Abstract: PURPOSE:To provide the antibody for sensitively detecting only LECAM1, and to provide the method for measuring the LECAM-1. CONSTITUTION:A male Armenia hamster (6-10 age in week) is immunized with purified rLEC-IgG four times at 5 day intervals, and two day later from the final immunization the lymph node cells of the immunized hamster are taken out from the hamster and subsequently mixed with the myeloma cells (PAI) of a mouse for their cell fusion.

Title: Valve driving device of engine
Inventor: KAWAMURA HIDEO
IPC: F02D13/02
Filed: 1991-08-20
Abstract: PURPOSE:To make valve opening timing accurate by making valve opening and closing force regulatable, and also to prolong a service life of the valve by making the valve come in contact with the valve seat softly. CONSTITUTION:A valve 1 is provided with a rocking body 4 integratedly. Force for opening and closing the valve 1 can be regulated by controlling the magnitude of the force caused by the relationship between the magnetic flux generated by means of a fixed coil 8 and the regulated electric current in the movable conductor wire 6 of the rocking body 4. In such a way, strong force is output in the early stage of the valve motion by controlling the magnitude of the opening and closing force of the valve 1. When the valve 1 is brought into contact with the valve seat, braking force makes the contact of the valve soft. Accordingly, wear of the valve 1 is reduced.

Filed: 1988-09-19
Abstract: PURPOSE:To improve the characteristics and reliability of a coil component by providing a small groove extending in a direction parallel to the mounting face at least in one of the outward faces of a pair of side legs and the outward face of a coupling section. CONSTITUTION:In a magnetic core, a central leg 2 is provided on a mounting face, i.e., at a position slightly higher than the bottom of side legs 1 and formed at a position extending in parallel with the mounting face and slightly separated from the mounting face. A small groove 4 extending in a direction parallel to the mounting face is formed partly on the outward face of a pair of side legs 1. The groove 4 is of a part for receiving the part of a holder. Two magnetic cores are opposed to match the holder components to the groove 4 at the time of the manufacture of a coil component. As a result, the two cores and the holder are secured to largely improve reliability against a vibration, an impact, etc., and to prevent its characteristics from deteriorating. The groove 4 may be formed on the outward face of the coupling section 3 instead of the leg 1, or may also be formed on both the outward faces of the leg 1 and the coupling section 3.

Title: Input/output insulated analog signal transfer device
Inventor: TANAKA RYOZO
IPC: G08C19/00
Filed: 1990-08-30
Abstract: PURPOSE:To obtain an input/output insulated analog signal transfer device of high precision by combining two photocouplers to reduce the temperature variance of an input/output transfer coefficient and determining the input/output transfer coefficient by a ratio of input/output current transform coefficients of two photocouplers. CONSTITUTION:In a two-channel photocoupler 7, an input terminal and output terminals 7e and 7g are connected, and output terminals 7b and 7i are connected, and output terminals 7a and 7f are connected, and terminals 7e and 7b are used as the input terminal side of the whole, and terminals 7c and 7d are used as the output terminal side of the whole. That is, the variance of the input/ output current transform coefficient of a photocoupler due to the change of temperature is cancelled by two photocouplers 7. Since the value of the overall input/output transfer coefficient of the transfer device is determined by a ratio of input/output current transform coefficients of two photocouplers 7, characteristics of two photocouplers 7 are mixed. Thus, an influence of the change of temperature is reduced, and the variance is reduced against the change of the input signal level to obtain the accurate analog signal transfer device.
