Title: Density measuring method
Inventor: MATSUI MASAMI
IPC: G01N9/00
Filed: 1991-02-13
Abstract: PURPOSE:To measure the density of a irregular-shaped material. CONSTITUTION:A sample S is stored in a sample container 3 with a known inner capacity, measurement gas is filled, the measurement gas in the sample container 3 is discharged into a gas detector 7 by carrier gas, and the signal from the gas detector 7 is integrated and converted into the volume of the vacant space of the sample container 3. The quotient of the mass of the sample S divided by the difference between the volume of the sample container 3 and the vacant space of the sample container 3 is obtained. The measurement gas filled in the sample container 3 containing the sample S is discharged into the gas detector 7 by the carrier gas, the integration value of the output is obtained, thus the volume of the vacant space of the sample container 3 can be known. Even if the sample S, sample container 3 and gas do not attain the temperature equilibrium state in the process, the quantity of the gas to be measured is not changed, and the volume of the vacant space of the sample container 3, i.e., the volume of the sample S, can be correctly measured without waiting for the temperature equilibrium.

Filed: 1999-02-19
Abstract: PROBLEM TO BE SOLVED: To obtain an innovative cover-opening/closing mechanism which enables an opening/closing cover to be opened/closed at 180 deg. and to be temporary fixed at an optional angle equal to or smaller than 180 deg. by connecting the opening/closing cover to a first hinge provided on a connecting member and connecting an exterior cover to a second hinge provided on the connecting member. SOLUTION: When an opening/closing cover 2 provided in a part of an exterior cover 1 is rotated due to operation, maintenance, consumed-item replacement, etc., the opening/closing cover 2 disposed in an inside position that is invisible outwardly and a first hinge 3a provided on a connection member 3 rotate. After the first hinge 3a rotates to a possible rotation angle, a second hinge 3b provided on the exterior cover 1 and connecting member 3 rotates, so that the opening cover 2 can be rotated 180 deg.. This eliminates such problems as degradation in operability due to insufficient opening/closing angle of the opening/closing cover 2 and damage to the cover. Also, such a structure can solve such problem that its outer appearance is spoiled.

Abstract: PURPOSE:To prevent data from being omitted by enabling high-speed communication even in a state that any beat signal is not detected or can not be detected. CONSTITUTION:At the time of communication start or the like, the data are transmitted while confirming coherent detection conditions on the optical reception side and when any beat signal is not detected as the detection conditions, for example, the transmission of data signals is controlled to continuation, stop or retransmission by a control circuit 26 while transmitting that information from an electronic shutter 50 to a light receiving element 25 on the optical transmission side. Therefore, even when no beat signal is detected, the omission of data is eliminated at the time of detecting no beat signal by retransmitting the same data signals. At such a time, since a wavelength tuning part controls the wavelength of second coherent light to a local oscillation LD 30 so that the wavelength can be tuned based on the detection condition information, when the wavelength tuning is deviated. the wavelength can be easily tuned and the data can be communicated at much higher speed.

Title: Preset counter device
Inventor: MURATA TOMOJI
IPC: G03G21/02
Filed: 1979-04-06
Abstract: PURPOSE:To make unnecessary the re-setting of the preset counter when copying a single sheet after resetting, by setting the content of preset counter of copying machine automatically to 1 when reset. CONSTITUTION:When the number of copies is set in a preset counter 14 which counts up and down through a count-up switch 16, the set number of the counter 13 decreases, whenever one copy is made, depending on the closing signal of a count-down switch 20 which cooperates with the movement of the original platen. When copying of the set number is finished or the counter 13 is reset through a reset switch 15, the counting content of the counter 13 becomes zero, and the display on an indicator 14 becomes also zero. This zero display output inverts the output inverts the output of a NAND gate 6 through inverters 9-12. As a result, 1 is set in the counter 13. Therefore, after resetting the copying machine, one copy may be made, when copying of the specified number is finished, without having to set the preset counter again.
