Title: Radiation type space heater
Inventor: NAKAMURA SHINICHI
IPC: F24C5/00
Filed: 1989-11-17
Abstract: PURPOSE:To enhance a heating efficiency, effect uniform radiation as a whole and widen a comfortable heating space by providing a radiant member applied with a far-infrared coating, which radiates radiant heat, between a reflecting plate and a heat source member. CONSTITUTION:A radiant member 17 disposed in front of a reflecting plate 15 is made of a stainless steel sheet or an aluminum-plated copper sheet, both being curved, and is constituted so as to have a given space 17a between the radiant member 17 and the reflecting plate 15. Combustion heat generated from a heat chamber 14 is in part radiated directly to the front side as radiant heat and is in part reflected by the reflecting plate 15 to be radiated as radiant heat. In the case of conventional radiation type heaters, radiation has been effected only from the portion of a reflecting plate, where the heat chamber is directly mirrored, and radiant heat from the upper part of the reflecting plate has not substantially been obtained. In the case of the heater of this invention, however, it is so designed that more uniform radiant effects are obtained by disposing the radiant member 17. Further, since square holes 18 are provided in the form of a lattice on the aforementioned radiant member, radiant heat from the reflecting plate 15 itself can also be radiated to the front side.

Title: Ultraviolet erasing type non-volatile semiconductor memory device
Inventor: BAN AKIRA
IPC: H01L21/8247
Filed: 1987-11-28
Abstract: PURPOSE:To reduce the load capacity of a boosting circuit and to reduce semiconductor chip area by charging with high electric potential electric power supply in the early period during the charging period of a word line and charging the word link by a boosting electric power supply in the latter period. CONSTITUTION:On reading, an address signal inputted to address signal input terminals 1a-1c is made into a logic '1' first. Thus, the output of an inverter 4 becomes the logic '1'. In this case, since FET 25 is in ON state, a word line 14 is charged to a high electric potential electric power supply level by the inverter 4. On the other hand, since an address sign of which logical value is zero is inputted to address signal input terminals 2a-2c. FET 8-10 become an ON state. However, since FET 7 is an OFF state, the voltage of a boosting electric power supply terminal 13 is not applied to the line 14. Then, when the line 14 reaches the high electric potential electric power supply level, FET 7 becomes an ON state and FET 25 becomes OFF state. Consequently, the line 14 is charged by the boosting electric power supply level of the terminal 13. Thus, the load capacity of the boosting circuit is reduced and the capacitor capacity can be minimized.

Filed: 1990-11-08
Abstract: PURPOSE:To improve resistance to oxidation and rusting by performing a surface treatment of fine particles of a ferromagnetic metal material or a ferromagnetic alloy material by alicyclic bivalent carboxylic acid and/or anhydride thereof. CONSTITUTION:A ferromagnetic metal particle for a magnetic recording medium comprises fine particles of a ferromagnetic metal material or a ferromagnetic alloy material and the fine material undergoes a surface treatment by a alicyclic bivalent carboxylic acid and/or anhydride thereof. A dewatering reaction is caused between a treating agent and the surface of the ferromagnetic metal particle to form a film by the treating agent on the surface of the ferromagnetic metal particle. The film prevents oxidizing reaction of the surface of the ferromagnetic metal particle which is progressing during the preservation of the ferromagnetic metal particle, during the preparation of a magnetic paint containing the ferromagnetic metal particle and during the preservation of the magnetic recording medium and the like. This improves resistance to oxidation and rusting thereby achieving excellence in secular stability.

Abstract: PROBLEM TO BE SOLVED: To provide a magnetic recording and reproducing device suitable for shortening the take-up time of a magnetic tape by selectively performing the press-contacting and detaching of a pinch roller to and from a capstan according to the take-up load torque of the magnetic tape. SOLUTION: The magnitude relation between the load torque required for the take-up of the magnetic tape 201 and the take-up torque of a reel turntable S102 is judged by a control microcomputer 300 in accordance with the number of revolutions of a drive section 102b of the reel turntable S102 detected by a sensor 299a.

Filed: 1992-11-12
Abstract: PURPOSE:To improve the transfer efficiency of data by including independently a reset command used to reset a 2nd permission condition storage means to three states of a cell circulating on a ring so as to warrant fairness of cell transfer. CONSTITUTION:A cell from a ring input section 101 is inputted to a cell reception transfer section 102 and a cell relay section 108, which discriminates the state of the cell. When the cell is idle and there is any channel allocated by a network management section 109 remains, the channel is set to the busy state and the cell with data set thereto is sent. When the channel is busy, the reception section 102 extracts information from a pay load when the cell is addressed to its own node and stores the information to a reception buffer 103 and revises the state to the idle state. Then, in the case of the right giveup state, the relay section 108 revises the state to the idle state when the cell is addressed to the node itself and sets a reset bit of the cell. Upon the receipt of the cell whose reset bit is set, a 2nd window size is reset. Thus, the fairness is warranted and the data transfer efficiency is improved.
