Title: Transformer sealed with sulfur hexafluoride gas
Inventor: MORIYAMA IKUICHI
IPC: H01F27/32
Filed: 1978-09-14
Abstract: PURPOSE: To improve hydrolytic, mechanical, and electrical characteristics as well as life, by utilizing a polyester film whose thickness is 12, 16, 25, or 38μ.  
     CONSTITUTION: A polyester film is heated for a long period in a closed system which contains a sulfur hexafluoride gas. As a thickness of the film increases, reduction rates in tensile strength and elongation increase, and their influence is larger at elevated temperatures. Especially when the thickness is 38μ or more reduction in elongation is prominent, while if it is 12μ or less, the film tends to break or hane pin holes. Therefore, when a film with a thickness of 12, 16, 25, or 38μ is used, a thin insulation thickness can be obtained in a certain electric field. If the film is used together with a fibrous insulator in a equipment, an influence of moisture is gerat and the effect of the film thickness is large, thus reducing mechanical strength as well as insulation withstand voltage. When the film thickness of 12, 16, 25, or 38μ is selected, a transformer sealed with a hexa sulfur fluoride gas, which has good mechanecal characteristics, is obtained.

Title: Luminescent semiconductor element
Inventor: SUGIMOTO MITSUNORI
IPC: H01L31/14
Filed: 1978-09-14
Abstract: PURPOSE: To increase laser intensity and break-over voltage as well as to reduce a current density at the start of oscillation by laying III∼V group compounds into six layers such as n-p-n-p-n or p-p in such a way that width of a forbidden band of the forth and sixth layers is wider than of the fifth layer, and width of the forbidden band of the first and second layers is wider than that of the third layer.  
     CONSTITUTION: A multilayer consists of n-type and p-type GaAlAs 1 and 2, n-type GaAs 3, n-type GaAlAs 4, n-type GaAs 5, and p-type GaAlAs 6, and each of which has a required width of a forbidden band. When the elemint that is being "off", receieves a light ray hv, the ray passes through the first and second layers and is absorbed in the third layer, thus turning on the element by means of the photo-trigger. Then the condition of energy changes, and the element oscillates because of a double-hetero structure of layers 4∼6. At this time, all carriers are sealed off due to the given constitution of the forbidden band width, therefore a punch-through does not take place even if a starting current density Jth is low, and the active layer 5 is thin and the current Jth is small; thus a high break-over voltage is kept. In addition LED does not actuate, and a large power oscillating light is obtained. A light amprification rate is also high.

Title: Liquid crystal module
Inventor: NISHIO TOSHIYA
IPC: G02F1/1335
Filed: 1994-05-26
Abstract: PURPOSE:To uniformize the temp. of a liquid crystal cell as a whole by disposing a buffer material having good thermal conductivity between a liquid crystal cell and a metal frame and disposing a buffer material having low thermal conductivity on the rear surface of the liquid crystal cell thereby hardly transferring heat from an illuminating means to the liquid crystal cell. CONSTITUTION:The liquid crystal cell 1 is housed in a metal frame 3. The illuminating means 5 is disposed on the rear surface of the liquid crystal cell 1. A first buffer material 6 disposed on the front surface of the liquid crystal cell 1 has good thermal conductivity and is interposed between the liquid crystal cell 1 and the metal frame 3. On the rear surface of the liquid crystal cell 1, a second buffer material 7 having lower thermal conductivity than the first buffer material 6 is disposed. Heat emitted from the linear light source 52 is transmitted to the frame body 4 but hardly transmitted to the liquid crystal cell 1 because the thermal conductivity of the second buffer material 7 is low. On the other hand, heat transmitted from air or the like to the liquid crystal cell 1 is transmitted to the metal frame body 3 and radiated into air because the thermal conductivity of the first buffer material 6 is high.

Title: Cooking device
Inventor: UNO TOSHIO
IPC: G10K15/04
Filed: 1985-05-25
Abstract: PURPOSE:To enable to enunciate various data positively and accurately without yielding problems such as cost increase and a space, by connecting one buzzer to the output port of a control part, and directly supplying a signal having a frequency corresponding to the data to be reported to the buzzer. CONSTITUTION:The terminal of a buzzer 9 is directly connected to an output port P1 of a microcomputer 10. A signal corresponding to the input operation of a cooking-condition input key, is inputted to the microcomputer 10 from a key input part 24. Every time the key is depressed, a pulse signal of, e.g., 1kHz is outputted from the output port P1. Then, the buzzer 9 is vibrated at 1kHz and a buzzer sound having a sound pressure without unpleasant feeling is generated at a tone corresponding to the vibration. Thus the user can confirm that the pushing operation is accurately performed. When the cooking is finished, it can be confirmed by the similar way. In this method, problems such as cost increase and a space are not yielded. Various data can be reported to the users positively and accurately by using only one buzzer.

