Title: Organic duct expander
Inventor: HIRAO ISAMI
IPC: A61M29/02
Filed: 1991-09-20
Abstract: PURPOSE:To prevent an organic duct expander from crushing flat under external pressure when expanding a strictured part of an organic duct. CONSTITUTION:When an organic duct expander 1, inserted in a strictured part, absorbs moisture and sells to expand the inner and outer diameters of an expansion portion 2, the expander 1 is larger in moisture contact area than a conventional one with a simple lumen because of four lumens 5, and thus shortens time taken for absorption/expansion. Further, due to four props 4 partitioning each lumen 5, sufficient rigidity is maintained against external pressure from the strictured part. Accordingly, the are of each lumen 5 increases without crushing the expansion portion 2 flat, thereby expanding the strictured part for effective drainage, etc.

IPC: F25D17/08
Filed: 1988-09-28
Abstract: PURPOSE:To cool substances to be cooled in a freezing chamber and an ice making chamber in higher speed by a method wherein high-speed cold air is injected into the lower surfaces of the substances to be cooled through cold air nozzles provided in an airflow contracting passage while increasing the pressure of air by the airflow contracting passage. CONSTITUTION:Cold air, discharged by a cold air circulating fan 5, is guided concentrically to the bottom plate 10 of a freezing room by an airflow distributing passage 11 in front of the cold air circulating fan 5.

A plastic scintillator 3 is mounted on an photoelectric multiplier 6 through an optical coupler 5. Then, it so arranged that fluorescene is taken out at the right angle of the incident X rays 1 and the transmission X rays 2 to avoid the multiplier 6 for detecting fluorescence over the optical path of X rays. After an output pulse of the multiplier 6 is amplified with an amplifier 7, the output pulse alone is selected with a pulse height discriminator 8 depending on the X rays of energy as desired to be counted with a counter 9. This enables simultaneous measurement of the intensities of X rays beams with the absorption rates of more than 50% and under 50%.

Title: Interference distortion gauge assembly with optical fiber
Inventor: ALAN MALVERN
IPC: G01B11/16
Filed: 1997-09-08
Abstract: PROBLEM TO BE SOLVED: To provide an assembly which is hardly affected by flash-to-ground, eliminate consuming of energy in its sensor element of the assembly, and elongate its life, by defining optical strength as specific-multiplied frequency of light which is generated from a light beam generator, and by determining direction and size of distortion in the sensor element based on the ratio of the strength. SOLUTION: The gauge assembly has a sensor element 1 in the form of a certain length of single mode optical fiber 4, and both ends 1a, 1b of the sensor element 1 have peak reflection factor less than 10%. The assembly generates a light beam in single vertical mode, and includes a component for transmitting the beam through the inside of the element 1. In the element 1, interference occurs due to reflection between ends 1a, 1b of the optical fiber, and change of the sensor element length due to its distortion alters strength of the reflected light. A reflected light analyzing component establishes optical strength as one time (1f) or two times (2f) of frequency (f) of generated light beam, and size and direction of distortion of the element 1 are determined from light strength ratio 1f:2f.

Title: Automatic steering device
Inventor: NISHIMOTO MITSUHIKO
IPC: B62D113/00
Filed: 1997-09-08
Abstract: PROBLEM TO BE SOLVED: To prevent a variation in the follow-up and convergent capabilities by calculating the ratio of a variation in steering angle relative to a deviation between a target steering angle and a detected steering angle in a specified time period and changing the control gain of a motor current from steering motor according to a comparison result between the ratio of the variation and a specified value. SOLUTION: While a vehicle is running, a gain control part 22 reads a steering angle from an absolute steering angle detector part 21a when a parameter is zero, and the read value is designated as H0 . Next a steering angle deviation ΔH is read from a steering angle deviation calculation part 13, and the parameter is set to one. On the other hand, when the parameter is not zero, the steering angle is read from an absolute steering angle detector part 21a, and the read value is designated as H1 . Next H0 -H1 is calculated, and then (H0 -H1 )/ΔH is calculated. In addition, (H0 -H1 )/ΔH is compared with a specified value and, when (H0 -H1 )/ΔH is less than the specified value, a signal to raise the control gain of a motor current is transmitted to a PID control part 14.  Then a target motor current value is output from the PID control part 14 according to the steering angle deviation ΔH.

Title: Hot air type heater
Inventor: NOGUCHI YOSHIHIRO
IPC: F02G1/055
Filed: 1983-12-23
Abstract: PURPOSE:To raise the reliability of a hot air heater which can be installed at any place without the needs for cost of power by a method in which an air blow fan is driven by a stirling engine to be turned using the heat of a heater as energy source. CONSTITUTION:When a controller 11 is operated to ignite a burner 8, the flame heates up the heating section 2 of a stirling engine 1. After the ignition of the burner 8, rotation forces of arrow direction are given to a flywheel 3 by automatic application of power to a motor 9 for actuation to actuate the engine 1 after the lapse of a given time period so set as to sufficiently heat up the heating section 2. Afterwards, insofar as the heating section 2 is heated, the operation continues and the fan 4 is driven through a belt 5. Since only a short-time actuation of the eingine 1 is sufficient by supply of power to the motor 9, the consumption of battery 10 is small. Also, since the engine is driven after the lapse of a given time period after the ignition of the burner, a highly reliable hot air type heater free of malactuation can be obtained.
