Title: Tube for medical treatment
Inventor: OZASA HITOSHI
IPC: A61B1/06
Filed: 1994-08-31
Abstract: PURPOSE: To provide a medical treatment tube having a sufficient bending function as well as a small diameter by forming a groove on a tube body wall at a curved section, filling the groove with a photo-responsive material and selectively irradiating drive light /to the material with a curvature control means. CONSTITUTION: A tube body 1, when inserted in a body cavity and made to advance along an arbitrary direction, is bent toward the direction with a manual control section 3 under the observation of an endoscope image or the like. Consequently, each of light sources 10a and 10b laid in a control device 2 generates light of wavelength near maximum wavelength in the absorption spectrum of a photo-responsive polymeric material 5 buried in a groove 6, and the light is introduced to each of optical fibers 7a and 7b buried in the body 1 via the optical systems 9a and 9b of each optical fiber coupling. In this case, the quantity of light is controlled with a light source driver 11. According to this construction, light is irradiated to the photo-responsive polymeric material 5 for causing the expansion and shrinkage thereof, with the groove 6 acting as a curved section 14, thereby bending the tube body 1.

Abstract: PURPOSE: To hold a coaster in one hand to perform a lid operation by one finger and surely prevent the blocking of a seasoning by positioning a lid rocked between close position and casting position, and holding it in such a manner as to be operable. CONSTITUTION: The lid is formed of a rocking lid, and when it is in casting position, a slot 56 is exposed to the upper part over the top part of a caster body 12 to form a through passage for releasing a seasoning from the inner part. A series of projections 58 are integrally formed with an opening wall 28, and in casting position, they are positioned to the slot 56 of the lid 14 so as to be extended downward or inward of the open inner edge of the slot 56, and perfectly retreated from the thus-formed casting through passage. In the close position of the lid 14, the slop 56 is moved down on the projection 58, and the upper end of the slot 56 is engaged with the upper end of the projection.  The whole relative moving range of the projection 58 and the slot 56 forms an effective means for automatically cleaning the through passage formed by the slot 56 according to the rotating rocking between the two positions of the lid 14.

Abstract: PURPOSE:To cause a damping force in prescribed resonance regions near the primary and secondary resonance points of a suspension spring but reduce the damping force except in said regions, by providing a rotary member horizontally rotatable in contact with the peripheral surface of a piston rod. CONSTITUTION:When a large rotation is caused due to a prescribed resonance, one of the communication holes 41a, 41b of a rotary member 40 is opposed to the horizontal oil passage 9 of a piston rod 2 so that an upper chamber 4 and a lower chamber 5 communicate with each other. At that time, oil from the upper chamber 4 flows to an oil passage 6 through the communication hole 41a or 41b and a horizontal oil passage 9 and goes down to the lower chamber 6 through an oil passage 16 in a clamping metal 14, which communicates with the lower end, and an annular opening 17. Much of the oil in the upper chamber 4 flows to the lower chamber 6, as mentioned above, but does not flow to a damping mechanism, so that a damping force is reduced. The damping mechanism and the rotary member 40 are provided together to cause the damping force and reduce it only in desired regions, respectively.

Title: Automatic timing measuring method
Inventor: SEKINE MITSUO
IPC: H03K5/153
Filed: 1985-09-18
Abstract: PURPOSE:To shorten the timing check time by counting the voltage of a pulse applied to a counter in three voltage levels and judging a pulse waveform to be normal when counted values are equal to one another. CONSTITUTION:The voltage of a pulse waveform is inputted from an object 3 to be tested. A personal computer 1 instructs a counter 2 to measure the frequency at respective points of three preliminarily set measuring voltage levels. When all frequency measured results are equal to one another, the computer 1 judges the pulse waveform to be normal. If they are not equal to one together, the computer 1 judges the pulse waveform to be abnormal. Thus, the timing check time is shortened.

IPC: H01L21/82
Filed: 1990-08-03
Abstract: PURPOSE:To make it possible to reduce an unavailable region where no wiring exists by including a block shape comparison process which carries out a cell line-reduction process again when the length of cell line is longer than the shape of blocks and carries out a truck number-reduction process again when the number of trucks is more than the shape of blocks. CONSTITUTION:Comparison is made between a predicted shape of a block and a required shape of an input block where decision is made as to whether the block shape be changed or not. When it is decided to change the block shape, a cell line is reduced, if it calls for reduction in its cell line. When the change calls for the reduction in the number of blocks, the number of trucks is reduced. When it is decided to change no block shape, a detailed wiring route is decided. More specifically, attempts are made to move cell lines vertically in conformity to the number of wiring trucks existing in a channel which is a wiring region clamped by cell spacing and decide the coordinates of a wiring which connects signal terminals, thereby forming a final wiring pattern and deciding the block shape.
