Abstract: PURPOSE:To improve ignitionability and prevent explosion by a method wherein at the inner bottom of a disposal container into which garbage is through an ignitor generating heat by microwaves is placed and at least the side or bottom of the container is forced to be inclined toward the ignitor. CONSTITUTION:A disposal container 7a is placed in a main body 1 as a microwave resonator and at the inner bottom of the container 7a an ignitor 16 composed of a sinter of heat resisting inorganic with permeability for the microwaves is placed. The side and bottom of the container 7a are inclined toward the ignitor 16 and the shape of the container is made conical. Thrown garbage 8 is collected toward the ignitor 16 along the inner slope of the conical container 7a.

Title: Method and device for detecting checked rice
Inventor: YAMASHITA TOSHIHIRO
IPC: G01N33/10
Filed: 1997-04-24
Abstract: PROBLEM TO BE SOLVED: To detect the cracking of rice accurately by picking up the image of a grain of rice, which is placed on a plane and is illuminated with light, from a vertical direction, by processing the image, and by inspecting the abruptly changed part of the density distribution in the long and narrow direction of the image or in a direction that is perpendicular to the direction. SOLUTION: A detection device of checked rice has, for example, a light source 2 such as a halogen lamp, an optical fiber 3 that illuminates a sample with light from the light source 2, an image pick-up device 4 that has, for example, a two-dimensional image sensor, and an image-processing device. Then, the image of a grain of rice 1 is picked up by applying light in a direction that is in parallel with a plane from long and narrow direction, and specific image processing is performed. In normal rice, an image density gradually changes from the tip to the end where the light is applied to. On the other hand, in the checked rice, light is reflected on a cracked surface and the image density suddenly changes, thus detecting the cracking in width direction by, for example, the density ratio of an area where an abruptly changed position is inserted.  The cracking in long and narrow direction can also be detected in a similar method. Also, it can also be detected by obliquely applying light to the rice grain 1 within a range of 45 degrees from the long and narrow direction.

Title: Idle speed controlling actuator
Inventor: NISHINOMIYA TORAZO
IPC: F16K31/06
Filed: 1988-05-02
Abstract: PURPOSE:To eliminate an electrically short-circuiting trouble, caused by infiltration of water, by charging a void part between a case calking part and a sheath mold part of a solenoid coil with an applied plastic seal agent. CONSTITUTION:A void part, generated between a sheath mold 10 stored in a case 2 and its opening calking part 2a, is filled with applying plastic seal agent 22. Since the plastic agent 22, applied to this void part, uses a material of the same quality also to the sheath mold 10, the plastic seal agent, when it is hardened via applying and charging processes, is integrally formed with the sheath mold 10. Accordingly, no deterioration is generated with an excellent seal quality even by repetition of cooling and heating and/or by long period use, and water of salt water or the like is surely prevented from infiltrating from between the case opening calking part 2a and the sheath mold 10.

IPC: H04M3/18
Filed: 1989-04-28
Abstract: PURPOSE: To provide an improved protective arrangement for the subscriber line interface circuit(SLIC) by using a resistor element, a voltage clamping means and a triac means. CONSTITUTION: A Zener diode Z2 is located between a chip wire and an earth, and a Zener diode Z3 is located between a ring wire and an earth. Each of them is always turned on, when the voltage difference between the both ends exceeds about 250 volts. When a voltage surge is generated in a chip or a ring wire, the Zener diodes Z2, Z3 respectively are instantaneously clamped to a voltage smaller than 250 volts, until a triac THY1 or a triac THY2 is turned on in order to shunt a surge to an earth. Thus, the Zener diodes Z2, Z3 carries out a protective function for solid state relays S1, S2 which is similar to that carried out by a diode bridge for an SLIC.

Title: Transmission gear
Inventor: MOROTO SHIYUUZOU
IPC: F16H41/30
Filed: 1984-05-28
Abstract: PURPOSE:To enable the oil in a fluid transmissin device to be surely circulated and cooled, by allowing the delivered oil from an oil pump, driven by a relative rotation generated between input and output members of the fluid transmission device, to continually flow circulating in an oil cooler. CONSTITUTION:If an engine brake is applied, an oil pump 17 causes an oil path 2H to generate a negative pressure by decreasing a pump speed smaller than a turbine speed. In this way, oil is allowed to flow into an oil path 2B from an oil path 2A, but here an oil path 2I communicates with an oil path 2D by the negative pressure generated in the oil path 2H while an oil path 2E is checked by a check valve 24a operating by a positive pressure in the oil path 2E and a negative pressure in an oil path 2C. Accordingly, the oil, circulating in an oil path 3 inside a transmission device from the oil path 2H, is allowed to continually flow into an oil cooler 26 through an oil path 2F and a double check valve 25.

Title: Slag thickness measuring probe
Inventor: DANJO KENICHI
IPC: G01F23/24
Filed: 1994-05-23
Abstract: PURPOSE:To clearly discriminate the interface between the air slag even in the case where conductivity of the slag is low by inserting a plurality of conductors whose melting point is higher than that of steel in a protection tube, and using a probe which is short-circuited in the edge exposed from the protection tube by the conductor having a lower melting point than the slag. CONSTITUTION:Two conductors 2 composed of tantalum whose melting point is higher than that of steel are inserted in the inside of a ceramic-made protection tube 1, and the edge exposed from the protection tube 1 is short-circuited by a conductor 3 of aluminium whose melting point is lower than that of slag. When a probe is brought into contact with the surface of the slag from the air, the conductor 3 having a low melting point is dissolved. At this time a clear discrimination of the interface is made possible, because a resistance value measured by the two conductors 2 inserted in the protection tube 1 on the interface between the air and the slag is changed from a very low value of the metal conductor up to a very high value of the melting slag of low conductivity. In addition, the interface between the slag and melting steel can be discriminated by the two conductors 2 whose melting point is higher than that of steel.

A control means 12 determines the most suitable thawing time in response to the result of estimation. A high frequency wave in a frequency band of the high frequency projecting means is fuzzy estimated by a method in which a voltage detected by a tuning means is analogue-digital converted and as an equation of fuzzing estimation for the converted signals, the fuzzy estimation is carried out in response to at least more than two elements of a relative variation of signal in respect to a time, an elapsing time of a signal up to its minimum point, a signal value when a heating is started and a signal value of the minimum point or the like.
