Title: Hand carrier for bottle
Inventor: YAMAMOTO MASAHIRO
IPC: B65D71/48
Filed: 1997-02-13
Abstract: PROBLEM TO BE SOLVED: To raise a bottle by a carrying part provided on face-like parts by hooking a crown cap of the bottle with a cap insertion port and also interposing it between the face-like parts. SOLUTION: A bottle is inserted from a bottle insertion port 9 of the hand carrier for bottles from a head side with a crown cap put on and pushed in until the crown cap comes against sides of carrying parts 2, 2' of the cap insertion port 3. At the time of pushing in, door-like pieces 6, 7 are opened by a cut 5 with both sides of the cut 5 as hinges, but restoring force restoring to an original shape also functions. The restoring force causes the door-like parts 6, 7 to be kept inserted at a lower end position of the crown cap of the bottle immediately after the bottle has been completely inserted. As a result, the crown cap is held while being interposed between the door-like pieces 6, 7 and sides of the carrying parts 2, 2' of the cap insertion port 3.  When the carrier is to be held in hand, the carrying part 2' on the back side is folded through a hole of the carrying part 2 on the front side, thereby making stuck faces difficult to open.

Abstract: PROBLEM TO BE SOLVED: To obtain a video signal with excellent S/N resulting from enhancing the effect of smear and a wide dynamic range in a video signal processing unit that synthesizes video signals with different exposure ratios in a same scene. SOLUTION: A smear detection means 21 uses a standard exposure video signal 4 after gain adjustment, a nonstandard exposure video signal 6, and an exposure ratio signal 12 to detect a mean value of smear of one image pattern in a vertical direction. The detected smear mean value is given to a subtractor 11 as a smear detection means output 28. The subtractor 11 subtracts the smear detection means output 28 from a synthesized video signal 8. An output of the subtractor 11 is a video signal with a wide dynamic and an excellent S/N that is less affected by a smear component. Or the processing unit may be configured such that the smear detection means output 28 may be subtracted at an input side of a video signal synthesis means 9.

Title: Tunnel structure
Inventor: HIRAKAWA HARUO
IPC: E21F1/00
Filed: 1992-02-17
Abstract: PURPOSE:To substantially reduce pressure fluctuations in tunnel by making the cross-sectional area of a tunnel extending over a specified distance from the inlet or the outlet of a normal tunnel considerably larger than that of the normal tunnel. CONSTITUTION:At the inlet and outlet of a normal tunnel 3, large tunnels 2 having a larger cross-sectional area than that of the normal tunnel are provided. The length L of the tunnel 2 is determined by dividing a value obtained by multiplying the length of a train 1 by the speed of sound, by a value obtained by subtracting a maximum business operating speed of the train from the speed of sound. When the train 1 enters the tunnel 3, a negative pressure expansion wave generated when the tail of the train enters the inlet of the tunnel 2 is propagated at the speed of sound. The expansion wave and a positive pressure compression wave generated when the train enters the tunnel 3 are overlapped to damp the magnitude of the compression wave. Besides, a hood of large cross-sectional area can be mounted instead of the tunnel 2, or a negative pressure generating device can be provided to reduce the pressure of the compression wave. Thus, pressure fluctuations in tunnel generated when a train train runs at high speed can be substantially reduced, and the reliability of the strength of a train can be improved.

IPC: H05H1/34
Filed: 1990-02-08
Abstract: PURPOSE:To omit a junction box and to provide a torch hose which is simple, small and light by providing only the electric cable affording a main plasma power source between a torch and a plasma power source device. CONSTITUTION:An electrode controller 12 impresses a main plasma voltage between a material 9 to be cut and a discharge electrode 1 when air flows through a stop valve 6 to a tip 2. The main plasma power source of the electrode 1 is, therefore, connected while the air is kept injected from an air injection port of the tip 2. A piezoelectric unit 5 impresses a high voltage between the electrode 1 and the tip 2 after opening of the stop valve 6 when a start button 7 is pushed; therefore, the tip 2 ejects the air and the main plasma power source is connected to the electrode 1 when this high voltage is impressed to the tip. A discharge spark is accordingly generated between the electrode 1 and the tip 2 by the high voltage of the piezoelectric unit 5 and the main plasma discharge is generated between the electrode and the material 9 to be cut in this way. The presence of the electric cable 43B between the torch 40 and the plasma power source device 30 is, therefore, merely necessitated.

Abstract: PURPOSE:To project one light beam from a semiconductor laser while expanding or reducing its width beam and to reduce the size and cost of light beam shaping constitution by providing one prism which has a refracting and a reflecting surface at a certain angle and setting its angle of incidence and refractive index. CONSTITUTION:The projection light of the semiconductor laser 21 is made into a parallel light beam 23 by a collimator lens 22 and incident on a prism 24 as a beam shaping optical system. The prism 24 has the refracting surface 24a and reflecting surface 24 opposite each other at an angle dtheta and when the light beam 23 is incident on the refracting surface 24a at an angle theta1 of incidence, its refracted light is refracted at an angle theta2 of projection, emitted into the prism, and reflected by the reflecting surface 24b to strike on the refracting surface 24a at an angle theta3 of incidence from the prism side. Then, the light beam 26 projected from the refracting surface 24a become perpendicular to the incident light beam 23. In this case, the refractive index (n), incidence angle theta1, and angle dtheta of the prism are set to certain values and thus the optical paths of the incident light and projection light are formed at right angles to each other, thereby reducing the size of the device.
