Title: 2-cycle engine
Inventor: MOTOYAMA TAKESHI
IPC: F02B75/02
Filed: 1985-07-18
Abstract: PURPOSE:To relieve a sudden rise in a pressure and to reduce a fluctuation in torque due to irregular combustion, by a method wherein an on-off valve is located in a bypass passage running from the upper area of cylinder to an exhaust passage, and the valve is opened in a middle and low speed range and a middle and low load range. CONSTITUTION:A bypass passage 10 is so formed as to extend from a position above an exhaust port 8 in a cylinder 1 to the middle of an exhaust passage 9. An electromagnetic valve 11 is located to the middle of a bypass passage 10, and the bypass passage 10 is opened and closed by a valve part 11a of the electromagnetic valve. In which case, operation of the electromagnetic valve 11 is controlled depending upon the rotation speed or the load of an engine, and is so constituted as to be opened at a middle and low speed range and a middle and low load range, and closed at a high speed range and a high load range. Since the upper range of the cylinder 1 is brought into a state in that it is communicated with an exhaust passage 9 through the bypass passage 10 at a middle and low speed range and a middle and low load range, a sudden rise in a pressure during a compression stroke and an expansion stroke is leaked through the bypass passage 10, and this enables relief of the sudden rise in the pressure.

Title: Heat sink
Inventor: TSUSHIMA EIKI
IPC: H01L23/373
Filed: 1996-05-29
Abstract: PROBLEM TO BE SOLVED: To enable high temperature solder joint and sufficiently reduce generation of a thermal stress due to temperature change at the times of adhering and using by a method wherein both front and back surface of a unidirectional carbon fiber reinforcing composite material are covered with a specific thin- plate-like metal member by diffusion joint. SOLUTION: In a flat plate 1 of a unidirectional carbon fiber reinforcing composite material in which a carbon fiber is arranged in a thickness direction, by using the flat plate 1 in which thermal conductivity in a length direction of the carbon fiber is sufficiently high, the thermal conductivity in a thickness direction of the flat plate 1 can be increased more than metals such as silver, copper, aluminum, etc. In particular, both the front and back surfaces of the flat plate 1 are structured so as to be covered with a thin-plate-like metal member 2 of a thickness about 50μm or less by diffusion joint. Thereby, as thermal conductivity in a thickness direction is high, radiation property is very excellent.  Further, as thermal expansively and elasticity coefficient in a width direction are small, thermal stress generation due to temperature change is small, and adverse influences on a semiconductor like separation do not occur.

Title: Electrostatic recording system
Inventor: SAITOU SUSUMU
IPC: G03G15/05
Filed: 1983-08-30
Abstract: PURPOSE:To enable the prevention of abnormal black dots or the like by applying a voltage smaller than and the same in the polarity as the recording voltage to a recording needle left with no recording voltage applied thereto at least adjacent to any one while the recording voltage is being applied thereto. CONSTITUTION:When a block is selected from the group A or B, a recording voltage of Vs, for example, -280V is applied selectively to recording needles 1 of all blocks in the group A or B according to image information. At the same time, a voltage Vb smaller than and the same in the polarity as the recording voltage, for example, an auxiliary pulse of -150V allowing the recording of no electrostatic latent image is applied to all the recording needles in the group B or A and to all recording needles left with no recording voltage applied in the group A or B. Thus, the potential difference Vb-Vs becomes small enough to cause no discharge between the recording needles thereby preventing the generation of uneven recording density and abnormal black dots as well as a trouble of disabling black dot recording. This also enables stable recording of a pattern inverting from white to black one dot apart.

Title: Dropout compensation circuit
Inventor: KURODA KAZUO
IPC: H04N5/94
Filed: 1980-11-11
Abstract: PURPOSE:To avoid the delay in compensating operation and to achieve compensation of excellent dropout, by using a sampling pulse synchronized with a carrier wave for the output of a wave detection circiuit at all times and achieving the detected output through sample-holding. CONSTITUTION:The actual dropout generating period is detected by a monostable multivibrator MMV9 of the prestage and a detection signal (e) is produced, and the next MMV10 is triggered at the tail end ridge of this detection signal (e) to produce a delay signal of a prescribed period. The production of a sampling pulse (d) is inhibited by closing an AND gate 11 for the period of presence of the outputs (e), (f) of the MMVs 9, 10, and the transmission of the sampling pulse (d) to a sample holding circuit 4 is interrupted. Thus, the dropout and the distortion of waveform for a prescribed period after that are stored and compensated with a sampling level immediately before the production of the dropout.
