Title: Manufacture of clutch facing
Inventor: ARIMA KEITARO
IPC: F16D69/00
Filed: 1988-03-22
Abstract: PURPOSE:To inexpensively obtain a clutch facing having no generation of a noise by employing glass fiber to which at least solid lubricant adheres as a base material fiber. CONSTITUTION:Glass fiber or glass fiber and asbestos fiber are employed as a base material fiber. As solid lubricant adhering to the surface of the fiber, molybdenum disulfide, graphite, antimony sulfide, etc., are employed, the glass fiber is dipped in solution in which it is dispersed in dispersing medium such as water, alcohol, or the dispersion solution is sprayed on the glass fiber. This is formed in a yarnlike or tapelike state or the like, pastelike filler is pressurized and adhering, and then dried. This is preliminarily molded by a cross winding method, a spirally winding method. etc., in a laminate state, heated and compressed to be molded in a metal mold, and baked to obtain a product. Thus, a stable frictional performance is obtained, thereby preventing it from generating noise at the time of clutch operation.

Title: Bromination of an alkyl arene
Inventor: FUIRITSUPU JIEEMUBU TAANAA
IPC: B01J19/12
Filed: 1989-03-17
Abstract: Selective bromination of alkylarenes to the alpha monobrominated derivative is desirable as a precursor for the selective production of, for example, the corresponding alcohols. The product can be obtained by a photolytic reaction between the substrate, hydrogen peroxide and hydrogen bromide in approximately equimolar ratios in an organic solvent, but improvement in the yield of the product coupled with similar or improved selectivity in its production was either not achieved or was actually impaired by a range of variations in the ratios and by omitting the solvent. The invention employs mole ratios of H2O2:substrate of 0.1:1 to 0.4:1, preferably 0.2:1 to 0.33:1 and of H2O2:bromide of 1:1.2 to 1:2, preferably about 1:1.3 to 1:1.8 and progressive introduction of the H2O2, either in the presence or absence of the solvent, whilst irradiating with light preferably having principal emmisions in the range of 250 to 600 nm, and the process thereby achieves either or both of improved yield and improved selectivity of the alpha monobrominated product. The reaction mixture is preferably maintained at 50 to 70 DEG C. The process is especially suitable for deactivated alkylarenes, such as o-nitrotoluene.

Inventor: HINOTANI KATSUHIRO
IPC: H01J61/30
Filed: 1987-03-20
Abstract: PURPOSE:To obtain the uniform luminance of a fluorescent lamp eliminating the nonuniformity of luminance even when a reinforcing glass member is used by roughening the outer surface of the glass plate, the luminous surface of one of a pair of grass plates. CONSTITUTION:The upper and the lower surfaces of a reinforcing glass member 11 are positioned facing to uncoated portions 5, 6 of phosphor on the upper and the lower glass plates 1, 2 respectively, and a reflecting film 7 is produced on the outer surface of the glass plate 2 at a position corresponding to the uncoated position 6.

Title: Switch
Inventor: KONISHI KEISUKE
IPC: H01H13/36
Filed: 1988-03-18
Abstract: PURPOSE:To detect the slippage of position correctly at the position apart from the passing position of a substance by lighting a warning LED and reporting the slippage of position to the outside, when the fixing position of a limit switch is shifted and the fact that the slippage exceeds an adequate scope when the substance passes is detected. CONSTITUTION:When the fixing position of a limit switch is shifted and the turning angle of a lever and the stroke of an operation piece 20 are reduced exceeding an adequate scope in the passage of a substance, the contact output cannot be acquired from a switch SW 1. As a result, after a counter 43 is reset, and when the switch output is OFF, and no comparison output is given to a comparator 47 from a starting detector 46, the counted value of the counter 43 and the output of a data output member 48 are not coincident. Consequently, as well as a warning LED 29 is lighted from the comparison output, the output of the position slippage detection is picked up through a transistor Tr 2. This signal reports the position slippage to the outside through the limit switch main body.

Title: Method of compound semiconductor crystal growth on group iv element substrate
Inventor: OGASAWARA KAZUTO
IPC: H01L21/20
Filed: 1987-03-19
Abstract: PURPOSE:To suppress the generation of an antiphase domain, by gradually raising a temperature on a group IV element substrate which is flattened by surface treatment so that epitaxial growth is performed by single atomic layer control. CONSTITUTION:Beams of a group III element (e.g., Ga) are radiated on a group iv element substrate (e.g., Si substrate), which is flattened in a state of an atomic layer level, under the coating of a group v element (e.g., As) so that one atomic layer is made to grow. Further, a temperature is raised by a reflection type high energy electron beam diffraction method until a streak pattern is recognized. While the temperature is raised gradually to 600 deg.C to 680 deg.C in succession, beams of the group III element are radiated intermittently to make the one-atom layers grow one by one. Hence, an anti-phase domain on the group iv element substrate can be suppressed.
