Title: Water-tube boiler
Inventor: YAMAGUCHI MASATAKA
IPC: F22B37/38
Filed: 1987-10-09
Abstract: PURPOSE: To correct pressure control of a boiler and reduce the amount of consumption of a fuel by obtaining a signal from a pressure adjuster to detect the highest vapor pressure in a required vapor pressure corresponding to each process during operation, and outputting a maximum pressure signal to a boiler control section as a target value. CONSTITUTION: A boiler adjuster 30 receives a signal whether or not each process A, B, and C is in operation from each pressure detector 19a, 19b, 19c, and extracts a set vapor pressure of a pressure detector 19 corresponding to each process in the operation, and further it extracts the highest set vapor pressure among the foregoing vapor pressures. For example, when the set vapor pressure in the process A is 6 kg/cm<2> , 4 kg/cm<2> in the process B, 2 kg/cm<2> in the process C, the boiler adjuster 30 extracts 6 kg/cm<2> in the process A as a pressure signal and outputs a pressure signal of 7 kg/cm<2> with slight redundancy. The pressure signal is inputted into a boiler control section as a target value. Based upon this, the amount of consumption at a burner 22 is adjusted to control the vapor pressure.

Title: Measuring instrument of length
Inventor: TASHIRO HIDEO
IPC: G01B11/00
Filed: 1987-10-09
Abstract: PURPOSE:To enable the measurement of length even when a moving object stops, by a method wherein the wavelength of one of two laser beams applied onto the moving object is shifted by an optical frequency shifter and a difference between the shifted wavelength and an output frequency of a frequency tracking unit is taken out. CONSTITUTION:One of two irradiation laser beams 4a and 4b is shifted by a frequency fM by means of an optical frequency shifter 15. A Doppler signal received by a reception optical system 6 and subjected electric conversion by a photodetector 7 on the occasion turns to have a frequency fd' of the formula, wherein mark V denotes a speed of an object, psi the angle of intersection of the beams 4a and 4b and lambda the wavelength of the laser light. In other words, the frequency fd' is a value obtained by adding up a Doppler frequency fd proportional with the speed V and the frequency fM shifted optically, and it is obtained as the frequency fM even when the object 1 stops. Therefore a frequency tracking unit 9 can execute a tracking operation. By taking out the frequency fd by means of a mixer 17 and a low-pass filter 18 and inputting same to a frequency divider 10, accordingly, the length of the moving object 1 can be measured, including the case of zero speed, in the same way as in a conventional length measuring instrument.

Title: Structure of screw head
Inventor: YOSHIZAWA KAZUYOSHI
IPC: B29C45/52
Filed: 1991-10-03
Abstract: PURPOSE:To maintain the stopped state of a non-return ring relative to the rotation of a screw head and thereby prevent sharing forces from occurring on resin in the outer periphery of the non-return ring by forming notched grooves at a plurality of places in the peripheral direction and thus forming projections. CONSTITUTION:When a screw rotates and moves rearward, a screw head 21 rotates together therewith. At this time, a non-return ring 22 moves forward with respect to the screw head 21 and then comes into contact with the rear surface of a cylindrical part 21b. On the end surface of the non-return ring 22, notched grooves 25a-25c are formed at a plurality of places in the direction, as a result, projections 26a-26c are formed. Accordingly, the screw head rotates whereas the non-return ring is maintained in the stopped state. with the result that a sliding surface is defined between the projections and the rear end surfaces of the cylindrical part. In this instance, resin existing in the interstices between the non-return ring 22 and the small diameter part 21c extends through the side of the cylindrical part via the notched grooves. In consequence, the occurrence of resin burning can be prevented.

Filed: 1993-09-21
Abstract: PURPOSE:To provide an optical fiber gyroscope which facilitates wiring of a connection part of an optical fiber on a case and miniaturizes the case with higher workability. CONSTITUTION:In the optical fiber gyroscope made up of optical components such as a first coupler 2, a second coupler 3, a sensing coil 4 employing an SM fiber and a polarization maintaining fiber, a depolarizer 5 and a phase modulator 6, a connection part of the optical components is recoated with a silicone resin, a UV-hardenable resin or the like the same in material as the optical fibers to form a covered connection part 7. The absence of a sleeve at the covered connection part miniaturizes the covered connection part hence requiring no wide area for installation. The bendable covered connection part can be pulled along the sensing coil thereby achieving higher workability. This also makes the setting of the phase modulator inside the sensing coil possible, thereby achieving a miniaturization of the optical fiber gyroscope.
