Abstract: PURPOSE:To obtain a diaphragm having good reliability and easy to mount, by pressing the diaphragm to the step part by a pressure introducing port to fix the same. CONSTITUTION:A housing 7 is formed into a pipe-shaped cylindrical structure having large and small inner diameter parts, while a diaphragm 11 has a ring- shaped thick and rigid leg part formed into a reverse recessed shape from the large diameter of the housing 7, and a gauge is mounted to the surface of the central part thereof.

Title: Compensation method for delay in master equipment loopback type synchronizing bus transmission line
Inventor: YUUZA MASAAKI
IPC: H04J3/06
Filed: 1986-04-01
Abstract: PURPOSE:To eliminate the restriction in the transmission speed, the transmission distance and a terminal equipment location or the like by compensating the transmission line delay difference depending on the location of a terminal equipment. CONSTITUTION:A master equipment ME is provided with a delay measurement circuit DM, delay circuits DE1, DE2 are provided to terminal equipments TE1, TE2 and the terminal equipments TE1, TE2 are connected in parallel with buses T,R of the main equipment respectively. The delay measuring circuit DM measures the delay time from the sending of a synchronizing signal to each terminal equipment till a signal is reurned from the said terminal equipment to the main equipment ME. The delay circuits DE1, DE2 retard the start time of the data sending after the confirmation of synchronization by a delay decided based on the measured data obtained by the delay measuring circuit DM. Thus, a prescribed round trip delay is formed independently of the position of the connection of the terminal equipment and the transmission speed/ transmission distance is improved remarkably.

Title: Discrimination of luster effect
Inventor: SUGA SHIGERU
IPC: G01B11/30
Filed: 1983-05-02
Abstract: PURPOSE:To enable the discrimination of luster effect involving appearance, clearness and brightness by projecting a chart scale graphic having two straight line, black and white, in the same shape by a diffusion light to observe the degree of disturbance. CONSTITUTION:Light of a lighting lamp 1 is projected on the surface of a sample 4 transmitted by a diffusion layer 7 of glass, a diffusion layer 8 of a semi-transparent film and a chart scale 9. In the chart scale 9, two adjacent straight lines black and white the same in the width are arranged parallel in either an arithmetic or geometric progression. Thus, the chart acale 9 is projected on the surface of the sample 4 in a nearly complete diffusion light and a diffusion effect allows the whole figure of the scale to be projected evenly on the surface of the sample thoroughly thereby eliminating misrecognition. The scale comprises figures the same both in the length and width thereby getting rid of the problem on direction.

Filed: 1995-03-31
Abstract: PURPOSE: To directly and accurately detect a solar eclipse via the detection of an output signal from each solar sensor by mounting solar sensors to a plurality of planes forming a side wall part and keeping the sensors faced to all surrounding directions. CONSTITUTION: The main body 13A of an earth satellite 13 and a solar battery paddle 14 fitted with a solar battery 15 are jointed to each other via a support 16. Also, the solar battery paddle 14 is rotated on the rotation of a drive motor 17 via the support 16, thereby changing the direction of the battery 15. Furthermore, the support 16 has a side wall part formed out of four planes 31a to 31d, so as to have, for example, square cross section. In addition, two solar battery cells 32a and 32b, for example, acting as solar sensors are fitted to each of the planes 31a to 31d. As a result, an output signal from each of the cells 32a and 32b less than a threshold value means that sunlight is not irradiated to the whole of the cells 32a and 32b. In this case, the occurrence of an eclipse is judged.
