Title: Measurement of interference film thickness
Inventor: INOUE KATSU
IPC: G01B11/06
Filed: 1985-12-06
Abstract: PURPOSE:To enable accurate and rapid detection of film thickness of a thin film of a short optical distance, by evaluating coincidence of a trial interference figure and that obtained by a film interference beam of light and assuming an optical path difference of the maximum coincidence as the optical distance of a specimen film. CONSTITUTION:A light flux provided with an optical distance difference d reflected by a material 8 subjected to measurement is converged into a parallel light flux 9 and irradiated into a polarized light interference meter 30 and interference is generated. When an auxiliary maximum light path distance (d) is above the specified value, for instance, 3mu, then a transparent film 82 is thick enough, eliminating necessity of calculation of the coincidence of the initial interference figure. Mean coefficient of reflection R, coefficient of interference k are obtained and they are stored in a register 24 together with an integer (m) representing d=mDELTAX for arithmetic operations applying composer 25 and subtractor 26. Later, (m) is shown for its film thickness (t) from t=m.(DELTAx/2n)=c.m using the known film coefficient of retraction (n), extraction distance DELTAx for display of the film thickness (t) on a display 28 through the use of a multiplier 27. On the other hand when (d) is equal to the specified value and less, continuous calculations are made beginning with m=1 for determining an integer assuming the smallest value of accumulated value E of errors.

Title: Developing agent supplying device
Inventor: TAKAHASHI TOMOHIKO
IPC: G03G15/08
Filed: 1984-12-28
Abstract: PURPOSE:To obtain a developing agent supplying device which does not scatter a developing agent, by automatically opening and closing the developing agent discharging port of the device in accordance with the mounting and removing operation of a developing agent carrying member. CONSTITUTION:When a toner cartridge 22 is placed on the toner carrying sec tion at the part 23 of a printer main body, on which the toner cartridge 22 is to be mounted, a pushing-up member 47 provided at the central part of the mounting port 46 of the toner carrying section under a projected condition contacts the lower surface of a toner carrying member 34 and pushes up the toner carrying member 34 against acoil spring 35. As a result, a toner discharg ing port 33 is opened and the toner in the cartridge 22 is carried to the toner carrying section. Since the lower end face of the toner carrying member 34 is in pressure-contact with the inner edge section of the toner discharging port 33 and obstructs the discharge of the toner T by closing the toner discharging port 33 under a condition where the toner cartridge 22 is removed, the toner does not scatter to the outside even if the toner carrying member 34 rotates.

IPC: G06F1/16
Filed: 1995-10-24
Abstract: PROBLEM TO BE SOLVED: To store a mounting object even in a small space in a simple constitution by locating a sheet member stuck between a device main body and the side edge of a cover member that is adjacent to a spindle at a position between the mounting object and the cover member when this member is closed. SOLUTION: A cover member 3 of a mounting object loading mechanism 1 that is placed at the center part of a handy terminal 2 of a portable radio unit, for example, can turn against the device main body with its single side edge 3c defined as a spindle. A sheet stay (sheet member) 4 made of polyester film covers both side edges 3a and 3b of the member 3 through the sticking part of the device main body. Then a memory card is loaded into a mounting object store part 5 through the opening part of the opened member 3. When the member 3 is pushed down, the sheet stays 4a and 4b are gradually folded in two and stored. Thus the stays 4a and 4b can be stored in an extremely small store space, and the mechanism 1 can also be stored in a simple and small area.

Filed: 1998-09-29
Abstract: PROBLEM TO BE SOLVED: To enhance a workability such as parts-mounting by attaching a cap for temporarily tacking a bolt by engaging with a tool to a bolt head portion when the tool is inserted to a tool hole. SOLUTION: When an end portion 18a of a hexagonal wrench 18 is inserted to a hole 19a of a head portion 19 of a bolt 16, a cap 21 for temporarily retaining the bolt 16 to the hexagonal wrench 18 by engaging with the wrench 18 is used. The cap 21 is made of a resin and comprises a cylindrical fitting potion 21a for fitting with an outer surface of the head portion 19 and six engaging pieces 21b formed by bending to a center side of the front end opening. A tip end 21c of the engaging pieces 21 has a slightly smaller diameter than an outer diameter of the end portion 18a as a whole and is certainly engaged with the end portion 18a. Thereby, even if a screw hole is downwardly directed and is at a deep potion, the bolt 16 does not fall off from the hexagonal wrench 18 and a parts-mounting work can easily be carried out.  Since it is not required that the bolt is supported by a hand and the bolt is previously temporarily fastened in a screw hole, a workability can be enhanced.

CONSTITUTION:A main pattern portion 3 containing marks 1 and 2 for dimension measurement is surrounded by an outer frame member 4 and has a drawing area rate of 70%. The mark 1 for dimension measurement is located near the outer frame member 4 and surrounded on two sides by this member 4, while the mark 2 for dimension measurement is located near the center of the main pattern portion 3 and separated from the outer frame member 4. A pattern member 5 for compensating a 'blushing effect' draws a pattern at a drawing area rate of 80%. According to this constitution, the dimensional difference between the mark 1 for dimension measurement and the mark 2 for dimension measurement is held down to 0.12mu. If the drawing area rate of a main pattern and that of the outer frame member are within + or -30% approximately, a shift in dimensions due to the 'blushing effect' can be reduced sufficiently.
