Title: Anti-breaking construction for heat exchanger
Inventor: SENOO YASUTOSHI
IPC: F22D1/14
Filed: 1990-02-17
Abstract: PURPOSE:To prevent fatigue failure of a heat exchanger element, due particularly to twisting, or a lowering in heat exchange capacity from occurring, by connecting a bypass passage provided with a restriction means, between the vicinity of an inlet port and the vicinity of an outlet port of a heat exchanger element. CONSTITUTION:A heat exchanger element 1 is provided with a bypass passage 20 between the vicinity of an inlet port 3 thereof and the vicinity of an outlet port 4 thereof. The bypass passage 20 is provided with a restriction means 30 for flow control. Propagation of a shock generated when a fluid passing through the element 1 is abruptly stopped by closing a valve is damped by the bypass passage 20 provided as above, so that the shock is prevented from producing a direct effect on the element 1. In a normal heat exchange operation, further, the restriction means 30 ensures that there is little flow of the fluid through the bypass passage 20. Consequently, breakage of the heat exchanger element 1 due to repeated stress and a lowering in heat exchanger capacity are prevented from occurring.

Title: Manufacture of semiconductor device
Inventor: YAO TAKEYUKI
IPC: H01L29/78
Filed: 1990-02-20
Abstract: PURPOSE:To miniaturize the title device and to diminish ON-resistance by making the angle of incidence of a beam to a substrate smaller than the angle of incidence of a beam to the substrate in the implantation of impurities for forming a high-concentration region for making contact with a well region. CONSTITUTION:When the angle between a line connecting the upper end of a right side gate edge and the lower end of a left side gate edge and a substrate 19 surface is theta1 and the angle between a line connecting the upper end of the right side gate edge and the center of a diffusion window surface and the substrate 19 surface is theta2, the angle theta between an ion beam and the substrate 19 surface is smaller than theta1. Therefore, little impurities are implanted into the diffusion window. Also, when the angle theta between the ion beam and the substrate 19 surface is larger than theta1 and smaller than theta2, the ions are implanted only into the left side of the diffusion window. Thus, it is possible to obtain a small-sized vertical MOS transistor with little ON-resistance.

IPC: C23C10/28
Filed: 1981-03-18
Abstract: PURPOSE:To form a uniform surface covering metal layer with an arbitrary composition, by producing a metal layer on a substrate metal material, and irradiating a beam having a controlled high energy density. CONSTITUTION:A metal powder having a prescribed composition is applied on a substrate metal material 1 for example of carbon steel or the like, or metals having a prescribed composition are plated or spray-coated on the material 1, so that a metal coat is formed. Then a high energy density beam 2 such as a laser beam, an electron beam, etc. having a suitable energy density is irradiated, while the beam 2 or the substrate metal material 1 is moved. By this beam scanning, the volume of the metals to be melted is controlled, and the surface covering metal layer and part of the substrate metal 1 with a prescribed thickness are melted, alloyed, and homogenized. Further, by controlling the volume of the metals to be melted and the melting period, elevation of temperature of the surrounding metal is avoided, and controlling heating of the melted part, quenching of the melted part due to the heat conduction to the adjacent metal can be realized.
