Inventor: MORITA KIYOTAKE
IPC: G11B5/712
Filed: 1980-03-10
Abstract: PURPOSE: To form a strong covering by film and to suppress the change in magnetic properties by the elapse of time by a method wherein a fine ferromagnetic metal powder or its surface is covered with an oxide film and then is brought into contact with sulfur dioxide.  
     CONSTITUTION: This process uses a ferromagnetic metal powder such as one obtained by reduction with hydrolyzing an organic salt of a ferromagnetic metal, reduction products of water-containing metal oxide or its mixture with other metals, a vacuum evaporated product, or a pyrolysis product of a metal carbonyl cpd. The powder is brought into contact with a gas containing about 100ppm of sulfur dioxide at temperatures of 100W400°C, for example, for 30minW50hur, for example. Thus, the process enables to achieve stabilization by using a gas phase and therefore is valuable from practical point of view. This effect can be enhanced by covering the above powder with an oxide in advance.

Inventor: SUZUKI KATSUHISA
IPC: F28D19/00
Filed: 1984-02-17
Abstract: PURPOSE:To eliminate the necessity for positioning a high-temperature fluid passage and a low-temperature fluid passage adjacent to each other so as to facilitate the piping work by heightening the vapor pressure inside a fluid medium storage section which is equipped with an internal vapor pressure heightening device. CONSTITUTION:The fluid medium inside a pressure generator 21 is vaporized by being heated by solar heat, and the gasified fluid medium inside the pressure generator 21 flows into a fluid medium storage section 2 through a pressurizer 24, the vapor pressure inside of which rises to permit the recovery of the waste heat. When the liquid medium which has been collected inside a liquid return passage 6 after being liquefied while passing through a low-temperature fluid side heat exchanger 3 is supplied to the fluid medium storage section 2, the vapor pressure inside a high-temperature fluid side heat exchanger 1 and the vapor pressure inside the fluid medium storage section 2 are equalized to allow a part of the fluid medium inside the high-temperature fluid side heat exchanger 1 to flow by virtue of gravity into the pressure generator 21 through a fluid medium supply passage 22, and so, it becomes unnecessary to position the high- temperature liquid passage and low-temperature fluid passage adjacent to each other.

Title: Vehicular corner pole
Inventor: ANDO HIROSHI
IPC: B60R19/48
Filed: 1996-01-24
Abstract: PROBLEM TO BE SOLVED: To dispense with a gear mechanism of complicated construction by directly engaging and connecting the drive shaft of an ultrasonic wave motor with the rack gear of a drive cord through a pinion. SOLUTION: By a driver manipulating a changeover switch 18 provided near a driver's seat or the like, an ultrasonic wave motor 15 makes a positive/ reverse rotation and a drive cord 13 advances/retreats. Thus the corner pole element 12a of a corner pole assembly body 12 expands/shrinks. This ultrasonic wave motor 15 being small in size, light in weight, low speed but having high torque, it smoothly advances/retreats the drive cord 13 even if its drive shaft 15a is directly engaged and connected with a rack gear 13a of the drive cord 13 through a pinion 16. Because a complicated gear mechanism is dispensed with by such a direct drive system, a casing 21 for storing the ultrasonic wave motor 15 and the pinion 16 can be made of a very simple construction.

Filed: 1995-01-25
Abstract: PURPOSE: To provide a Li secondary battery excellent in charge and discharge cycle characteristic in which the capacity deterioration by repeated charge and discharge is minimized by setting the surface form of a conductive base after a film containing an active material is formed to a prescribed maximum recessed depth. CONSTITUTION: This battery contains a positive electrode 1, a negative electrode 2, a separator 3, an electrolyte 4, a battery case 5, and insulators 6, 7. In the manufacture of the positive electrode, a positive electrode coating material containing LiNi oxide, scaly graphite and polyvinylidene fluoride of 91, 6, and 3 parts by weight, respectively, is prepared. Similarly, NMP is similarly added to 90 parts by weight of artificial graphite and polyvinylidene fluoride as negative electrode materials to prepare a negative electrode coating material. These positive electrode and negative electrode coating materials are applied to the positive electrode and negative electrode to form films.  The surface form of the conductive base after film formation is set to 0.5μm or more and not more than 2μm by maximum recessed depth Rv, preferably, 0.7μm or more and not more than 1.5μm. When Rv is less than 0.5μm, the adhesion between the film and the base is reduced by repeated charge and discharge to deteriorate the capacity of the battery. When Rv is 2μm or more, the base is mechanically fatigued by repeated charge and discharge to cause the deterioration of capacity by cracking and rupture.

Filed: 1999-02-08
Abstract: PROBLEM TO BE SOLVED: To prevent the coloration of an optical element and to enable the observation of images having a high grade by providing the above system with a means which has an optical element formed of plastic material and cuts UV rays to an observation side from the optical element. SOLUTION: A protective plate 6 disposed on the observer 5 of a prism 4 plays the role of preventing the direct adhesion of dust on the prism 4 and also plays the role as a means for cutting the UV rays. A protective plate 6 is obtained by forming multilayered films 6b of thin films of a dielectric substance on both surfaces of a flat plate 6a made of acryl. The multilayered films 6b prevent the reflection of the rays in a visible region of the incident light on the protective plate 6, thereby increasing transmission and increasing the reflection of the rays of a UV region toward an incident direction. The light from the image displayed on an LCD 1 is made incident on the first surface 4a of the prism 4, is then totally reflected on the second surface 4b, is reflected by the third surface 4c and is emitted from the second surface 4b.  The observer 5 is able to observe the enlarged image as if the image is displayed on the sky just before the eyes.

Title: Semiconductor pellet
Inventor: OKAMURA YOSHIO
IPC: H01L21/52
Filed: 1988-02-10
Abstract: PURPOSE:To relieve stress externally exerted to a semiconductor pellet, by bonding a pellet body to a die bonding solder while providing a linear region where no metal layer is formed in the bonding interface between them. CONSTITUTION:In order to enable a pellet body 1 to be bonded to a die bonding solder 6 with enhanced adhesive force, a metal layer 2 is previously formed on the die bonding surface of the pellet body 1. This metal layer 2 is not formed all over the die bonding surface but an annular groove 3 without the metal layer is formed inside and along the periphery of the pellet body 1. When a semiconductor pellet is die bonded to a radiation plate 5 by means of the soldering material 6, a space is defined in the groove 3 where the metal layer 2 is not present. If external force is applied to the pellet after it is sealed with resin, dislocation is caused first in the radiation plate and the sealing resin enclosing the pellet, and then the force is applied to the layered structure itself on the radiation plate 5. Such external stress can be absorbed effectively because adhesion between the metal layer 2 and the soldering material 6 is broken by the groove 3.
