Title: Method for measuring thickness of material body
Inventor: HASHIMOTO NOBUO
IPC: G01B17/00
Filed: 1988-08-16
Abstract: PURPOSE:To accurately measure the thickness of a material body, etc., under water with no contact by emitting an ultrasonic wave toward the center of rotation from an ultrasonic transducer every measuring point on a circular arc and receiving reflected waves on the surface and the back surface of a material body to be measured. CONSTITUTION:The ultrasonic waves emitted toward the center O of rotation from the ultrasonic transducer(TD) 1 from every measuring point on the circular arc 5 is propagated under water and reaches the surface of the material body 3 to be measured. It is reflected on the surface and also it is made incident on the inner part of the material body 3, then reflected on the back surface to return to a TD 1. A distance between the TD 1 and the surface of the material body 3 to be measured and a distance between the TD 1 and the back surface of the material body 3 can be obtained from time differences between the point of time when the ultrasonic wave is emitted and the point of time when the ultrasonic wave reflected on the surface of the material body 3 to be measured is received and between the point of time when the ultrasonic wave is emitted and the point of time when the ultrasonic wave reflected on the back surface of the material body 3 to be measured is received respectively. Just by obtaining a distance between the TD 1 and the center of rotation O, the positional coordinates of the intersections of a line combining between TD 1 and the center of rotation O with the surface and the back surface of the material body 3 to be measured can be detected. Therefore, the thickness of the material body 3 to be measured can be operated based on the positional coordinates.

Title: Multiple address communication system
Inventor: SATOU TOMIO
IPC: H04B7/24
Filed: 1983-10-28
Abstract: PURPOSE:To eliminate radio interference and disturbance by allowing a master station device to superimpose continuously a speaker connection signal on a transmitted wave when no modulation signal exists, or intermittently at prescribed periods when the modulation signal is consecutive for a prescribed time or more. CONSTITUTION:The output of a microphone M of the master station device 1 is fed to a voice controller VOK and its output is inputted to a speaker connection signal generator S.O.OSC via a mark timer circuit M.TIM. When no microphone output is detected and the detection is consecutive for a prescribed time or over, the generator S.O.OSC is started intermittently with a prescribed period and its output modulates the transmitted wave of a transmitter TX. A switch SW is provided between a receiver RX and a speaker SP in a slave station receiver 2 and connected to a time counter circuit T.C via a filter FIL detecting the speaker connection signal. The counter T.C makes the switch SW contact while the speaker connection signal is detected and for a prescribed time only after the signal is lost.

IPC: G01N29/00
Filed: 1986-08-28
Abstract: PURPOSE:To eliminate the damage of a material to be inspected due to the irradiation of excessive high energy, by irradiating the surface of the material to be inspected with high energy beam and detecting the diffraction pattern of the reflected beam therefrom to control energy beam. CONSTITUTION:A pulse signal is inputted to a laser beam source 2 from a switching circuit 3 to emit laser beam which is, in turn, allowed to irradiate a material 1 to be inspected, while the amplitude thereof is modulated by a laser modulator 4 to regulate the quantity of beam, to generate ultrasonic waves. At this time, the diffraction pattern of the reflected beam due to the material 1 to be inspected of the laser beam is detected by a pattern detector 5. The output of the pattern detector 5 is inputted to the laser modulator 4 and, when said output is large, the quantity of the laser beam is reduced and, when the output is small, the quantity of laser beam is increased. Ultrasonic waves are detected by an interferometer 6 to inspect a flaw. Since the quantity of laser beam is controlled, the damage of the material to be inspected generated by the excessive irradiation of high output laser beam can be eliminated.

Title: Array waveguide diffraction grating optical multiplexer/ demultiplexer
Inventor: OKAMOTO KATSUNARI
IPC: G02B6/12
Filed: 1995-08-10
Abstract: PROBLEM TO BE SOLVED: To provide an optical multiplexer/demultiplexer used for a wavelength monitoring circuit for monitoring each wavelength of a wavelength multiplexed signal light beam having an unequal channel interval by arranging an input waveguide for monitoring wavelength together with an input waveguide for signal and arranging output waveguides for monitoring wavelength on both sides of the output waveguide. SOLUTION: An input waveguide for monitoring wavelength 21 is set at the same unequal interval as a signal input waveguide 11 and arranged on the position where the input waveguide 11 is lateraly shifted as it is. Since the input waveguide for monitoring wavelength 21 is arranged by being deviated from the center line of a sectorial slab waveguide 14 on the input side, light beams of two diffraction orders are generated. Output waveguides 22, 23 are arranged on somewhat inner side of the position when two diffraction light beams are generated. By successively changing the port of the input waveguide for monitoring wavelength 21 and finding the level ratio of output ratio of output light beams of the output waveguides 22, 23, the characteristic of wavelength discrimination for every channel complied with the input port is obtained.

Inventor: TEI SHIMEI
IPC: F04D29/38
Filed: 1996-08-02
Abstract: PROBLEM TO BE SOLVED: To effectively reduce aerodynamic noise due to blade end vortex in an impeller for a blower. SOLUTION: In an impeller for a blower having plural blades 4, 4,... on the outer periphery of a hub 5, the blade end parts 4c positioned on the outer peripheral side of the blades 4, 4... are provided with a positive pressure side guide part 6 having a circular arc surface shape bulged to the pressure surface 4b side, which is formed along the blade end part 4c. Thus, an air current flowing from the pressure surface 4b through the blade end part 4c to enter the negative pressure surface 4a side flows into the blade end part 4c side along the positive pressure side guide part 6 to restrain a separating phenomenon in the positive pressure side guide part 6 of an air current, whereby even if a blade end vortex S1 is generated on the negative pressure surface 4a side, for example, an induced vortex is not generated on the positive pressure surface 4b side.  Accordingly, by the prevent of occurrence of an induced vortex, on the positive pressure surface 4b side of the blade 4, pressure fluctuation can be restrained as much as possible to prevent the generation of aerodynamic noise.

IPC: B32B27/32
Filed: 1998-07-21
Abstract: PROBLEM TO BE SOLVED: To simultaneously obtain effects of shading and waterpoofing with a sheet and contrive improvement and uniformizing of a shading percentage.
