Title: Optical reception level monitoring circuit
Inventor: NAKAMURA ICHIRO
IPC: H04B10/07
Filed: 1987-04-02
Abstract: PURPOSE:To monitor an accurate light reception level by connecting a resistor between a photodetector and an operational amplifier so as to reduce a malfunction. CONSTITUTION:A resistor 3 is connected between a photodetector 1 and an inverting input terminal of an operational amplifier 6 and a resistor 5 and a constant voltage diode 11 are connected in parallel between the inverting input terminal of the operational amplifier 6 and an output terminal. Since the light detection level monitoring circuit, when viewing an input of the operational amplifier 6, is in the series connection of the resistor 3 and the photodetector 1, the voltage amplification factor is small and the output offset voltage of the operational amplifier 6 is very small. Since the output voltage of the operational amplifier 6 is compared with a reference voltage source 7 by a comparator 8, whether or not a light of a prescribed light reception detection level is received is monitored depending on the output state of the comparator 8. Thus, the light reception level is monitored accurately with less malfunction.

Abstract: PURPOSE:To extend the life and avoid the erroneous emission by forming the surface layer portion of a cathode electrode out of a pair of electrodes with a metal cilicide and containing nitrogen in the discharge gas. CONSTITUTION:The surface layer portion of a cathode electrode 29 out of a pair of electrodes 29, 31 is formed with a metal cilicide (MSix) (M is metal, (x) is an integer), and nitrogen (N2) is contained in the discharge gas. Therefore, a metal cilicide with the low specific resistance constituting the surface layer portion of at least a cathode electrode 29 is spattered by the gas discharge, scattered in the gas space 21, then combined with N2 contained in the discharge gas, and generates a compound with the high specific resistance such as silicon nitride (SiNy) ((y) is an optional integer) and a nitride of metal silicide (MpSiqNr) ((p), (g), (r) are optional integers). Accordingly, a short circuit across electrodes can be suppressed, the nitrogen compound deposited between electrodes is transparent, thus the luminous brightness is not reduced, the life is extended, and the erroneous emission can be avoided.

Title: Bat for softball played with hard rubber ball
Inventor: NARUO TAKESHI
IPC: A63B102/18
Filed: 1997-03-14
Abstract: PROBLEM TO BE SOLVED: To improve a restitution characteristic by setting the natural frequency in the cylindrical direction of the hitting area of a bat for baseball played with hard rubber balls at specified Hz. SOLUTION: The natural frequency in the cylindrical direction of the hitting area 3 of a bat 1 for baseball played with hard rubber balls is set at 1450Hz or lower. The average thickness of the site 3a of the hitting area 3 that is 50 to 200mm from the head 2 of the bat is made higher than the average thickness of other sites 3b, 3c, and the natural frequency in the cylindrical direction is set at 1400Hz or lower. The site 3a whose average thickness is higher may be formed in the inside of the hitting area 3 of the bat 1 or in the outside thereof. By forming the bat 1 of an aluminum alloy whose natural frequency in the cylindrical direction thereof is low, the natural frequency can be made low and the restitution characteristic can be improved.  The formation of the thicker section 3a helps increase the effective mass of the bat without causing a loss in strength and improve the restitution characteristic.

Title: Curve detecting method of uoe steel pipe
Inventor: HIRANO OSAMU
IPC: G01B21/20
Filed: 1991-04-15
Abstract: PURPOSE:To detect a deformation generated actually in a pipe expansion process by measuring the extension of the pipe in the circumferential direction, so as to detect the curving amount of the pipe in the longitudinal direction. CONSTITUTION:When a UOE steel pipe is expanded, measuring parts X1 to X4 to indicated gage mark distances and measuring positions to find the variation of the length in the pipe circumferential direction are selected placing specific intervals in the circumferential direction. The lengths of these measuring positions are made equal primarily, and when they become to be X1+ X1, X2+ X2, X3+ X3, and X4+ X4 after the expansion, the curving of the pipe  L1 is proportional to the difference between  X1 and  X2. In this case, the  L1 indicates the difference between the straight line distance L1 selected at the measuring point X1 in the longitudinal direction and the measuring point X1 before and after the expansion. The same condition is applied to the curving  L2 to  L4 at the measuring positions X2 to X4, and the  L2 is proportional to the difference between  X2 and  X4 same as in the  L1. And the extension in the circumferntial direction can be measured at a high accuracy by a mechanical method or an electromagnetical method. In such a way, the curving in the longitudinal direction can be detected instantly on line, when the pipe expansion is processed.

CONSTITUTION:Inverted picture signals are inputted to an input terminal 1. Three picture elements adjacent to the picture signal train are set as A, B and C, and a picture element having a half picture element density corresponding to A and B of the three picture elements is set as D. The inputted picture signal is delayed by D type FFs 2, 3 and 4 by one clock each, outputs of A', B and C' are obtained at terminals 7, 8 and 9. Therefore, an output D' expressed by an expression 1 is obtained at the output of a NAND gate 5 and at the output of an AND gate 6 where A' and the output of the gate 5. As a result, since B can be saved whenever an black isolated point comes to the B by setting D to black when A is black, or even when A is white, by setting D to black if B is black and C is white, picture element density conversion is performed with lesser void and defacement.

Title: Method for contracting diameter of metallic superconductive wire rod
Inventor: II HIDEKI
IPC: B21C1/00
Filed: 1991-03-25
Abstract: PURPOSE:To obtain superconductive wire rod excellent in superconductive characteristics at a high yield by performing diameter contracting work under compressive stress acting on metallic superconductive wire rod in a high pressure atmosphere as all or part of the tensile stress is canceled. CONSTITUTION:When the diameter contracted part of the metallic supercon- conductive wire rod is kept under a high pressure atmosphere and the diameter is contracted by the high pressure atmosphere, the inner filament or the superconductive wire rod itself is not broken by the tensile stress because the tensile stress hardly acts on metallic superconductive wire rod. In this way, the superconductive wire rod excellent in superconductivity can be manufactured at a high yield.
