Title: Variable compression ratio device for internal combustion engine
Inventor: KOJIMA KAZUHIRO
IPC: F02D19/08
Filed: 1993-02-19
Abstract: PURPOSE:To prevent any knocking in an engine and to improve fuel consumption by detecting the optimum compression ratio based on the blend rate of emulsion fuel and an engine operation load and setting the optimum ignition timing suitable for the compression ratio. CONSTITUTION:In an engine 1 having a variable compression ratio device 2, a compression ratio is switched to two stages of a high level and a low level through the feed of oil pressure from an oil pressure circuit 3. The oil pressure circuit 3 is controlled by means of a parameter being the number of revolutions of an engine, an engine load, and a blend rate of gasoline and methanol in fuel, based on the optimum compression ratio computed by an ECU 4. Further, after a compression ratio is switched by the variable compression ratio device 2, the optimum ignition timing is calculated by the ECU 4 from an engine load and an ignition timing signal is transmitted to an ignition coil 5. A blend rate of gasoline and alcohol in fuel is measured by a blend rate sensor 10 to input the result to the ECU 4. This constitution causes improvement of fuel consumption as knocking at an engine is prevented from occurring.

Title: Lifting pressure-reducing structure
Inventor: FUJII SHUNJI
IPC: E02D23/02
Filed: 1986-03-14
Abstract: PURPOSE:To reduce the weight of a structure by reducing the amount of a filler to be charged and also by lessening lifting pressures by providing recessed portions for the bottom of a structure to be set on a mound formed on the seabed ground. CONSTITUTION:Recessed portions 1 are formed in the bottom B of a structure and air is confined in the recessed portions 1 to form air chambers 11. On the boundary of the arm chambers 11, moving speeds of water particles are reduced, pressure gradient is bent on the recessed portions of the air chambers 11, and the lifting pressure P2 is reduced greatly in front of the chambers 11 and also reduced sparingly on the back side. By providing a plurality of air chambers 11, the pressure distribution is of a bent line with a plurality of bending points, and the lifting pressure P2 is more greatly reduced. Therefore, the amount of filler can be reduced, the size and weight of the structure can be reduced, and the structure can be set even on the ground of bad conditions.

Title: Mask for contact exposing
Inventor: FUJIWARA YASUHIDE
IPC: G03F1/68
Filed: 1989-03-08
Abstract: PURPOSE:To put the contact of the front surface of alight shielding material and a resist layer into point contact and to prevent sticking of both by imparting very small ruggedness on the front surface of the light shielding material of the mask. CONSTITUTION:A transparent substrate 1, such as glass plate, is put into a magnetron sputtering device or the like and, for example, a Cr film 2b is formed on the substrate 1. A negative bias is then impressed to the substrate 1 and a Cr film 2c is formed on the film 2b. Since the film 2c is sputtered again by a negative bias at this time, the Cr particles enlarge and the very small ruggedness 2a is formed on the front surface of the film 2c. Desired patterns 10 are then formed by a photoresist on the film 2c and after patterns P are formed of the layers 2c, 2b by etching, the patterns 10 are removed. The mask is thus produced.

Title: Burst gate pulse formation circuit
Inventor: KAWAI AKIHIRO
IPC: H04N9/455
Filed: 1981-04-13
Abstract: PURPOSE:To eliminate the variation of the width of a burst gate pulse outputted from a transistor (TR) by providing a selective circuit for outputting only a horizontal synchronizing pulse when there are both the horizontal synchronizing pulse and a flyback pulse simultaneously. CONSTITUTION:An alternative circuit 7 passes a synchronizing signal at the presence of the synchronizing signal and passes the leading pulse of a differentiated flyback signal at the absence of the synchronizing signal. A transistor 9 outputs a gate pulse according to the trailing pulse of a pulse obtained by differentiating the output of the circuit 7 by a differentiation circuit 8. Thus, even if the relative phase between the flyback pulse and horizontal sinchronizing signal is changed, the pulse width is not changed.
