Patent JP-H01150339-A (JP)
Title: Semiconductor device
Inventor: NAKAMURA MITSUYOSHI
IPC: H01L23/522
Filed: 1987-12-07
Abstract: PURPOSE:To obtain a semiconductor device having characteristics similar to those so far by a short manufacturing process by forming a semiconductor device having an N-type diffused layer at the lower part of the tip of a field oxide film for preventing short-circuiting between aluminum wirings and an Si substrate. CONSTITUTION:A laid oxide film 2 is formed on an Si substrate 1, a nitride film is formed thereon, and selectively removed with a photoresist pattern 12, thereby forming a nitride film pattern 3. Then, after the pattern 3 and the film 2 are removed, As ions are implanted to form an N<+> type diffusion implanted layer, As is diffused by thermally diffusing thereby to form an N<+> type diffused layer, and an interlayer insulating film 9 is formed. Thereafter, the film 9 is selectively removed with a photoresist, thereby forming a contact hole 9b. When it is normally superposed with a field oxide upon formation of the hole 9b, it is preferable, but if the superposition is displaced, there is a danger of short-circuiting between alumina wirings and the substrate 1. Accordingly, the N-type layer 5b is required. Thus, a semiconductor device having the same characteristics as those of the conventional one can be manufactured.

Patent JP-H01150753-A (JP)
Title: Refrigerator
Inventor: ABE TOSHIRO
IPC: F25B1/04
Filed: 1987-12-08
Abstract: PURPOSE: To prevent a scroll compressor from being damaged due to liquid-state compression in the time of activating the scroll compressor by allowing a normally- closed valve provided in an intermediate compression space at the fixed scroll side to be opened by the internal pressure of the intermediate compression space so as to let off liquid refrigerant to refrigerant piping upstream an accumulator. CONSTITUTION: When a scroll compressor 1 is activated with liquid refrigerant in a compression space 12, the refrigerant is compressed in a liquid state to cause an abnormal increase of pressure in an intermediate compression space 12b having a sealed structure. In due course of time, the pressure inside the intermediate compression space 12b becomes larger than the total of force applied to a valve 16a by a valve- presser spring 16b and pressure inside a refrigerant piping 17, when a normally-closed valve 16 is opened by the total pressure. Due to pressure difference, liquid refrigerant in the intermediate compression space 12b passes through an opening 15 and the refrigerant piping 17, enters refrigerant piping 6a connecting an evaporator 4 and an accumulator 5, and flops to the accumulator 5. As a result, the scroll compressor is smoothly activated without being damaged because pressure inside the intermediate compression space 12b does not exceed the critical pressure and consequently excessive force is not applied to the bearing of the scroll compressor 1 and the like.

Abstract: PURPOSE:To selectively enlarge the observation range of an anterior part without using a movable part, by arranging an optical member having wavelength permselectivity in front of an observation optical system while arranging a reflecting member and two kinds of illumination light sources to the periphery of the optical system. CONSTITUTION:When the switch S5 of a switch box 9 is turned on, the first illumination light source 5 lights to illuminate the face F of an examinee and the beam reflected by an anterior part Ex is forwardly reflected by a mirror 3 and subsequently again reflected by a convex mirror 2 to successively be transmitted through the objective lens 1 and a wavelength permselective mirror 4 to reach an imaging means 7. Since a wide range of the image of the anterior part is projected on a monitor 8, rough alignment is performed so that the pupil Ep of an eye to be examined reaches the center part of the monitor 8. After the finish of the rough alignment, when the switch is changed over to an S6-side to allow the second illumination light source 6 to light, beam is transmitted through the convex mirror 2 to illuminate the anterior part Ex and the reflected beam is transmitted through the convex mirror 2 to pass through the objective lens 1 and further through the wavelength permselective mirror 4 to reach the imaging means 7. At this time, the image of the anterior part is projected on the monitor 8 in a magnified state. Therefore, an observation range can be arbitrarily magnified without using a movable part.