Title: Fabrication of semiconductor device
Inventor: SATOU YASUHISA
IPC: H01L21/28
Filed: 1982-06-30
Abstract: PURPOSE:To connect an impurity diffused region and a high temperature melting point metal silicide wiring with a low connecting resistance by covering the surface of semiconductor layer with an oxide film and a silicon nitride film for alleviating stress after implanting impurity ion into said semiconductor layer. CONSTITUTION:An As implanted region 9c is formed, for example, by ion implantation of As at the upper surface of the P type Si substrate 3 with a gate electrode 8 used as the mask. After removing a gate oxide film 7 exposed to the substrate surface, an SiO2 film 10 and an Si3N4 film 11 for alleviating stress are formed on the upper surface of substrate 3. Thereafter, a lower insulating film 12 is formed on the substrate 3. Next, a contact hole 13 which exposes the surface of film 11 is formed on the film 12. The substrate 13 is heated in order to diffuse As and thereby to form a source region 9'a and a drain region 9'b. In this case, since the upper surface of region 9'b is covered with the films 10 and 11, a high sheet resistance is not formed on the surface of the region 9'b. Next, the film 10 in the hole 13 is removed and the metal silicide wiring 14 is connected to the region 9'b.

Title: Method of manufacturing stator of rotary electric machine
Inventor: HONDA KATSUHIKO
IPC: H02K15/04
Filed: 1978-09-14
Abstract: PURPOSE: To transfer a coil and a core to a coil end processing stage without deforming the end of the coil and enable the complete automation of manufacture of a stator, by inserting a coil drop-off prevention wedge in between stator slots after coiling by a series winder.  
     CONSTITUTION: After a wire is coiled in the stator slots 5 of a stator core 1 by a series winder, coil drop-off prevention wedges 7 are automatically inserted in between the adjacent stator slots 5. The coiled wire and the core are then transferred to a coil end processing stage wherein sleeves are fitted on the ends of the coiled wire, the ends are bound with threads, lead wires are connected to the ends of the coiled wire or other similar work is performed. Since the coiled wire 4 is prevented by the wedges 7 from dropping off due to vibration during the conveyance of the coiled wire, its ends 6 are not deformed and the coiled wire can be transferred to the end processing stage as the ends of the wire extend straight in a prescribed direction. Therefore, the complete automation of manufacture of a stator is facilitated.

Filed: 1992-05-06
Abstract: PURPOSE:To reduce the abrasion of a magnetic head used at the time of high- speed revolution in a rotary magnetic head device having two recording/ reproduction modes, where a rotating drum is turned at high speed and low speed. CONSTITUTION:A magnetic head 5 used at a low-speed revolution mode is fixed to a rotating drum 2. A magnetic head 6 employed at a high-speed revolution mode is fastened to a head mounting base 24. A head sliding frame 20 fixed to the rotating drum 2 is disposed slidably in the radial direction of the rotating drum 2, and energized elastically by a tension spring 29 toward the center of rotation. Consequently, the magnetic head 6 is projected from the outer circumferential surface of the rotating drum 2 against the elastic force of the tension spring 29 by the centrifugal force of the rotating drum 2 only at the high-speed revolution mode, is brought into contact with a magnetic tape 1, and conducts the recording/reproduction of a signal. Accordingly, the contact time of the magnetic head, which is employed at the high-speed revolution mode and is easy to be abraded, with the magnetic tape can be shortened, thus lengthening the lifetime of the head.

Abstract: PROBLEM TO BE SOLVED: To retrieve an image inside an image data base at high speed by compressing images with high density by increasing the resolution of candidate images and performing matching again when the degree of coincidence between a retrieval template and the candidate images is higher than a threshold value. SOLUTION: Concerning the specified image, a pattern template is converted to a wavelet pattern (S30). Afterwards, the candidate images are correlated with a converted pattern (S31) and it is decided whether the converted pattern is suitably matched with any candidate image or not (S32). When that pattern is suitably matched, that candidate image is intermediately correlated (S33) and another similar match test is executed (S34). Similar processing is performed (S35-S37), a detailed correlation is taken and it is checked whether the completely correlated image is coincident or not (S37 and S38). When any image coincident with the completely correlated image is found out, it means the desired image is retrieved (S38).
