Title: Photoionization mass spectrometer
Inventor: OSABE SATOSHI
IPC: H01J37/252
Filed: 1997-05-29
Abstract: PROBLEM TO BE SOLVED: To improve the detecting efficiency by repeating a process for making the laser beam focused on a sample by a first optical element, passed through a second optical element, reflected by a third optical element to be deflected in a direction vertical to an optical axis, further passed through the second and first optical elements, and reflected and deflected by a fourth optical element several times, and then discharging the laser beam to the outside rather than through the optical element. SOLUTION: A laser beam 7 from a laser 6 is entered in parallel with an optical axis of a lens 11, focused on a sample 1, returned to an almost parallel optical path by a lens 12, deflected and reflected in a direction vertical to the optical axis by a flat reflection mirror in which two sheets of mirrors are crossed to each other, and focused on the sample 1 by the lens 12. The laser beam is returned to an almost parallel beam by the lens 11, deflected and reflected by a flat reflection mirror 10, and then entered into the lens 11. This process is repeated. The pulses of the laser beam 7 are either overlapped on the sample 1 or the beams are closed to each other. As a result, the intensity of light is increased, or a diameter of the laser beam is increased, which improve the ionization efficiency or the laser dose rate.

Abstract: PURPOSE:To simplify the control system of a circuit, and also, to reduce the memory capacity for storing the information by converting luminance information of M mode information stored in a display memory to position information and outputting A mode information. CONSTITUTION:When for instance, M mode information stored in an M mode Doppler information memory 14 is read out by a write enable signal 12a of the memory control circuit 12, luminance information 14a of an M mode display is outputted, and inputted to an adding circuit 16. Also, the luminance information is inputted to an A mode display circuit 18, as well, and in the circuit, by control input of a display control signal 12b, position information brought to A mode display can be selected arbitrarily in the information of an M mode display. As a result, the luminance information is converted to the selected position information, and converted as A mode information to an A mode shape 18a of a prescribed time phase. Accordingly, by only the display memory capacity for an M mode, the A mode information can be obtained. Also, with respect to a circuit of a control system, as well, the control of only a display memory for an M mode is enough, and the control circuit can be simplified.

Title: Protecting tube and thermocouple using it
Inventor: AMAMIYA MITSUAKI
IPC: G01K7/02
Filed: 1998-05-21
Abstract: PROBLEM TO BE SOLVED: To prevent a short circuit generated between element wires constituting a thermocouple even in an atmosphere in which a conductive dust such as metal flutters by lengthening the shortest distance of a No.1 hole and a No.n hole along an edge surface of a protecting tube than a specific length. SOLUTION: This protecting tube for a thermocouple accommodating two element wires is provided with a stepped portion 6 at an intermediate area of holes 3a, 3b into which the thermocouple is inserted or drawn at an end. Thereby, the shortest distance of a first hole 3a and a second hole 3b can be lengthened than L-R1 -R2 (L represents a space between a center of the hole 3a and a center of the hole 3b and R1 and R2 represent a radius of the holes 3a, 3b, respectively). Accordingly, a distance along a surface of the two holes 3a, 3b can have a longer distance than that of a usual protecting tube. Therefore, a short circuit between the element wire passed through the hole 3a and the element wire passed through the hole 3b can be prevented even in an atmosphere in which a conductive dust such as metal and carbon flutters.

Title: Ball screw feeder
Inventor: FUKUYAMA YASUNORI
IPC: F16H25/24
Filed: 1986-06-18
Abstract: PURPOSE:To enable the positioning with a quite high accuracy by constructing such that a nut and a working member are connected through a resilient coupling member having the board face directing toward the moving direction of the working member. CONSTITUTION:Since a nut 6 and a working member (moving table) 1 are connected through a coupling member 7 with the board face thereof directing toward the moving direction of the working member, the working member follows reliably to the motion of said nut 6 in the feeding direction. If the advance-straight performance is not maintained in a threaded shaft 4 or a guide rod 3, the shift of said advance-straight performance is absorbed by the coupling board 7, thereby an excessive force does not function onto a fitting section between a ball screw and the nut 6 thus enabling a smooth traveling of the working member. Consequently, the backlash due to the abrasion does not increase even when this device is functioned repeatedly.

Filed: 1977-11-24
Abstract: PURPOSE: To enable obtaining of extremely small icecrushing resistance of a frozen sea ship at linear sailing time and of sufficient turning performance at turning time, and of transportation of articles or the like in frozen sea icy waters.  
     CONSTITUTION: There are provided projections 2 at the stem of the hull 1 of a frozen sea ship and ballast tanks 4a to 4c at the stem, sides of hold 3, bottom, and stern. The draft of the hull can be altered between linear draft WL 1  and turning draft WL 2  by means of the ballast tanks 4a to 4c, and the projections 2 make contact with ice plates on the sea surface at the turning draft WL 2  time. Accordingly, when the hull 1 is turned in the icy waters, it retains the turning draft WL 2  to destroy the ice plates via the projections 2 to form open sea surface of broader width than the width of the ship in the amount of the projections 2 so as to thereby easily steer the ship. When the ship sails linearly in non-icy waters or icy waters, the linear draft WL 1  is retained so as to dispose the projects 2 above the  sea surface.

Filed: 1986-06-17
Abstract: PURPOSE:To obtain a copper alloy causing no deterioration in strength at a soldered joint even after long use and further free from stress corrosion cracking, by providing a composition in which respective contents of Sn, P, Zn, Mn, and O2 are specified and which has the balance Cu. CONSTITUTION:The copper alloy for electronic and electrical equipments has a composition consisting of, by weight ratio, 2-8% Sn, <=0.01% P, 0.05-0.75% Zn, 0.02-0.2% Mn, <=20ppm O2, and the balance Cu. Since exfoliation at a soldered joint is caused by the diffusion of P in phosphor bronze into the soldered joint and attendant concentration, P content in phosphor bronze is reduced as compared with conventional one and further Zn and Mn are added so as to inhibit the above-mentioned harmful action in this invention. The copper alloy of this invention is excellent in solder strength and adhesive strength to thin or solder plating and, moreover, this copper alloy produces remarkable effects from the view point of electronic and electrical industry without causing circuit faults even after long use.
