Title: Gallium nitride-based compound semiconductor light-emitting element
Inventor: MANABE KATSUHIDE
IPC: H01L21/205
Filed: 1988-09-16
Abstract: PURPOSE:To obtain a thick N-layer whose crystal property is good by a method wherein an AlN buffer layer is formed on a sapphire substrate and an N-layer composed of an N-type GaN-based compound semiconductor is formed on it by a halide vapor growth method. CONSTITUTION:A sapphire substrate 2 is attached to a susceptor of an MOVPE apparatus; an AlN buffer layer 3 is formed; after that, an N-type GaN layer 4 is formed at a growth speed of about 1mum/min by using a halide vapor growth apparatus. Then, a second N-type layer 8 of N-type GaN and an I-type GaN layer 5 are formed by an MOVPE method; electrodes 6, 7 are evaporated; a light-emitting diode is completed. When the second N-layer 8 which has been grown precisely by the MOVPE method is formed on the first N-layer 4, a crystallinity of the I-layer 5 can be made much better.

Title: Background density adjusting circuit for optical reading system
Inventor: YAMAMOTO TETSUMICHI
IPC: H04N1/407
Filed: 1984-11-05
Abstract: PURPOSE:To produce an excellent reproduction of an original that includes half tone by discriminating whether or not the image information is a background information, and by controlling the storage time of the information by the image sensor so that the peak value on the white-side of the information coincides with the prescribed reference value in case the information is discriminated as a background information. CONSTITUTION:Clock pulses CK1 and CK2 are obtained by a control signal generating circuit 11. The storage time adjusting part of the generating circuit 11 is composed of a variable divider 52 and a counter 51. The dividing ratio of the variable divider 52 is decided by the counter 51, and the divider 52 divides the CLK1 as referring to the dividing ratio, and forms the clock CK1. Therefore, the more the counter 51 counts up, the larger the dividing ratio is made, and the period of the output clock CK1 of the variable divider 52 becomes longer. Inversely, the counting down makes the dividing ratio smaller and the period of the same clock CK1 shorter. By adjusting the period of the clock signal in such a manner as above, the output voltage of an image sensor 10 is controlled to maintain the background density constant.

Title: Iron-base sintered valve seat and its manufacture
Inventor: AOKI NORIMASA
IPC: C22C38/00
Filed: 1998-08-19
Abstract: PROBLEM TO BE SOLVED: To improve high temperature wear resistance, strength, and machinability by dispersing, through a matrix, a compound phase which consists of a mixed-grain group of Cr carbide grains and Cr sulfide grains and a ferritic phase or a mixed phase of ferrite and austenite, each of the phases surrounding the above mixed-grain group in the iron-base. SOLUTION: Mixed-grain groups, where Cr carbide grains and Cr sulfide grains are present as a mixture, are allowed to exist mixedly in the matrix of an iron-base sintered valve seat. The periphery of each grain group is surrounded by a ferritic phase or a mixed phase of ferrite and austenite to form a compound phase having the grain group as a nucleus. By dispersing the Cr sulfide grains having self-lubricity together with the hard Cr carbide grains, improved machinability as well as high wear resistance can be provided. Owing to high Cr concentration, the ferritic phase or the mixed phase of ferrite and austenite can provide excellent toughness and increased material strength and also can act as a buffer against mating parts. It is preferable that the grain groups comprise, by area ratio, 3 to 25% of the metallic structure.

Title: Ball valve for germ-free line
Inventor: MATSUOKA TATSUHIKO
IPC: F16K5/06
Filed: 1996-09-04
Abstract: PROBLEM TO BE SOLVED: To improve the characteristic of the ball side surface part of a ball valve apt to be subjected to a temperature rise failure by providing a passage for passing steam between the ball side surface of the ball valve and the body of the ball valve. SOLUTION: Steam is supplied from a steam inlet 8 and passed through a groove 9, and the condensed water of steam is discharged from a discharge port 10. At this time, it is necessary to lay out the steam inlet 8, the groove 9 and the discharge port 10 so that the condensed water not discharged from the discharge port 10 is not stayed in the passage of steam, and the steam is carried from above to down. Consequently, a temperature rise failure is reduced, whereby the production failure by bacterial contamination caused by the temperature rise failure can be reduced. The opening and closing frequency of the ball valve in sterilization can be reduced, and the life of the valve can be extended.
