Title: Electromagnetic flowmeter for molten metal
Inventor: KIN TOJI
IPC: G01F1/58
Filed: 1986-12-03
Abstract: PURPOSE:To prevent a duct from bursting owing to abrupt temperature variation by providing a support means which supports a port movably according to variation in the length of the duct due to thermal expansion. CONSTITUTION:When molten metal 2 flows in the duct 5, the temperature of the duct 5 rises and the length of the duct 5 increases owing to its heat expansion. The duct 5 presses the port 3 and a rounder 4 lengthwise as the length of the duct 5 increases. The rounder 4 is fixed on the floor surface, but the port 3 is movable, so the port moves as shown by an arrow A with the pressing force of the duct 5, so that the variation in the length of the duct 5 is absorbed. Consequently, the duct 5 is allowed to expand and contract freely and is prevented from bursting owing to its length variation due to abrupt temperature variation.

Title: Assay medicine for antitumor effect of host intervening anticancer agent
Inventor: TAKATSUKI FUMIHIKO
IPC: G01N33/15
Filed: 1991-10-31
Abstract: PURPOSE:To make it possible to monitor whether antitumor effect can be expected or not in a clinical way when host intervening anticancer agent is used for a patient by containing lentinan or Sonifiran. CONSTITUTION:This assay medicine contains lentinan or Sonifiran. When the lentinan as the amount of anticancer agent is administered, blood-vessel permeability rises up. Then, the macrophage in the organism is activated by the administering of the lentinan, and the second path of the complement is also activated. The complicated biological reaction caused by various freed mediators occurs. As a result, the blood-vessel peremeability is changed. It is estimated that the occurrence of the reaction such as this at the local tumor position is related to the apperance of the antitumor effect. Therefore, the antitumor effect can be judged by inspecting the change in reaction in tumor sample, which is obtained by surgically extracting the same reaction and the change in intracutaneous reaction of patient.

Title: Electrode control system for dc butt welding machine
Inventor: HASEGAWA KAZUYOSHI
IPC: B23K11/24
Filed: 1990-10-24
Abstract: PURPOSE:To improve the working rate of a production line by comparing the displacement quantity of the initial interval between electrodes due to wear with a reference value of the interval between electrodes corresponding to the preset electrode exchange time, producing an output signal when the displacement quantity exceeds the above- mentioned reference value and determining the exchange time of the electrode. CONSTITUTION:The rim material end faces are pressed by the specified pressure. This position when pressed, in other words, the interval between the electrodes where welding is started by the initial pressurizing force is advanced excessively by the interval if the butt interval of the rim materials is widened and afterward, this is stopped at the positions where the end faces are brought into contact with each other. At this stopped position, the displacement quantity of the interval between electrodes is read out. Namely, the electrode exchange time can be known from variance of butt accuracy due to wear of the actual electrodes by comparing the displacement quantity of the initial interval between electrodes with the reference value corresponding to limitation of use of the electrodes. Consequently, the real electrode exchange time is determined automatically and the service life of the electrodes can be known effectively and the working rate is improved.

Filed: 1987-11-13
Abstract: PURPOSE:To obtain a one-time program EP-ROM which a user can easily use by using a redundant memory area after the program is assembled to a package and inspecting writing characteristics on the user side. CONSTITUTION:When a defective exists in a memory area 1, writing is carried out to a floating gate MOSFET 17 corresponding to the row address of the defective, a test signal TE is used as an 'H' and then, a redundant memory area 2 is used as the ordinary memory. In such a case, the memory area 2 cannot be used as the inspection of the writing characteristics. On the other hand, when the defective does not exist in the memory area 1, the memory area 2 can be used for the inspection. That is, the arbitrary row address is designated, and the writing is carried out to a FET 17 corresponding to the row address. Further, the memory area 2 is selected with the signal TE as the 'H' and the characteristics are inspected. Thus, the one-time program EP-ROM which is easily used is obtained.

Title: Rack and pinion position detecting equipment
Inventor: TANAKA SHUICHI
IPC: G01B21/00
Filed: 1992-10-05
Abstract: PURPOSE:To sustain a constant distance between the rotary shaft of a pinion and a rack at all times. CONSTITUTION:A rack 1 has teeth in one direction and fixed at a position along the moving path of a body to be positioned independently therefrom. A pinion 2 meshes the teeth of the rack 1 and moves relatively thereto and rotates. Rotational position detectors 9, 10 mounted on the rotary shaft of the pinion 2 detect the rotational position thereof. A load stabilizing means stabilizes the load being applied substantially normally to the moving direction at a constant level between the pinion 2 and the rack 1. Since the load being applied in vertical direction is kept constant between the pinion 2 and the rack 1, constant distance can be kept at all times between the rotary shaft of the pinion 2 and the rack 1 even if the fixing part of the rack 1 is distorted or the body to be positioned fluctuates in the direction substantially normal to the moving direction. This constitution protects the rotary shaft against damage and detects the moving position of the body to be moved with high accuracy.
