Abstract: PURPOSE:To provide a highly efficient inter-cooler for cooling supercharged air, which is independent from the operating condition of an engine and which may utilize an existing refrigerating cycle, by utilizing coolant in the refrigerating cycle as a cooling source for the inter-cooler. CONSTITUTION:Air is fed to an engine body 1 from a pipe 27 through a blower 22, a pipe 26, an inter-cooler 21' and a pipe 25 in a turbo-charger, and exhaust gas is discharged through an exhaust pipe 28, a turbines 23 and a pipe 29 n the turbo charger and a pipe line 29. A compressor 31 for a cooler system 30 such as, for example, car-cooler, etc., driven by an engine 11 compresses coolant, and the thus compressed coolant cools the passenger's compartment, passing through a condenser 32, an expansion valve 33, a valve 35 and an evaporator 34, and then returns to the compressor through a valve 37. Upon operation of the inter-cooler 21' a valve 36 is opened to introduce a part of coolant into the inter-cooler. The coolant is then returned into the compressor 32 through a valve 38 after air being cooled.

Filed: 1997-09-11
Abstract: PROBLEM TO BE SOLVED: To reduce quantization noise that is caused by a frequency and to improve performance by quantizing a result which adds data that is undergone size adjustment to filtered data. SOLUTION: This converter performs a filtering operation of difference data between two adjacent oversampled data through a low pass filter or a high pass filter and a different size adjustment operation and quantizes a result of adding data that is size-adjusted to filtered data. That is, the converter filters inputted difference data and generates data which is band-limited. The data which is band-limited is inputted to an adder 35. The adder 35 adds data which is supplied from an integrator 33 to the data which is supplied from a filter 34 and band-limited, and outputs the result to a quantizing part 36. The part 36 quantizes the data supplied from the adder 35 into one bit data.

Inventor: OI YASUSHI
IPC: G06F9/38
Filed: 1990-09-18
Abstract: PURPOSE:To attain the most effective application of the delay branch by using the conditional delay branch for formation of a loop and using no delay branch for division of a case. CONSTITUTION:An access is applied to the contents of an instruction memory 113 based on the value of a fetching instruction counter 101, and an instruction word is inputted to a latch 123. A branch condition deciding circuit 132 decides whether the conditions designated by a conditional branch instruction are satis fied or not based on an instruction decoder 135 and a status register 161. A branch execution deciding circuit 131 produces a branch execution deciding signal and a delay instruction execution deciding signal. The latter signal is latched by an instruction invalidation flag latch 121. Thus, it can be decided whether the instruction following a branch instruction should be carried out or not based on the contents of the latch 121 when said instruction is decoded. In such a way, the conditional delay branch is used for formation of a loop and no delay branch is used for division of a case, respectively. Thus, the most effective application is assured for the delay branch.

Title: Defuzzifier circuit for fuzzy computer
Inventor: NAKAO JUNJI
IPC: H03K19/173
Filed: 1988-09-30
Abstract: PURPOSE:To output an accurate deterministic value by performing correct evaluation without ignoring the voltage output at the time of centroid operation even in case that a prescribed voltage V0 is obtained from an endmost line L0 out of output lines of a fuzzy operation part. CONSTITUTION:Outputs are given fro plural lines L0 to Lm by outputs of a fuzzy operation part 1. These outputs are connected to (m+1) number of first resistance groups 2 having resistance values R/(N+1+n)(n=0 to (m)) and (m+1) number of second resistance groups having the same resistance value (r). The other ends of first and second resistance groups 2 and 3 are connected in common and are connected to a divider 8. The divider 8 divides inputs connected in common of first resistance groups 2 by inputs connected in common of second resistance groups 3 to perform centroid operation. A bias subtractor 9 is used to correct the center value by the output of the divider obtained in this manner, thus obtaining the deterministic value as a non-fuzzy output.

Title: Arithmetic circuit
Inventor: KATSUNO AKIRA
IPC: G06F7/00
Filed: 1988-09-30
Abstract: PURPOSE:To realize the working of an arithmetic circuit at high speed at the time of 0-shift with no deterioration of shift processing speed by outputting the external input data directly to the outside via an added bypass means when a selection circuit of the final stage receives an 0-shift instruction. CONSTITUTION:A bypass line 42 having the 10-bit width is connected to the input side of a selection circuit 41d of the final stage to supply the data inputs I0 - I9 directly to the circuit 41d. The circuit 41d uses a 3-input/1-output type and receives the input of a selection signal S0 (0-shift instruction) in particular in addition to a shift signal S1. Then the inputs I0 - I9 transferred via the line 42 are outputted directly to the outside regardless of the level of the signal S1 when the selection signal is active (S0 = 1). Therefore the delay time caused at 0-shift is equal to only a through amount of the circuit 41d and the processing speed is extremely increased. Furthermore, no selection circuit except a shifter is required and therefore the entire constitution of an arithmetic circuit is simpli fied.

Abstract: PURPOSE:To provide a comfortable air-cushion boat, by providing a stern seal controller mechanism so as to retain an appropriate pressure in an air-cushion room. CONSTITUTION:A part of compressed air to flow from a floating fan 5 to a bag-form stern seal 3 through a duct 7 can be exhausted from a louver 9 for control of stern seal to the outside of the boat through an extended duct 8, when the pressure in the air-cushion room 4 rises up due to the heave of wave level. When the inner pressure of stern seal 3 drops in this way, a clearance appears between the lower face of the stern seal 3 and the sea level 13 and air leaks from the air-cushion room 4. And hence, the air pressure in the air- cushion room 4 is returned to its appropriate value. When the pressure in the air-cushion room 4 drops due to the decrease of wave level, the louver 9 is closed and the clearance is shutt. In this way, the air pressure in the air-cushion room 4 is increased and returned to its appropriate value.
