Abstract: PURPOSE: To provide a connection construction of high fatigue strength, corrosion resistance, and economic efficiency, by placing concrete between a pair of precast concrete members in which connecting U-shaped reinforcement and reinforcing/connecting reinforcement are projectingly provided on the end faces. CONSTITUTION: A precast concrete member 2 is previously manufactured in a factory so that connecting U-shaped reinforcements 03 projecting the U-shaped ends from the center parts of both end faces in the axial direction and reinforcing/connecting reinforcements 1, 1 projecting shorter than the projecting length of the U-shaped reinforcement 03 from the upper parts and the lower parts of both end faces are set as cores. At jobsite, a pair of the precast concrete members 2, 2 are arranged so that their front and rear end faces are separated from each other by a fixed distance and the connecting U-shaped reinforcements 03, 03 are jointly formed into a connection loop, and cast-in-place concrete 3 is placed between the front and rear end faces.  By connecting together the precast concrete members 2, 2 in this way, the reinforcement quantity extending in the front and rear directions at the section of the construction joint 05 of the cast-in place concrete 3 is remarkably increased.

IPC: F25C1/10
Filed: 1997-01-30
Abstract: PROBLEM TO BE SOLVED: To read the change point to a steady state of a pulse signal and to positively detect that an ice-makign tray is in a horizontal state by outputting a pulse signal after the ice-making tray stops in a horizontal state when a drive motor rotates reversely. SOLUTION: A control means 3 detects the completion of ice releasing and rotates a drive motor 2 reversely and returns an ice-making tray 1 to a horizontal state. An ice-making tray drive means 4 is not linked to the drive motor 2 due to the returning operation, the returning operation of the ice-makign tray 1 is also completed at this point and the ice-making tray 1 stands still in a horizontal state. Then, the drive motor 2 continues to be driven, and a pulse signal is outputted to the control circuit 3 again from a pulse-generating means 6 in an overrun region where a delay drive means 5 operates in linking with the drive motor 2. Then, the control means 3 reads the falling of the pulse signal and detects that the ice-making tray is in a horizontal state and at the same time stops the drive motor 2 for returning to the initial state.

Title: Confocal scanning type microscope
Inventor: TERADA HIROTOSHI
IPC: G02B21/00
Filed: 1994-03-03
Abstract: PURPOSE:To provide a confocal scanning type microscope which does not require the constitution of a confocal optical system requiring accurate alignment in the case of changing the wavelength of irradiating light. CONSTITUTION:The optical system of the confocal scanning type microscope is constituted without arranging spectroscopic parts in the confocal optical system from the minute spot of the irradiation light on a sample 900 to a diaphragm 500 for cutting stray light. The spectroscopic processing of generated light on the sample 900 is executed after the generated light passes through the confocal optical system so as to completely reduce the stray light. As a result, observation is executed by easy change, that is, by changing the wavelength of the irradiation light without changing the constitution of the confocal optical system requiring accurate adjustment.

Title: Optomagnetic recording medium
Inventor: ENDOU KIYONOBU
IPC: G03G19/00
Filed: 1983-03-03
Abstract: PURPOSE:To form a magnetic recording medium with which a reproduced signal fluctuates less without decreasing an SN ratio by providing a reflection layer for laser light for reproduction between a recording layer and a transfer layer. CONSTITUTION:Laser light A for writing is condensed and made incident from an antireflection layer 6 by a lens to a recording layer 2 through the layer 6. The light A is absorbed in the layer 2 and is converted to heat energy, then the direction of a magnetic domain is inverted by an ambient magnetic field or external bias magnetic field and information is recorded. When the signal information is written by the direction of the magnetic domain in the highly sensitized layer 2, the direction of the magnetic domain in a transfer layer 3 is conformed to the direction of the magnetic domain in the layer 2 by the influence of a magnetic field loop B, by which the written information signal is transferred. Laser light C for reading out and reproduction is condensed from a substrate 1 side by a lens into a spot shape and is imaged on the layer 3. The layer 3 has a high Curie temp. and is not incorporated with the constitution for improving sensitivity and therefore the light C having substantially strong power can be applied thereto. The light C is reflected by the layer 4 and the much larger rotating angle in the plane of polarization is obtd. by the synergistic effect of the Kerr effect and Faraday effect.

IPC: B24C1/04
Filed: 1989-02-14
Abstract: PURPOSE:To reduce the diffusion of a jet, to concentrate energy in the progressing direction and to increase the efficiency in grinding and cutting by providing a Coanda spiral flow forming nozzle freely turnably and movably. CONSTITUTION:A pressurizing water as for a pressurizing fluid is led into a main cylinder 2 from a slit 3 in a Coanda spiral flow forming nozzle. Thus the kinetic vector of the pressurizing water and the kinetic vector of the fluid of the water and air, etc., fed from a leading inlet port 6 are compounded and a spiral motion 10 is formed. This spiral motion 10 brings the concentration in the progressing axial direction of the fluid speed, forming a high speed concentrated flow. Also due to a Coanda layer being formed inside the main cylinder 2 the internal wall wear of the nozzle is restrained even in case of mixing a hard cutting particle. Also in case of mixing particles the dispersion is uniformized.

Title: Optical device
Inventor: MASUDA TAKESHI
IPC: G02B7/02
Filed: 1990-02-15
Abstract: PURPOSE:To constitute this optical device in such a manner that the position of a detector aligns to the position of the focus formed by lenses and mirrors by using such a material which has the coefft. of linear expansion nearly zero in the optical axis directions as the material of a lens barrel and adopting the structure to support this lens barrel only at one point. CONSTITUTION:The coefft. of linear expansion in the optical axis direction of the lens barrel 4a is made nearly to zero by using CFRP oriented with fibers 9 only in the one direction parallel with an optical axis 7 as the material of the lens barrel 4a. The detector 1 is set in the position of the focus formed by the lenses and mirrors 2 by setting the position of a supporting frame 3 and the lens barrel 4a and further the lens barrel 4a is supported only at one point by a supporting structure 5 and is thereby fixed to an artificial satellite 6. The thermal deformation of the lens barrel is, therefore, substantially not generated in the optical axis direction if the use environmental temperature is changed. Moreover, the deformation and dimensional change of the mounting surface of the artificial satellite are hardly transmitted to the lens barrel even if there are such deformation and dimensional change. The position of the detector is always aligned to the position of the focus formed by the lenses and mirrors in this way.
