Title: Manufacture of semiconductor device
Inventor: SAKURAI HIROMI
IPC: H01L21/31
Filed: 1984-03-23
Abstract: PURPOSE:To separate elements of high accuracy and high quality by annealing an epitaxial layer formed in an insulating film hole, then polishing the surfaces of the epitaxial layer and the insulating film, thereby stabilizing the characteristic of an element formed on the layer and preventing the wirings from disconnecting. CONSTITUTION:An epitaxial layer 3 is formed in the hole of an SiO2 film 2 on an Si substrate 1, the entirety is heated and annealed at 1,200-1,300 deg.C for approx. 10-20sec to recover the crystallinity. Then, the surface is lightly polished. Since the frictional resistance abruptly increases if a projection is erased, the finishing point of the polishing can be simply observed, and can be mirror- polished with good reproducibility. The surface after polishing is completely flat, no disconnection of wiring occurs to stabilize the characteristic of an element formed on the layer 3, an element separating structure of high accuracy and high quality can be obtained merely adding simple step to the conventional steps.

Title: Heating vessel
Inventor: YOKOYAMA SUSUMU
IPC: A47J27/21
Filed: 1998-03-09
Abstract: PROBLEM TO BE SOLVED: To provide an excellent heating vessel which quickens responsiveness in the speed of a temperature detecting sensor such as a heat-insulating sensor, idling preventive sensor, etc., and which is excellent in the precision of temperature detection. SOLUTION: A heat transmitting plate 4 which comes into contact with the heat releasing surface of an electric heater 3 and the heat receiving surface of an object 2 to be heated, is arranged and to the heat transmitting plate 4, a temperature detecting sensor 6 is mounted. When the temperature is reduced, the temperature detection sensor 6 reduces the temperature quicker due to a cooling effect by external air. The temperature detection sensor 6 can sense quicker than by conventional thermal transmission due to the fact that the object 2 to be heated has been heated up to the established temperature by the heat of the heat transmitting plate 4 transmitted by the electric heater 3 and by the heat of the outer peripheral surface released from the electric heater 3 when the object 2 to be heated, is heated.  Accordingly, temperature control for heating or heat-insulating can be controlled at a high precision in a narrow temperature range against the established temperature.

Inventor: KAJIMOTO MASATSUGU
IPC: G03G15/06
Filed: 1982-04-07
Abstract: PURPOSE:To prevent generation of a black line on a copy even in case when a defect exists in a photoreceptor, by coupling a semiconductive scraping member and a scraper by a bias electric power source, and also electrically coupling them with an electrostatic latent image of the photoreceptor, too. CONSTITUTION:When voltage is applied from a bias electric power source 7 to a semiconductive scraping member 8 for adjusting the height of a magnetic brush which passes through in a developer 4 and is formed on a magnet roller 2, the leak is prevented even in case of high bias. When the magnetic brush contacts with the lower face of a rotary photoreceptor 1, an electrostatic latent image is developed. A cylinder 5 is insulated and the bias voltage does not operate directly on the photoreceptor 1, therefore, even in case when a defect exists in the photoreceptor 1, the bias electric power source is not damaged, and a bias current flows to the defective part, therefore, generation of a black line on a copy is prevented. In this regard, from the scraping member 8 and a semiconductive scraper 9, too, voltage is applied to the photoreceptor 1 through a carrier in the developer 4.

Title: Refrigerator
Inventor: WATABE MASATAKA
IPC: F25B41/06
Filed: 1988-03-10
Abstract: PURPOSE: To alleviate a temporarily high load of a compressor by providing a flow controller for increasing a flowing resistance to an increase in a refrigerant flow rate between an outlet of an evaporator and a suction port of the compressor. CONSTITUTION: A flow controller 6 is stepwisely formed at an inlet 7 side of a flowing passage in a large diameter and at an outlet 8 side in a small diameter. And, a sphere 12 as a valve disc is disposed to be urged by a spring 11 in the large diameter of the inlet 7 side. A refrigerant flow rate is substantially constant at a low pressure in this state. But, the sphere 11 is urged against the spring 11 to be abnormally high, and the small diameter if the outlet 8 side is closed or its opening degree is narrowed. Thus, a reduced pressure part 9 is generated to abruptly raise a resistance against the refrigerant flow. In this relation, the refrigerant flow is hardly increased from a certain value even if the pressure of a low pressure side is raised.

Title: Boiling point detecting method
Inventor: ASAKURA MASAHIRO
IPC: G01K7/00
Filed: 1988-03-11
Abstract: PURPOSE:To realize an economic method which performs accurate boiling point detection in a short time by detecting a point of time when the difference value of a value obtained by raising a temperature signal with respect to a liquid which is obtained from a temperature sensor to >=2nd power is maximum as a boiling point. CONSTITUTION:A CPU 7 detects the point of time when the difference value between the squares of the temperature signal with respect to the liquid which is obtained from the temperature sensor 3 at unit time, e.g. at every 10sec is maximum as the boiling point. Consequently, heating is started while the amount of water is 0.3l and the CPU 7 calculates temperature variation according to equations, so that the variation in water temperature nearby the boiling point, and DELTAn and DELTAn<2> are as shown in figures (a) and (b). The figure (b) shows that the DELTAn<2> indicates a maximum value nearby a real boiling point, and when [DELTAn<2>-DELTA(n+1)<2>]>l at a next sampling point (where l is a decrement in DELTAn), the boiling point is easily detected. This arithmetic does not depend upon the amount of liquid and highly flexible detection is made possible with the simple software of the CPU 7 which includes addition and subtraction and only a shift instruction.
