Title: Bicycle parking unit
Inventor: FUJITA TAKESHI
IPC: E04H6/06
Filed: 1997-02-18
Abstract: PROBLEM TO BE SOLVED: To eliminate the need for members such as guide rails and to manufacture a bicycle parking unit at very low cost by forming a guide rail of a bicycle placement body that can be placed in and out from a substrate freely on the top of the substrate. SOLUTION: A bicycle placement body 2 with an approach guide route 2a for a bicycle, is provided in a manner that allows it to be put in or out from one end of a substrate 3 in a roughly horizontal state. In addition, the bicycle placement body 2 pulled out by a prescribed length from one end of the substrate 3 is structured so as to be turned downward at one end of the substrate 3. In such bicycle parking unit 1, the top face 3a of the substrate 3 forms a guide rail for the bicycle placement body 2 that can be put in or out from the substrate 3. Therefore, there is no need for attaching members such as a guide rail, the bicycle placement body 2 can be placed on the top face of the substrate 3 in a slidable manner. Therefore, it is possible to manufacture a very low-cost bicycle parking unit.

IPC: H01S5/00
Filed: 1989-02-13
Abstract: PURPOSE:To prevent deterioration of end faces due to light absorption and damage thereof and thereby to attain high reliability and high output by a method wherein {110} end faces in the opposite ends of an active layer formed on a (001) plane are formed of a layer buried in the same composition with the active layer by growth on a (111) plane. CONSTITUTION:An n-type (Al0.4Ga0.6)0.5In0.5P clad layer 2, a Ga0.5In0.5P active layer 3, a p-type (Al0.4Ga0.6)0.5In0.5P clad layer 4 and a P<+> type GaAs cap layer 5 are made to grow sequentially on an n-type GaAs substrate 1 on a (001) plane. Next, a groove extending in the direction intersecting the direction of propagation of a laser light perpendicularly is formed so that a (111) plane appears from the surface. Thereafter a Ga0.5In0.5P layer 6 is made to grow selectively only on the (111) plane of the groove. Then, a p-type electrode 7 is formed on the GaAs contact layer 5 and an n-type electrode 8 on the back of the GaAs substrate 1. End faces 9 are made by cleavage in a part wherein the Ga0.5In0.5P layer 6 is formed. Since deterioration of the end faces is reduced in a semiconductor laser thus obtained, reliability is improved, optical breakdown of the end faces is prevented and thereby a maximum light output can be improved.

Filed: 1997-02-03
Abstract: PROBLEM TO BE SOLVED: To obtain highly pure silicon nitride powder by treating silicon nitride powder containing at least one of chlorine and fluorine as an impurity in an atmosphere containing steam in a specific temperature range to efficiently remove the impurity. SOLUTION: This method can suitably applied to silicon nitride powder obtained by a method for directly oxidizing metal silicon.

The silicon nitride powder is treated with a carrier gas containing steam. The steam is preferably contained in the treating gas in an amount of 0.1-5vol.% based on the whole volume of the carrier gas. The carrier gas includes inert gases such as nitrogen gas and argon. The treatment using the gas is carried out at a temperature of 1,150-1,500 deg.C. Therein, e.g. a pressure type tunnel oven, etc., are used.

Title: Removal of free formaldehyde from urea resin particle dispersion
Inventor: NAGAOKA MUNEO
IPC: C08G12/00
Filed: 1984-02-27
Abstract: PURPOSE:To remove free formaldehyde easily from a urea resin particle dispersion, by adding sulfurous acid (salt) to the dispersion at a specified molar ratio to the free formaldehyde contained therein, reacting them and adjusting the final pH to around a neutral value. CONSTITUTION:Formaldehyde is condensed with urea to form a urea resin particle dispersion containing free formaldehyde. To this dispersion, sulfurous acid (salt) (e.g., sodium sulfite or acid sodium sulfite) in an amount of 0.5-1.5mol per mol of the free aldehyde is added, and the reaction between them is effected. The final pH of this dispersion is adjusted to 5-9 in order to prevent the bisulfite compound as the reaction product from forming free formaldehyde by decomposition during storage. In this way, a urea resin particle dispersion containing no free formaldehyde can be obtained.

Abstract: PROBLEM TO BE SOLVED: To provide the output of an uniform data width independent of inputted serial data by providing a difference for one clock in the timing of signals for successively outputting held serial data and preventing both change points from matching. SOLUTION: As output enable signals 5a(1-1), Q(1)-Q(1) of a shift register 5 are turned to the output enable signals 5a(1-1) of respective gate circuits 3(1-1).

Filed: 1984-02-23
Abstract: PURPOSE:To improve the variation in the characteristics of a fluorescent lamp as well as the decrease in luminous flux by providing the peripheral area of a bottom stem with a paste reservoir and then packing a binder-free glass frit paste in the reservoir to fuse the outer tube to the bottom stem. CONSTITUTION:The periphery of a bottom stem 2 is provided with a circumference wall 14 to form a paste reservoir 15 between the circumference wall 14 and an outer tube 1. Next, a binder-free glass frit paste 13' is packed into the paste reservoir 15. Next, the frit paste 13' is dried before performing sintering, thereby fusing the outer tube 1 to the stem 2. Owing to the paste reservoir 15, the glass frit paste 13' is reliably held and therefore it is not necessary to add a binder during application. Accordingly, even when the glass frit paste 13' penetrates into the lamp, there is no possibility that the characteristics of the lamp are adversely influenced by the incomplete combustion of a binder.
