IPC: F02B29/04
Filed: 1986-07-14
Abstract: PURPOSE:To prevent the occurrence of the knocking, by using one of the two air-intake valves as a normally working, air-intake valve connected to a supercharger and delaying the valve-closed-period to the first half of the compression stroke, thereby returning a portion of compressed air to a by-pass pipe with a cooler. CONSTITUTION:A working chamber 4 of each cylinder is provided with two air-intake valves 10 and 11. One (10) of the two air-intake valves is connected to a supercharger 6 via an intercooler 9. The closing timing of this air-intake valve 10 is set at the normal timing. The closing timing of the other air-intake valve 11 is largely delayed and is set at 100-120 deg. after the bottom dead center. With this contrivance, in the compression stroke, a portion of the intake-air is returned to a supply-air return passage 13, cooled in a supply-air cooler 14, and then returned to the normal supply-air passage 12. Accordingly, the air-intake valve 11 functions as an intake-air return valve as well.

Title: Semiconductor package and its manufacture
Inventor: YOSHIDA TOKUO
IPC: H01L23/50
Filed: 1994-07-15
Abstract: PURPOSE:To prevent irregularity of bonding strength due to difference of heat capacities, and improve the reliability of junctions of outer leads and circuit terminals, by making the heat capacities of junction parts of the circuit terminals and the outer leads equal. CONSTITUTION:The difference in surface area between a circuit terminal 3 on a board 1 and an outer lead 4 is set as the difference of heat capacity. The inverse heat capacity difference is imparted to the outer lead 4 which is connected with each circuit terminal 3. Thereby the heat capacity of each junction in the case of bonding is made equal. A wide outer lead 4 is bonded to a circuit terminal 3 whose heat capacity is small because the surface area is small. A narrow outer lead from which heat is hard to escape is bonded to a circuit terminal whose heat capacity is large because the surface area is large. Thereby the heat capacity of each junction part is made equal. On the contrary, it is also possible that the area of a circuit terminal 3 is set according to the width of an outer lead and the heat capacity of each junction is made equal.

Title: Electrolytic method
Inventor: YAMAGUCHI HISAO
IPC: C25F3/16
Filed: 1999-06-10
Abstract: PROBLEM TO BE SOLVED: To uniformly perform electrolytic etching for the whole surface of a face to be electrolytic-etched by varying an electric current flowing between a work and an electrode with the passage of the time. SOLUTION: A cylinder bore is subjected to honing (honing is not electrochemical processing), and subsequently the honed cylinder bore surface is subjected to electrochemical processing in which an electric current flowing between an electrode 1 inserted in the cylinder bore and the cylinder bore surface varies with the passage of time to roughen the cylinder bore surface (more rough than the honing machined surface) to form a surface having favorable oil retaining performance. At this time, first, a smaller current is carried, whereby a region where a current is easily to concentrate is first subjected to electrolytic etching so that the region where a current is easy to concentrate is eliminated. Thus, the whole surface of a fact to be electrolytic-etching can be uniformly electrolytic-etched.

CONSTITUTION: A pendulum unit 14 is composed of a rectangular pendulum 8, a frame 12 fixed to a substrate 10, and a hinge 16 which connects the pendulum 8 to the frame 12 in a rotatably state and the pendulum 8, frame 12, and hinge 16 are integrally formed by machining one piece of conductive material. The pendulum 8 has a flat conductive surface, namely, an electrode 22 on one surface and the electrode 22 is faced to electrodes 18 and 20 provided on the substrates 10 at intervals of about several μm. A calibrated voltage pulse having a prescribed amplitude and duration is supplied to one of the electrodes 18 and 20 so as to make the capacitances of capacitors respectively formed of the electrodes 18 and 22 and 20 and 22 equal to each other.  Since the magnitude of the electrostatic force which restores the pendulum 9 turned by an acceleration force is proportional to the frequency of the voltage pulse and the acceleration force is proportional to the magnitude of acceleration, the magnitude of the acceleration can be indicated by the frequency of the voltage pulse.

Filed: 1999-06-11
Abstract: PROBLEM TO BE SOLVED: To provide a high speed operation by intervening a source follower type logic circuit between an input logic circuit which outputs a logical signal with an upper limit value as a potential higher than a power source potential and a lower limit value as a potential higher than a ground potential and an output driver which outputs a logical signal with an upper limit value as the power source potential and a lower limit value as the ground potential. SOLUTION: Since a source follower type logic circuit 18 is intervened between a pseudo-nMOS circuit 11 and a CMOS inverter 22, it is possible to shift a center potential of an output logical signal of the pseudo-nMOS circuit 11 in a ground potential direction even if a lower limit value of the output signal of the pseudo-nMOS circuit 11 is raised and an amplitude of the output logical signal of the pseudo-nMOS circuit 11 is made smaller. Therefore, even if a circuit threshold of a CMOS inverter 22 is lower than the central potential of the output logical signal of the pseudo-nMOS circuit 11, it is possible to have the CMOS inverter 22 operate so that a rising time and a lowering time becomes equal to each other.

Inventor: MIZUTANI SHIN
IPC: G06F15/18
Filed: 1998-06-12
Abstract: PROBLEM TO BE SOLVED: To detect a feeble time space pattern hidden in noise by frequency- analyzing the time sequence of a multidimensional variable showing the state of a neural network and the distance from the space pattern and checking the peak of frequency distribution. SOLUTION: A plurality of time space patterns which do not contain noise and which are desired to be detected, are made to be spatially discrete and are quantized to be binary (101). A neural network is cooperatively learnt by using the binarized space pattern (102) and multidimensional time sequence where the time space pattern containing noise in time and space is made to be spatially discreted is inputted to the neural network (103). The time periodicity of the time space pattern which is made spatially discrete is amplified by using a possibility resonance phenomenon (104) and the time sequence of the multidimensional variable showing the state of the neural network and the distance from the learnt space pattern is calculated (105).  The time space pattern having time periodicity is detected by analyzing the frequency of time sequence obtained by calculation and checking the peak of frequency distribution (106 and 107).

Title: Analog/digital converter
Inventor: HAYASHI YOSHINORI
IPC: H03M1/40
Filed: 1990-06-22
Abstract: PURPOSE:To attain a high bit processing with simple constitution by changing a digital output data always while following to an analog input signal. CONSTITUTION:The output data of an adder 6 is converted into an analog signal by a D/A converter 8 and fed to a differential amplifier 4 as a tracing signal Vs. Then a signal in response to a difference between the tracing signal Vs and an analog input signal Vin is outputted to the differential amplifier 4, in which the signals are converted into 3-bit difference a data and added in an adder 6 sequentially. When the tracing signal Vs is coincident with the analog input signal Vin and the difference data is zero, the output data of the adder 6 is constant. Thus, the output data from the adder 6 is changed always in following to the analog input signal Vin and the output data is outputted as a digital output data via a latch circuit 7.
