Title: Recording medium
Inventor: ONUKI SATORU
IPC: G11B7/24067
Filed: 2000-02-01
Abstract: PROBLEM TO BE SOLVED: To provide an optical recording medium in which warpage of the medium caused by changes in the environmental temperature can be decreased. SOLUTION: The magneto-optical recording medium 100 has a laminated body 10 on one face of a substrate 1 and has a warpage preventing film 9 on the other face. At least, one of the structural material or the film thickness of the warpage preventing film 9 is decided in such a manner that the product of the Young's modulus and the film thickness of the warpage preventing film 9 is almost equal to the total sum of the products of the Young's modulus and the film thickness of the respective layers 2 to 8 which constitute the laminated body 10. Thus, the stress added to the medium is balanced on both sides of the substrate 1 by a bi-metal effect and the warpage of the disk caused by changes in the environmental temperature is significantly decreased. This method is extremely suitable for an optical recording medium which uses a thin substrate having low rigidity.

IPC: A63F7/02
Filed: 2000-02-14
Abstract: PROBLEM TO BE SOLVED: To provide a game machine which can heighten player's interest in a game by devising a display mode upon temporary stopping. SOLUTION: A variable displays game is temporarily stepped at a special symbol layout of '1, 1, 9' based on a prescribed game condition.

Filed: 2000-02-15
Abstract: PROBLEM TO BE SOLVED: To provide a reception state display device for more easily finding the best point of the direction of a reception antenna for simultaneously receiving radio waves from two earth satellites. SOLUTION: Corresponding to read set contents, a power supply voltage is set so as to supply the reception signals of specified polarized waves from the reception antenna (S210-S240), the signal level LV1 of a specified channel is read for the satellite A (S250-S270) and then, the signal level LV2 of the specified channel is similarly read for the satellite B (S28O-S300). Based on both signal levels LV1 and LV2, a value for which the difference of both signal levels is subtracted from the added value of both signal levels is obtained as a display level LVD (=|LV1+LV2|-|LV1-LV2|) (S310) and it is displayed on a display device 17 together with the previously read set contents (S320). By adjusting the reception antenna to the direction where the display level LVD becomes a peak, the radio waves from both satellites A and B are excellently received.

Title: Traveling control device
Inventor: TAMURA MINORU
IPC: B60W30/09
Filed: 2000-02-21
Abstract: PROBLEM TO BE SOLVED: To prevent the generation of accelerating condition by the follow-up traveling control or the accelerating operation by a driver in the condition that the brake preload is generated in the case of performing both of the brake control for generating the brake preload before operating a brake and the follow-up traveling control for maintaining an inter-vehicle distance at the predetermined inter-vehicle distance. SOLUTION: A target deceleration GB is computed on the basis of the own- car speed Vm and an inter-vehicle distance L. When the target deceleration GB exceeds the set value GBS, a control device discriminates the condition that the brake preload is required, and sets the brake preload PPB when an acceleration pedal is released, and generates the corresponding brake pressure so as to start the preview brake control. In this condition, when the control device discriminates the condition for starting the acceleration control with the follow-up traveling control, the control unit prohibits the start of the acceleration control, and start the acceleration control after the brake preload is released. In this case, when acceleration is operated by a driver, the brake preload is released.
