Title: Mixing device of high temperature gas and cooling water
Inventor: SUZUKI MASAMI
IPC: F16L53/00
Filed: 1998-01-07
Abstract: PROBLEM TO BE SOLVED: To reduce a water pressure change even when a cooling water flow rate is changed, and to always efficiently cool exhaust gas by arranging a cooling water chamber to surround an exhaust pipe on the outer periphery of the outlet end part of the exhaust pipe, and arranging ring-shaped clearance in contact with the exhaust pipe to a cooling water chamber partitioning wall inner end of the end surface side of the exhaust pipe. SOLUTION: Cooling water 6 filled in a cooling water chamber 2 from a cooling water inlet pipe 5 is injected as a cylindrical water screen into an expanding chamber 7 to expand exhaust gas by passing through ring-shaped clearance 4 arranged in contact with an exhaust pipe 1 on the inside end of an elastic partition wall 3 on the end surface side of an exhaust pipe 1. In this case, water 6 is blown off while turning toward the center of a flow of the exhaust gas 8 by generating turning motion since the cooling water inlet pipe 5 is arranged in the tangent direction in the cooling water chamber 2. At this time, the ring-shaped clearance 4 expands since an outer peripheral edge-fixed elastic partition wall 3 is deformed on the inside diameter side by a much water quantity, so that a large quantity of cooling water flows in the expanding chamber 7 to effectively cool the exhaust gas 8.

Title: Method for detecting breaking position of test piece in tensile strength test
Inventor: SASAKI TATSUYA
IPC: G01N3/06
Filed: 1995-02-22
Abstract: PURPOSE: To detect the position of a break in a short time without deteriorating the detecting accuracy for the position while saving the space and reducing costs in a tensile strength tester. CONSTITUTION: Laser beams are emitted from a projecting part 3c of a width- measuring device 3 and detected by a photodetecting part 3d. The laser beams are scanned in a widthwise direction of a test piece 1 and at the same time, the scanning position is shifted. An upper broken piece when the test piece 1 is broken is raised. The position of an edge of a lower broken piece in the widthwise direction is detected at a measuring position on a boundary of a detection section by the width-measuring device 3. Only the presence/absence of a broken piece is detected between the boundaries by the width-measuring device 3. If there is no broken piece, the position of a break is detected from a positional relation between the current scanning position and the detection section.  Further, a positional relation between a crack line of the broken piece and the scanning position is detected from the detected position of the edge and a center position in the widthwise direction, so that the position of the break is detected from a positional relation between the detecting result and detection section.

Title: Light applying measuring instrument
Inventor: IDA YOSHIAKI
IPC: G01J4/04
Filed: 1985-02-21
Abstract: PURPOSE:To obtain an instrument enabling to perform accurate measurement even if the ambient temperature is changed by inserting an element having double refractivity into an optical sensor part. CONSTITUTION:The emission wavelength of light from an optical transmitter 1 is changed by its ambient temperature and the light intensity modulation is made by the quantity to be measured by a polarizer 4, a Faraday element 5 and an analyzer 6 constituting the optical sensor part but since a Verdet's constant of the Faraday element 5 has wavelength dependency, the modulation sensitivity is changed by the temperature of the transmitter 1. Then, since the modulation sensitivity at the optical sensor part is always constant even if the wavelength of the transmitter 1 is changed by providing the double refractivity element 15 having the wavelength dependency contrary to said wavelength dependency, the accurate measurement is made possible. Since the light of linear polarization from the polarizer 4 is divided into a component for an angle of its plane of polarization and a component rectangular to the plane of polarization by inserting the element 15, the component rectangular to the parallel face works so as to lower the modulation sensitivity and the wavelength dependency can be canceled freely by selecting properly a relative angle of the plane of polarization of the polarizer 4 with the analyzer 6.

Abstract: PURPOSE:To measure a distance with high accuracy by latching the counted value of a counter every time an envelope detecting circuit generates an output and regarding a counter counted value which is latched right before that action as the reception time of a reflection wave with the output of a period detecting circuit. CONSTITUTION:A signal received by an antenna 1 is inputted to both the envelope detecting circuit 4 and a synchronous detecting circuit 6. The signal detected by the circuit 4 is detected by a comparing circuit 5 and a latch circuit 13 receives a latch signal 5a at this point of time. The circuit 13 latches the counted value of a counter 11 every time the signal 5a is received. The signal inputted to the circuit 6, on the other hand, is passed through a low-pass filter 7, shaped 8 with respect to waveform, and sent out as a latch signal 8a to a latch circuit 14. At this time, there is no influence exerted by a noise because of synchronous detection, but the signal 8a is delayed slightly behind the arrival time of a received radio wave because of delay characteristics of the filter 7. For the purpose, a counted value corresponding to the arrival time of the received radio wave latched by the circuit 13 is transferred to the circuit 14 and an arithmetic display pat 15 calculates and displays the distance to an object of measurement.

Abstract: PURPOSE:To eliminate the need for a color filter, to shorten a reading time and to easily set a threshold by defining a light source for projecting light on multicolor characters or pictures to be the plural light sources different in a light emitting spectrum intensity distribution. CONSTITUTION:A first and a second lights 41, 42 are projected on a white board 43 from a first and a second light sources 39, 40, reflected by the picture 7 and the synthesized reflected light of a color opposite to the picture 7 is made incident on a photoelectric converting part 29. At this time, when the wavelength of the lights 41, 42 are defined to be the lights low and high in the light emitting spectrum intensity respectively by considering about 450mm as a boundary, a large difference is generated between the electric signals of the respective colors. For instance, since the reflectance of a blue marker is different from the reflectance of a black marker when the wavelength of the light is below about 450mm, a large difference is generated between the output values of the electric signals of the respective colors to easily take the threshold. The light emitting intensity of the light sources 39, 40 is adjusted to cope with the reading of various kinds of colors.
