Title: Information recording disk recorder
Inventor: YAMAGUCHI HIROHISA
IPC: G11B19/02
Filed: 1986-07-16
Abstract: PURPOSE:To stably perform consecutive write recording, by prohibiting jump just before the consecutive write recording is started. CONSTITUTION:A switching recording means 3 starts the recording of an information signal from an input terminal 5 after the cancellation of still reproduction, based on the input of a consecutive write recording start signal from an input terminal 4. In other words, a prescribed track retrieved by a retrieving means 1 is continued to be reproduced (still reproduction) repeatedly by a still reproduction means 2. In the above state, when the consecutive write recording start signal is inputted to a switching recording means 3 through the input terminal 4, the switching recording means 3 cancels the repeat reproduction of a prescribed recorded track by the still reproduction means 2, and also, switches the mode of a device to a recording mode from the first position of an unrecorded track positioned just behind the prescribed track, or from a time when a prescribed synchronizing signal in a new information signal is inputted from an input terminal 5, and starts the recording of the new information signal on the unrecorded track on an information recording disk.

Filed: 1988-07-05
Abstract: PURPOSE:To prevent a thin natural oxide film from being grown in a reduced pressure CVD furnace by changing the natural oxide film formed on a surface of a polycrystalline silicon layer in which a high concentration impurity is diffused to a silicon nitride film by a rapid nitriding process. CONSTITUTION:An oxide film 12 is formed by oxidization of a semiconductor substrate 11 surface, and a polycrystalline silicon layer 13 is deposited on the resulting oxide film 12. Then, a natural oxide film 18 is changed to a nitride film 19 by rapid nitrization. Further, a silicon nitride film 15 is deposited on the nitride film 19 by a reduced pressure CVD process, and a surface of the silicon nitride film 15 is oxidized to form an oxide film 16. Further, a second layer polycrystalline silicon layer 17 is deposited on the oxide film 16, into which impurity P is doped by a necessary amount. As a result, a stable thickness and large capacity thin insulating film can be formed on the polycrystalline silicon layer in which high concentration impurity has been doped.

Abstract: PURPOSE: To prevent boiling in an apparatus in which a heat exchanger using as a source of a burner is positioned in the upper part of a hot water reservoir connected to a solar heat collector, by detecting the hot water temperature in the lower  part of the hot water reservoir to permit the off-value of a temperature controlling  apparatus to be changed.  
     CONSTITUTION: The low temperature hot water in the lower part of the hot water reservoir 1 is supplied to the solar heat collector 11 by the operation of a circulating  pump 14, and the hot water obtained therein is returned to the hot water reservoir 1  to be stored in the upper part thereof. When the hot water is distributed, and if the  temperature is low, the burner 3 is operated to further heat the water to a predetermined value set by the temperature controlling apparatus 6. In this warm water heater,  heat sensitive parts 7, 20 are attached respectively to the upper part of the hot water  reservoir 1 and a position thereof at approximately the same level as the lower surface  of an inner can 2. An electric circuit is constituted such that the ON/OFF-values of  the temperature controlling apparatus 6 varies according to the resistance value of a  thermistor 20a of the heat sensitive part 20. Accordingly, if for example, the resistance  value of the thermistor 20a is low, the off-value of the appratus 6 is lowered, so that boiling is prevented even when a small quantity of hot water is delivered.

Title: Label of film for radiography and its forming method
Inventor: INAMI MASAHARU
IPC: A61B6/00
Filed: 1993-06-02
Abstract: PURPOSE:To provide a label which enables simple recording of photographic information by using all characters and symbols used in ordinary documents in a part of a film. CONSTITUTION:This label 5 of the film for radiography is formed by recording the photographic information as transmitted images of radiations on a part of the film for radiography to be formed with the photographic image of a subject by irradiating the subject with the radiations from a radiation source. The photographic information I1, I2 are inputted on the label 5 by a document editing device. The information I1, I2 are printed by a coating material for printing through which the radiations are non-transmittable. Since the photographic information is recordable by all the characters and symbols used for document edition, the exact display of a patient's name is possible and mistaking of the films by the same family and personal names does not arise. Even intricate medical data are easily displayed on the label 5 and are usable for later treatment as a reference treatment. The label 5 is usable as it is as the label of a preservation case.
