Abstract: A hybrid IC substrate has a substrate body and a retaining film which is formed on a surface of the substrate body. The retaining film enables a solution containing a circuit-element-forming material to permeate therethrough and retains the solution on the substrate body. The solution, which is expelled onto the hybrid IC substrate in the form of liquid drops, permeates the above-mentioned retaining film and becomes attached to the surface of the substrate body. Then, the hybrid IC substrate is baked. The retaining film is thus backed off, thereby forming a film of the circuit-element-forming material as a circuit pattern on the substrate body.

Abstract: An inspecting method and device for inspecting an object or objects such as photomasks having a plurality of identical patterns, to detect defects of the patterns, wherein the object is placed such that the patterns lie in the same plane, and an inspection mask having a plurality of translucent apertures is placed such that the inspection mask is adjacent and parallel to the object. The inspection mask and the object are moved relative to each other whereby each aperture is positioned opposite to mutually corresponding portions of the patterns. The object and inspection mask are irradiated with rays of light emitted in a direction substantially normal to the plane of relative movements thereof. The rays of light transmitted through the apertures and the object are converted into electric signals, and the electric signals associated with the corresponding portions of the patterns are compared with each other, prior to obtaining the electric signals of all of the plurality of patterns.

Abstract: Disclosed herein is means for correcting the position of bottom dead center of a slide in a press having a frame, a crankshaft rotatably mounted on the frame, and a slide connected to the crankshaft and movable in a vertical plane, wherein the correlation between the rotational speed of the crankshaft and the bottom dead center position of the slide is determined in one-to-one correspondence. The means comprises a variable speed motor for rotating the crankshaft; a sensor for sensing the position of bottom dead center of the slide; and a control circuit for comparing the signal generated from the sensor which is representative of the bottom dead center position with a signal representative of a preset reference position of bottom dead center of the slide and controlling the speed of the motor to suit the speed representative of the reference position of bottom dead center of the slide.

Abstract: A molded base, for example, a cabinet of a radio receiver, is molded with a synthetic resin and at least one display element made of, for example, a metal, is embedded in the molded base so as to expose one surface of the element. The surface of the display element is then covered with a finish coating to form a substantially uniformly coated layer. The coating on the surface portion of the embedded display element and further at least a portion of the surface of the display element is subjected to mechanical treatment so that the material surface portion is exposed on the display element, whereby the molded base is provided with an aesthetic and decorative display thereon.
