Title: Heat radiating device
Inventor: UNO HIROSHI
IPC: F24D7/00
Filed: 1985-06-25
Abstract: PURPOSE:To prevent feeling of air stream, ununiform room temperature distribution and noise during heating a room by a method wherein a control unit, which stops a fan during room heating operation and drives the fan during room cooling operation, is provided in the titled device. CONSTITUTION:The control unit 6 switches the operation of the fan 3, depending on whether it is room cooling operation or room heating operation. During room cooling operation, refrigerant is evaporated in a heat exchanger unit 7 and the control unit 6 drives the fan 3 to effect heat exchange in indoor air by forced convection and cool the room. On the other hand, during room heating operation, the refrigerant is condensed in the heat exchanger 7 and the control unit 6 stops the fan 3 to effect heat exchange in the indoor air by natural convection and heat the room. The fan 3 is stopped during room heating operation. Accordingly, noise is not generated, no air stream is felt by body and room temperature distribution is uniform, thereby making the room heating comfortable.

IPC: G02B7/10
Filed: 1988-06-07
Abstract: PURPOSE:To omit to discriminate a nonfocusing direction and to speed up focusing by determining a representative speed so that a 2nd lens group becomes out of focus in a specific direction. CONSTITUTION:A 1st group lens 1 is fixed to a lens frame 103, engaged with a fixed lens barrel 102 threadably at the best lens position, and fixed with a screw 104 after being adjusted.

Title: Manufacture of semiconductor device
Inventor: FURUTA ISAO
IPC: H01L21/76
Filed: 1984-07-04
Abstract: PURPOSE:To form silicon surface having no bird beak and isolated oxide film and also form a miniaturized wiring pattern and improve integration density by ion implantation of oxygen with high concentration up to the specified depth before formation of an isolated oxide film. CONSTITUTION:A buffering silicon oxide film 2 is formed on a silicon substrate 1 and a silicon nitride film 3 is then formed on such film. Next, after removing the silicon oxide film 3 from the area to form an isolated oxide film with the photo resist 5 used as the mask, the high concentration oxygen is ion implanted to the silicon substrate 1. Thereafter, the photo resist 5 is removed and annealing is carried out in the dry oxygen ambient. In this case, the high concentration oxygen reacts with the silicon within the silicon substrate 1 and thereby a silicon oxide film 2 is formed. After removing the silicon nitride film 3, an isolated oxide film 2 is formed by thermal oxidation. Thereby, an isolated oxide film 4 having no bird beak and flat silicon surface can be formed.

IPC: G11B11/105
Filed: 1994-06-22
Abstract: PURPOSE:To form magnetic domains whose sizes are smaller than a light spot diameter and facilitate high density recording by a method wherein regions whose magnetic characteristics, thermal characteristics and/or optical characteristics are different from those of the other regions are provided in the magnetic film of a magneto-optical recording medium. CONSTITUTION:At least a magnetic film 2 is provided on the disc-type substrate 1 of a magneto-optical recording medium. Regions 3 whose coercive forces are low are provided on the magnetic film 2. The regions 3 may be formed on the disc in various patterns. If they are formed in spiral patterns, they can be also used as tracks and accessed easily. At that time, the width of each region 3 is 0.4mum and the distance between the regions 3 is 0.3mum. The region whose coercive force is low has a higher sensitivity than the other region. Therefore, if a light beam having a proper intensity is applied to elevate a medium temperature, recording magnetic domains can be formed in the regions 3 only in the medium. With this constitution, the width of each magnetic domain is limited to the width (0.4mum) of each region 3 regardless of the wavelength of a laser beam, so that high density recording can be realized.
