Title: Heat-dissipating pressure-sensitive adhesive sheet and manufacture thereof
Inventor: TANAHASHI HIDEAKI
IPC: C09J7/02
Filed: 2000-01-25
Abstract: PROBLEM TO BE SOLVED: To make a sticky face hardly allowing inclusion of air and thereby obtaining a specified bonding strength when an adhesive is attached to a rigid body by forming strip grooves or projecting strips at least on either of front and rear faces. SOLUTION: A plurality of strip grooves 2 are formed on the front face of a heat- dissipating pressure-sensitive adhesive sheet S whose front and rear faces are formed as sticky faces 1a, 1b. When the heat-dissipating pressure-sensitive adhesive sheet S is provided between the rear face of a panel 11 and a heat-dissipating plate 12, the sticky face 1a is attached to the rear face of the panel 11. In this case, since the strip grooves 2 are formed on the sticky face 1a, the sticky face 1a is narrow widthwise so that air hardly finds its way into an area between the rear face of the panel 11 and the sticky face 1a. Even when the air is entrapped in the area, it is easily discharged into the strip grooves 2 by pressing the heat-dissipating plate 12 from above.  Further, even when the temperature of the panel 11 or the like is increased, a heat-dissipating effect is achieved by the venting of the heated air upward through the strip grooves 2 by bonding the heat-dissipating pressure-sensitive adhesive sheet S in such a way that the lengthwise direction of the strip grooves 2 is vertical.

Title: Boost quantity variable equalizer for measuring dvd jitter
Inventor: MASUDA AKIHIKO
IPC: G01R29/02
Filed: 2000-02-01
Abstract: PROBLEM TO BE SOLVED: To surely measure jitter of an HF signal by surely locking a PLL clock regeneration circuit provided to a jitter measurement device of one input, even if the HF signal comes from an optical DVD. SOLUTION: An equalizer consists of 1st and 2nd delay lines DL1, DL2 with a delay amount of 2T, an operational amplifier OP, variable resistors R1-R4, and a fixed resistor R5. Adjustment of at least one of the variable resistors R1-R4 can change an output voltage from the operational amplifier OP, thereby continuously adjusting a boost amount. Since the boost amount can optionally be adjusted from an HF signal in an optional DVD system, the PLL clock recovery circuit provided to a jitter measurement device main body with one input can be locked and jitter can surely be measured. Furthermore, since the measurement device consists of only analog circuits, the device can be reduced in size and noise generation and deterioration in time base resolution performance can be prevented.
