Title: Surging preventing device for turbocompressor
Inventor: MATSUURA YUTARO
IPC: F04D27/02
Filed: 1986-02-21
Abstract: PURPOSE:To control the surge preestimation even if the faculty of a compressor is deteriorated by the use through years by increasing the opening degree of a ventilating valve when the pressure ratio variation rate for the correction flow rate at a certain correction revolution speed which is calculated by a calculator for calculating said pressure ratio variation rate becomes larger than a limit value. CONSTITUTION:Each output of an inlet pressure detector 16, inlet temperature detector 17, discharge pressure detector 11, flow rate detector 12, and a revolution speed detector 18 is input into a calculator 13, and the pressure ratio variation rate at a certain correction revolution speed obtained by a specific equation is calculated. The limit value of the pressure ratio variation rate is memorized into a memory device 14 before hand. The limit value is generally related to the correction revolution speed. The pressure ratio variation rate of a compressor which is outputted from the calculator 13 and the limit value of the memory 14 are compared, and when the pressure ratio variation rate reaches the limit value, a ventilating valve 10 is opened by a ventilating valve controller 15, and the intrusion into a surging region is suppressed. Thus, even if the faculty of a compressor is deteriorated by the user for years, surging can be preestimated with high precision.

Title: Production of valve seat for cylinder head made of cast iron
Inventor: YANAGISAWA TAKASHI
IPC: C21D9/00
Filed: 1981-03-13
Abstract: PURPOSE:To eliminate the need for reworking with virtually no generation of strains after hardening and to permit sufficient hardening with air cooling by using laser beam irradiation in a hardening treatment for the surface of a valve seat for cylinder heads made of cast iron. CONSTITUTION:A hardening surface treatment using laser beam irradiation is applied on the surface 2 of a valve seat against which the suction and discharge valve of a cylinder head 1 collides, whereby a surface-hardened layer is formed, and a valve seat part 3 is constituted. This hardening is accomplished by using, for example, a CO2 laser device 4, disposing the device 4 with inclination to the central axis of the valve port in such a way that the beam 5 thereof is made incident to the seat surface 2 at an optimum angle and rotating this one turn in an arrow direction. The surface 2 irradiated by the beam 5 is quickly heated and the range of the irradiation can be considerably narrowed; therefore, when the beam 5 passes therethrough, the irradiated part is quickly cooled by the thermal diffusion and has extremely high hardness by causing martensite transformation.

Title: Lens formation method
Inventor: ABE HIDEJI
IPC: H01L27/14
Filed: 1993-02-24
Abstract: PURPOSE:To bring the interval between lenses close to zero by processing adjacent swelling matters into the shape of two separate lenses on a flattening film, and swelling them so that the interval between them may be small or practically zero. CONSTITUTION:An organic film 21 small in viscosity is formed by application on the surface of a CCD solid image pickup element 1. This organic film 21 is covered with the layer of a matter which swells when soaked in solution such as casein, gelatin, etc. A photoresist layer 23 is formed in the position, which corresponds to a light receiving part 21, of the layer 22 of the matter swelling in volume. This is made in the shape of a convex by making it reflow at a temperature of 150 deg.C or thereabout. Next, the shape of the lens is transcribed by 1 vs.1 by the reactive ion etching of oxygen gas. Soaking this in aqueous solution containing coloring material in the line of acidic anion makes dye soak into casein or gelatin and swells the matter layer 22 in volume while maintaining the shape of a lens. This way, the interval between adjacent lenses is made zero, whereby the formation of an on-chip microlens is completed.
