Title: Cooling structure for liquid crystal projector
Inventor: TAKAUCHI RYUJI
IPC: H05K7/20
Filed: 1998-10-20
Abstract: PROBLEM TO BE SOLVED: To provide a cooling structure for reducing temperature unevenness of a liquid crystal panel of a liquid crystal projector. SOLUTION: Liquid crystal panels 2r, 2g, 2b are arranged enclosing a prism 1 and polarizing plates 3r, 3g, 3b as sets. A cooling fan 10 is provided in the lower part of the prism 1, and the liquid crystal panels 2r, 2g, 2b, etc., are cooled. A U-shaped groove-like cooling air plate 4 is installed between one ridgeline on an end face in an upper part of the prism 1 and an end face of, e.g. the polarizing plate 3g counter thereto. Cooling air f1 from the cooling fan 10, provided in the lower part of the prism 1 flows upwardly on an emission face of the liquid crystal panel 2g, etc., and changes flow to downward direction by the U-shaped groove-like cooling air plate 4, to become cooling air f3 flowing downward on the emission face of the liquid crystal panel 2g, etc.  Since the flow of cooling air for cooling the liquid crystal panel becomes reverse in direction between the emission side and a reception side of the liquid crystal panel, temperature unevenness of the liquid crystal panels 2r, 2g, 2b is relayed.

Abstract: PURPOSE:To prevent deformation of a pad and enable improved recording/ reproduction to be performed by making the pad which presses a tape to the magnetic head of three layers of stiffness-high-low-high, or of an expansion and contraction member end changing both sides with the rib of the casing. CONSTITUTION:A rectangular parallelopiped pad is fixed to a rib 21 of a casing 1. The rib 21 is a box type with the front surface and the upper part being open and has a protrusion for preventing falling 21b on the inner surface. A pad 22 consists of three layers of stiffness (high, low, high) 23a/23b/23c and is fixed to the rib 21 so that three layers are aligned in running direction of a tape T. When a head enters, it is not deformed due to friction with the tape and an improved pressing is retained, thus enabling an improved recording/ reproduction to be performed. Formation of the pad 22 with a member 24 having expansion and contraction property is similarly valid.

Filed: 1995-10-23
Abstract: PROBLEM TO BE SOLVED: To improve productivity by reducing the number of times for detecting a mirror die located around a wafer and a die which is similar to the mirror die. SOLUTION: When a mirror die 3 is detected within an inversion range 11, a first die 2 in a next row is detected after moving in Y direction by one pitch. When the first die 3 is not a mirror die, the die 2 is successively detected and picked up toward the direction of the outer diameter in X direction. Then, when the mirror die 3 is detected, the inner die 3 being adjacent to the above first die is detected and picked up after inversion and then dies are successively detected and picked up due to the inverted move in X direction. When the above first die is the mirror die 3, the traveling direction in X direction is changed for successive detection. Otherwise, the die is picked up.
