Title: Welding method of 9cr steel
Inventor: YOSHINO FUMITO
IPC: B23K9/23
Filed: 1984-06-12
Abstract: PURPOSE:To weld a 9Cr steel with the excellent resistance to cracking at a high temp. by using a welding material contg. specifically composed Ti, REM, C, Cr, Mo, Nb and adjusting adequately the content of O, N, Si and Mn in the weld metal. CONSTITUTION:The welding material contg., by the total weight of the welding material, 0.01-5.0wt% Ti and/or REM, <=0.15% C, 8-13% Cr, 0.8-2.3% Mo and <=0.15% Nb is used. The 9Cr steel is welded by adjusting the contents in the weld metal in a manner as to contain 0.015-0.060% O, 0.003-0.050% N, <=0.6% Si and <=3% Mn to prevent the generation of the cracking at a high temp. and to provide the weld zone having the mechanical performance at the same level as the mechanical performance of the base metal. The application of the 9Cr steel to a thick-walled structure at and under a high temp. and high pressure is thus made possible.

Title: Harness producing apparatus
Inventor: IKEDA YUUJI
IPC: H01B13/00
Filed: 1983-07-05
Abstract: The apparatus comprises first and second wire treatment stations (60 and 80). Wires (1) are fed through the second station (80) and their free ends are terminated to an electrical connector (2) at the first station (60). Wire lengthening rollers (58 and 59) are then operated to advance the wires by different lengths, so that they form loops between the stations (60 and 80). During such advance of the wires, wire tensioning rollers (91 and 104) are operated to keep the wires in tension between the tensioning rollers (91 and 104) and the wire lengthening rollers (58 and 59) and to pay out the wires into the loops. The wire lengthening, and the wire tensioning, rollers are then topped and the wires are simultaneously severed at the second wire treatment station (80) and the severed ends of the leads so formed are terminated to a second electrical connector (2 min ) at the second wire treatment station (80), after which, the terminated leads (1 min ) are ejected from the apparatus.

Title: Semiconductor photodetecting device
Inventor: HIGUCHI HIDEYO
IPC: H01L31/10
Filed: 1988-05-18
Abstract: PURPOSE:To respond fully even to incident light which has spread parts spatially and varies at great speed, by forming the whole other region with InP with the exception of an InGaAs photoabsorption layer which is buried in a buried layer. CONSTITUTION:As a light receiving part 3a absorbs rays of light having wavelengths 0.1 to 1.6mum, an incident light having the wavelengths 1.3mum coming to the light receiving part is absorbed in this place to change into a photoelectric current. On the other hand, the incident light coming to the outside of the light receiving part comes into an InP buried layer 5. As a band gap wavelength is shown by an expression: lambdagapprox.=0.92mum, the incident light having the wavelengths 1.3mum passes through the foregoing layer 5 and also passes through an n-type InP buffer layer 20 as well as an n<+> type InP substrate 1. Since an InGaAs photoabsorption layer 3a and an InP window layer 4a of planar type photodiodes are constructed by burying the above layers with the InP buried layer in this way, the foregoing incident light comes while spreading over the whole light receiving face. Then, the light responds sufficiently even to the incoming light where its intensity changes with time rapidly.

Title: Wireless monitoring device
Inventor: MURAMATSU TAKESHI
IPC: H04B17/00
Filed: 1989-05-16
Abstract: PURPOSE:To confirm whether or not the data is correctly sent from a wireless monitoring device to a receiver by providing a pseudo monitoring signal output section outputting a monitoring signal whose level is changed periodically and an RF amplifier section whose output strength can be switched in strength. CONSTITUTION:A monitoring signal from a device 5 is inputted to a monitoring signal input section 2 and binarized corresponding to the operating/stopping state. When monitor information is changed, a coding section 3 generates a communication packet, a transmission section 4 uses a high frequency being a VHF or UHF wave as a carrier to apply FM or AM modulation, thereby outputting the communication packet while being superimposed on the carrier. A pseudo monitoring signal output section 9 changes the output signal to the monitoring input section 2 every prescribed time and switches the transmission output of the RF amplifier section 10 from a strong output into a weak output while the monitoring signal is outputted to the monitoring section 2. Thus, the communication check in the unidirectional communication changing the monitoring input at a transmission side to confirm the change in the monitored value at the receiver side is implemented by having only to confirm the change in the monitor information at a reception side.

Title: Optical information recording and reproducing device
Inventor: OUCHIDA SHIGERU
IPC: G11B11/105
Filed: 1988-05-19
Abstract: PURPOSE:To contrive to miniaturize the titled device and to reduce its cost by providing a deflection split element having a diffraction grating whose grating direction is made different, on an optical path of a reflected light from an information recording medium. CONSTITUTION:A light beam which is reflected by a magneto-optical disk and transmitted through a polarized light beam splitter is made incident on the center between diffraction gratings 30a, 30b of a 2-split diffraction grating 30. The grating 30 is divided into two to the right and left centering around an optical axis, and the diffraction gratings 30a, 30b whose grating directions is made different by inclining each of them, for instance, by 45 deg. each by setting its center line as a boundary are formed on a grating substrate 30c. Accordingly, as for a deflection angle of the light beam which is made incident, the angles sensed by the gratings 30a, 30b are different, and in one grating 30a or 30b, the diffraction efficiency becomes high by a portion containing a (p) wave component, and on the other hand, in the other grating 30b or 30a, the diffraction efficiency becomes low. Therefore, by detecting a difference of both of them, the deflecting direction can be detected. According to this constitution, it becomes unnecessary to use complicated optical parts such as a lambda/2 plate and a Wollaston prism.
