Title: Detecting circuit for peak
Inventor: KAWAI RIYUUICHIROU
IPC: G01R19/04
Filed: 1990-11-15
Abstract: PURPOSE:To carry out stable peak detecting operation at a high speed by allowing a current having the same intensity as the current flowing to the second current supply circuit to flow out of a detecting transistor. CONSTITUTION:In a charging mode wherein a large current flows to a detecting transistor, a large current is supplied to the detecting transistor 1 from the first current supply circuit 3 and a peak voltage holding circuit 2 is charged at a high speed. In a holding mode, the active state of the detecting transistor 1 is held by allowing an idle current of a minute current value to continuously flow from the second current supply circuit 4. By this method, it can be prevented that a charge current flows to the peak voltage holding circuit 2 when charge voltage approaches an objective value and, since the active state of the detecting transistor 1 can be held, stable peak detecting operation can be obtained with respect to a signal different in pulse width or a signal changing in potential at high speed.

Title: Scroll fluid machine
Inventor: SHIRAI ATSUO
IPC: F04C18/02
Filed: 1989-11-30
Abstract: PURPOSE:To improve durability, compression efficiency and the like by setting an average clearance to be small in the spiral position from a lap center end to nearly 3pi, in a device in which a chip seal is fitted into the sealing groove of the lap end surface opposing to a scroll sliding surface. CONSTITUTION:Respective laps of both fixing/turning scrolls not shown in a figure, are arranged while being shifted in phases at 180 deg. (1pi) from each other. The turning scroll revolves, namely, it is moved by 2pi, while respective laps being in brought in natural contact. As a result, differential pressure between the outer circumference side and the inner circumference side, of a chip seal 1 fitted into a sealing groove 2 becomes largest in a range from a lap center end to 3pi. In this case, an average clearance 3A in a spiral position from the lap center end to nearly 3pi, is set smaller than the clearance 3B of a spiral part on this outer circumference side. It is thus possible to improve durability and compression efficiency without bringing abrasion of the chip seal 1 and reduction of sealing property.

Abstract: PURPOSE:To prevent contamination with foreign matter, splashing, and sudden changes in composition and temp. and to obtain a thin metallic film having uniform composition and film thickness by supplying a vapor deposition material through an inlet tube inserted into a molten metal in an evaporation crucible. CONSTITUTION:For example, a molten metal 12 composed of a vapor deposition material (consisting of a Co-Cr alloy in which the vapor pressure of Co is lower than the vapor pressure of Cr) heated and melted by means of an electron gun 11 is put into an evaporation crucible 10 made of magnesia. A supply rod 14 in which Cr content is higher than that in the molten metal 12 is supplied into the molten metal 12 through an inlet tube 13 inserted into the position under the surface of this molten metal 12. As a result, although foreign matter 15, such as oxide which is lighter than the molten metal 12, introduced at the time of the supply of the rod 14 floats on the surface of the molten metal 12 this surface is separated from the molten metal surface in the evaporation region concerned with vapor deposition and the above foreign matter 15 can be prevented from flowing into the evaporation region. Further, since the inlet tube 13 is inserted into the position under the surface of the molten metal 12 in the crucible 10, a Cr-enriched molten metal eluted from the rod 14 is diffused from the bottom of the molten metal 12 and gradually supplied toward the surface of the molten metal 12.
