angstrom . In said device, when light enters the amorphous semiconductor layer 3 through a substrate 1 and a first electrode 2, free state electrons and holes are generated in said layer and collected by first and second electrodes 2 and 4, and an electromotive voltage is generated. At this time, the internal electric field is generated in the nondoped layer 3b of the amorphous semiconductor layer 3 so as to expedite the movement of the electrons and holes generated by the irradiation of the light to the first and second electrodes 2 and 4. That is, with respect to the energy band of the nondoped layer 3b, the composition ratio of each layer is controlled so that the width of the optical forbidden band becomes gradually small from the side of the P type layer 3a to the side of the N type layer 3c. Therefore, the electric field generated in the nondoped layer 3b expedites the movement of the free carriers to the first and second electrodes 2 and 4, and the disappearance of the free carreiers in the nondoped layer 3b is prevented.

CONSTITUTION:In the case of executing a data communication by connecting a terminal side and the center side by a subscriber telephone line, first of all, a terminal side MODEM 1 calls a center side MODEM 2 and a line is connected.

Title: Leak position detection for liquid transporting pipeline
Inventor: KOSUGI SANAI
IPC: G01M3/04
Filed: 1982-08-23
Abstract: PURPOSE:To enable accurate detection of a very limited leak by comparing an etimated value of the pressure at a certain time at a certain measuring point in a liquid transporting pipeline with an actual measured value at a certain time after the pressure is estimated from measured values on the immediate upstream and downstream from the measuring point. CONSTITUTION:Liquid pressures are measured at a very small sampling time interval. A pressure at the time (t) at a certain point P0 when no leak exists is calculated based on the measured pressure value obtained at the time t-DELTAx1/a (a: sound velocity in a liquid pipeline 1) at the measuring point P1 on the immediate upstream separated by DELTAx1 from the measuring point P0 and the measured pressure value obtained at the time t-DELTAx2/a at the measuring point P2 on the immediate downstream separated by DELTAx2 from the point P0 to determine an estimated value. The estimated value thus obtained is compared with the measured vaue of an actual pressure at the time (t) at the point P0 to detect leak. When leaks are detected at the adjacent measuring points P0 and P1, the distance (l) from the point P0 to the leak point is calculated by the formula putting the detection times at t1 and t2 to detect the leak position.

Abstract: PURPOSE:To attain efficient picture compression by outputting a specific code from a specific code register in place of an MH code for one line's share stored in a buffer memory when the level of picture data of one line is all white or black level. CONSTITUTION:When the level of a picture signal of one line is all at a white level at the transmission side, a specific code from a specific code register 313 is outputted in place of the modified Haffman MH code for one line's share stored in a buffer memory 303. For example, in order to indicate the 3360 picture elements of the short side of an A4 size sheet as the fully white level, the MH code of a code length 29 is required and the compression efficiency is brought into 1/2 or over with respect to one line by replacing the code into a code of a code length 8. On the other hand, when the MH code of white run 0 is received at the reception side, it is recognized that the said line is at a fully white level and when a printer is used, for example, it is controlled to apply paper feeding without recording anything on one line.
