Abstract: PROBLEM TO BE SOLVED: To provide a tubular structure, a cap and a developing roller, securing a sufficient press-in force, and easy to disassemble. SOLUTION: In a tubular structure wherein a cap 4 is pressed and fixed in an inner circumference end part of a sleeve 2, the cap 4 has a tapered outer circumference, while the sleeve 2 is formed with a spigot part 2b at the end part. A length of the spigot part 2b is set to a longer value than a maximum value of a length L of a press-in part A of the cap 4. The press-in part A of the cap 4 has a nearly cylindrical shape with on brim. An end face 2c of the sleeve 2 and an outer end face 4k of the cap 4 are disposed in one plane. Thereby, after the press-in of the cap 4 into the inner circumference end part of the sleeve 2, a pressure of a maximum diameter part of the cap 4 to the sleeve 2 can be enlarged so that an elastic force toward a radial directional outside, i.e., an elastic force toward an inner circumferential face of the sleeve 2, can be enlarged.

Title: Electric micrometer
Inventor: MIYAJI KATSUFUMI
IPC: G01B7/02
Filed: 1996-09-27
Abstract: PROBLEM TO BE SOLVED: To measure a size highly accurately by turning two sine wave voltage signals to the same phase by a pasha shift means and adding the signals. SOLUTION: When two sine wave voltage signals S1 , S2 are input, a fixed phase shifter 1 changes a phase of the input signal S1 to a fixed value, e.g. 90 deg. delay. Supporting that the input signals S2 is delayed by 5 deg. to the input signal S1 , a phase difference detection circuit 3 detects a phase difference of the input signals S1 and S2 , and outputs a phase shift signal S3 corresponding to the phase difference. A variable phase shifter 2 changes a phase of the input signal S2 by a value determined by the phase shift signal S3 . For instance, when the input signal S2 is delayed by 5 deg. to the signal S1 , the variable phase shifter 2 delays the input signal S2 by 85 deg.. Therefore, a phase difference is not present between an output signal S4 of the fixed phase shifter 1 and an output signal S5 of the variable phase shifter 2.  An adder 4 adds the output signals S4 , S5 thereby to obtain a measurement signals S6 without an amplitude error. Accordingly, a size can be measured highly accurately.

Filed: 1997-09-22
Abstract: PROBLEM TO BE SOLVED: To enable standing observation and sedentary observation at a proper position without changing the set height of a microscope by setting the tilt angle of a tilt lens barrel so that a specified angle is included. SOLUTION: By setting the tilt angle to 30 deg. to 60 deg., the standing up observation and the sedentary observation can be executed at the proper position without changing the height of the microscope. Besides, the operability of the fixed tilt angle is obtained at every position without being affected by gravity. In the case of the sedentary observation, a sample 6 is placed on a mount 5 and positioned near a center. Next, a revolver 12 is turned and the objective lens 13 of low magnification (4×)-(10×) is inserted in an optical path. Then, the angle of the tilt lens barrel 10 is adjusted so as to be looked in at the easy position. Simultaneously, the height of a seat is adjusted by considering the operability of a focusing knob 4.  In the case of the standing observation, almost the same operation as the sedentary observation is executed but only the angle of the lens barrel 10 is adjusted.
