Title: Flap of leather backpack
Inventor: IZUMI MASAYOSHI
IPC: A45C3/02
Filed: 1998-06-19
Abstract: PROBLEM TO BE SOLVED: To solve such problems of a traditional leather backpack that cash or important papers put in a pocket in a flap of the backpack may fall and be lost when the opening of the pocket is turned down because the flap is opened/closed with its bottom edge being the center of the movement, and that when a zipper is attached to the pocket to prevent important articles stored there from falling, a user may seldom open/close the zipper in lesson and rest hours and not notice the existence of such articles, so that the user often forgets to hand or show the articles to teachers or parents. SOLUTION: An open/close zipper 2 is attached to the opening at the bottom edge of a translucent material 1 through which articles can be seen even when the material is double-layered. The top edge and both sides of the material 1 are sewn to the rear surface of the flap 3 of a backpack, and a first pocket P1 is formed between the layers of the material 1. And a second pocket P2 is formed between the rear surface of the double-layered material 1 and the flap 3.

Title: Semiconductor laser
Inventor: NOMURA HIDENORI
IPC: H01S5/00
Filed: 1985-08-05
Abstract: PURPOSE:To obtain a semiconductor laser having a current narrowing structure characterized by an excellent current blocking characteristic and small electrostatic capacitance, by utilizing the physical phenomenon, in which the resistance of a high resistance semiconductor, which has been grown epitaxially, is decreased by the impurity diffusion from a neighboring layer after the growing. CONSTITUTION:In a regrowing process by a molecular beam epitaxy method, a cap layer 5 is evaporated during the heating of a substrate before growing. A high concentration layer of Be is formed on the surface of a confinement layer 4. When a high resistance layer 6 is grown on the confinement layer 4, a high resistance layer 6 in a region at the upper part of a mesa stripe becomes a Be doped state owing to the thermal diffusion of Be. The resistance of the layer 6a becomes low. A current path is automatically formed on an active layer 3. Even in the high resistance layer 6 other than the region at the upper part of the mesa stripe, solid phase diffusion of Be from an embedded layer 7 is yielded. Since the doped concentration of the embedded layer 7 is not so high, the high resistance state is maintained intact, and the function of a current blocking layer is provided.

Title: Circular deflection signal generating circuit
Inventor: SUZUKI TOSHIO
IPC: G09G5/20
Filed: 1988-07-12
Abstract: PURPOSE:To draw a circle of optional size with constant brightness by multiplying a cosine function value and a sine function value which is obtained by referring to a trigonometric function table with a pointer according to referring intervals of the table calculated according to the size of the circle to be displayed by the radius of the circle, and generating a deflection signal by analog conversion. CONSTITUTION:Cosine function values and sine function values which are obtained by dividing a cosine function and a sine function at specific intervals respectively are stored in the trigonometric function table 13. Then an arithmetic circuit 11 calculates the referring intervals of the trigonometric function table 13 according to the size of the circle to be displayed and the pointer 12 is driven according to the referring intervals to obtain the cosine function value and sine function value from the trigonometric table 13. Those cosine function value and sine function value which are obtained with the pointer 12 are multiplied by the radius R of the circuit to be displayed and the arithmetic results are converted into analog signals to obtain an X-axial deflection signal and a Y-axial deflection signal. Consequently, the brightness density on the circumference can be made constant without reference to the size of the circle to be displayed, so the circle of optional size can be drawn with the constant brightness.

Title: Mirror with heater and manufacture thereof
Inventor: NAGAOKA MAKOTO
IPC: B60R1/06
Filed: 1997-06-13
Abstract: PROBLEM TO BE SOLVED: To provide sufficient anti-corrosion property without deteriorating any performance of temperature rising characteristic, etc., by setting an insulating moisture-proof layer on the mirror outer peripheral part provided with an electrode thicker than that on the mirror central part. SOLUTION: A heat resistant film 2 is formed on the back surface of a mirror substrate 1 and one pair of mutually facing electrodes 3a, 3b are provided on the heating resistance film 2 for the purpose of applying electrification thereto. And insulating moisture-proof layer 7 is formed on the heat resistant film 2. In this case, electrodes 3a, 3b formed by using copper or silver paste are extremely more corrosive than the film 2 made from chromium, etc., and for the purpose of preventing the electrodes from corrosion, the film thickness of the insulating moisture-proof layer 7 near an electrode is required to be made thicker than the film thickness necessary for electric insulation. Therefore, the film thickness of the insulating moisture-proof layer 7 is made thicker on the side of the mirror outer periphery where electrodes 3a, 3b are provided than that of the mirror central part.  In this case, although such a bad influence as a too long time required for removing water drops may possibly take place owing to slow temperature rise of the mirror, the mirror outer peripheral part where electrodes 3a, 3b are formed may have no influence on our power of visual recognition.
