Title: Semiconductor integrated circuit
Inventor: MATSUSHIMA JUNKO
IPC: H01L27/10
Filed: 1990-08-10
Abstract: PURPOSE:To prevent the deterioration of signals on bit lines in high-speed operation by transferring signals through a twisted pair of bit lines formed in upper and lower layers on a substrate. CONSTITUTION:Upper bit lines 1 and 3 are formed above lower bit lines 2 and 4 on a substrate 11. Bit lines are connected through deviated contact holes 5 to form a pair of bit lines and a twisted pair of inverse bit lines. Bit line 201 and inverse bit lines 202 are connected to a sense amplifier 230 to amplify the very low voltage between the two lines. This realizes a smaller memory area than with a single-layer bit line structure and prevents the deterioration of signals on bit lines in high-speed operation.

Title: Variable brightness difference control circuit for polymorphic oscilloscope
Inventor: MORINO ATSUMI
IPC: G01R13/28
Filed: 1987-08-29
Abstract: PURPOSE:To facilitate waveform observing operation by giving a brightness difference to polymarphic display bright lines displayed on the cathode-ray tube of the polymarphic oscilloscope, and setting the brightness difference optionally. CONSTITUTION:Two polymorphic signals of reference channels CH1 and CH2 to be measured are controlled by a channel switching circuit D, and amplified by a mixing amplifier C3 and an amplifier C4, and the vertical deflecting plate of the CRT is driven. The output 1 of the reference channel CH1 of this channel switching circuit D is adjusted by a voltage adjuster E and applied to a brightness difference generating circuit G. When a brightness difference on-off circuit is turned on, the output of the brightness difference generating circuit G is applied to an unblanking amplifying circuit H. Consequently, a waveform is displayed with high brightness in the display period of the reference channel CH1 and low brightness in the display period of the channel 2. The brightness difference is varied through a variable resistor VR1. Consequently, the waveform is discriminated by one touch, so the waveform observing operation is facilitated.

Title: Suspension structure for rear two-axle car
Inventor: KATSUTA HIDEAKI
IPC: B60G21/067
Filed: 1993-08-31
Abstract: PURPOSE:To prevent the reduction in axle load of a rear driving axle and stabilize traveling state by providing a flow rate control means for making easy for compressed air to flow from an air spring for supporting a rear driven axle to an air spring for supporting the rear driving axle. CONSTITUTION:When a rear driven rear wheel 11 runs on a difference in level of a road to a front driving rear wheel 6, the axle load of a rear driving axle 7 is apt to reduce. In a flow rate control means, a bypass pipe 22 is formed with a diameter larger than that of a communicating pipe 18, and the check valve 23 of the bypass pipe 22 is provided to carry compressed air to a first air spring 5 side. Since the compressed air quickly flows to extend the first air spring 5, thus, the rear driving axle 7 is displaced down to cope with a reduction in axle load. On the other hand, since the compressed air is difficult to flow on a second spring 9 side, it can be suppressed that the first air spring 5 is compressed by the reaction by the driving torque of the front driving rear wheel 6 at retreating a vehicle.

Title: Cylinder drum for magnetic recording and reproducing device
Inventor: INOUE TAKAO
IPC: G11B5/52
Filed: 1986-09-11
Abstract: PURPOSE:To obviate the significant impairment of workability while enhancing wear resistance and other desirable characteristics by using an aluminum-silicon alloy in which the content of silicon, expressed by weight %, is in a 10-14% range. CONSTITUTION:Both the specific abrasion wear and coefft. of linear expansion decrease and the alloy has the characteristics desirable as the stock for a cylinder drum with an increase in the content of the silicon. On the other hand, the workability is increasingly poorer with an increase in the silicon content. The silicon content is, therefore, determined in the 10-14% range by taking the specific abrasion wear, coefft. of linear expansion and workability into account. The wear resistance and the sliding characteristic with a magnetic tape are thereby improved and the coefft. of linear expansion is decreased; therefore, the errors by the wear of the cylinder drum are decreased and the change in the diameter of the cylinder drum arising from a temp. change is decreased as well.
