Title: Filter circuit
Inventor: MARUYAMA RYOJI
IPC: H03H11/04
Filed: 1989-08-04
Abstract: PURPOSE:To set a harmonic components ratio to an input signal optionally by revising a transfer function in response to the frequency of an input signal. CONSTITUTION:A comparator 1 detects passing of zero volt (zero cross) of an input terminal from an input terminal 3. Moreover, a counter 5 receives the result of detection of the comparator 1 and counts the number of pulses with a prescribed frequency supplied from an oscillator 7 from the rise of the pulse till the rise of the succeeding pulse. That is, since the rise interval of the pulses corresponds to the frequency of the input signal through the zero cross detection by the comparator 1, the frequency of the input signal is detected as the number of pulse with a sufficiently high frequency. Then a coder 9 outputs a 4-bit control signal for on/off of switches SW1-SW8 in response to the result of the detection of the frequency of the input signal from the counter 5. Thus, the transfer function is changed in response to the frequency of the input signal to adjust the parameter such as a cut-off frequency is optionally adjusted.

CONSTITUTION:An input image characteristic extraction device 1 receives the two-dimensional image of an objective three-dimensional body from one camera to extract at least three of more characteristic segments and two or more characteristic points. An image-body correspondence checking apparatus 3 checks for correspondence between characteristics of characteristic segments and characteristic points and the characteristic description in the body model segment and body model point descriptions from a body model description memory device 2 and selects two points and three segments from matched ones to form the image/body correspondence table thereof. In a two-point three-segment posture estimation apparatus 4, candidates of three-dimensional arrangement are independently calculated with respect to three kinds of standard three segments composed of segments prescribed by two segments among three segments and two points and the matching therebetween is calculated next to estimate a posture of two points and three segments at least. By this method, the posture of a body being an object can be estimated.

IPC: F02B29/06
Filed: 1987-08-13
Abstract: PURPOSE:To provide excellent combustion through simple constitution, by a method wherein an air forced feed pore having an opening are smaller than that of a suction hole is formed in the inner peripheral surface of a cylinder, and pressurized air is forcibly fed in the cylinder through the pore right before a piston is shifted to a compression stroke. CONSTITUTION:An air forced feed pore 4 having an opening area smaller than that of a suction hole 1 is formed in the inner peripheral surface of a cylinder 3 having the suction hole 1 and an exhaust hole. When a piston 5 is lowered within a cylinder 3, air-fuel mixture is sucked through the suction hole 1, and when a piston 5 is lowered to a bottom dead center, and the suction hole 1 is closed to compress the air-fuel mixture. In this case, right before the piston 5 is shifted to a compression stroke, pressurized air is forcibly fed in the cylinder 3 in a closed state through the air forced feed pore 4. Thus, the cylinder 3 can be filled with the air-fuel mixture in an amount suitable for completion combustion. This constitution enables achievement of complete combustion of the air-fuel mixture through simple structure.

Title: Switch operation device
Inventor: FUJIMURA SHIGERU
IPC: H01H33/38
Filed: 1998-07-17
Abstract: PROBLEM TO BE SOLVED: To approximately maximize the transmission force of an operation coil when an applied load is maximum, and shorten the operation stroke of a moving core for making the operation coil compact. SOLUTION: During the first stage of the travel of the moving rod pin 24 of a moving core 21, the moving pin 24 presses the peripheral end of a second lever slot 11 and causes a moving contact 10 to come in contact with one of stationary contacts 6. During the subsequent second stage of the travel of the moving rod pin 24, a connecting link 17 travels, due to an auxiliary pin 15. As a result, the peripheral end of a connecting slot 18 presses the third lever pin 12. An angle formed by a line drawn between the auxiliary pin 15 and an auxiliary shaft, 14, and a line drawn between the auxiliary pin 15 and the third lever pin 12, is thereby made approximately equal to 180 degrees, and the moving contact 10 is kept in forced contact with the other stationary contact 6.  Furthermore, the moving rod pin 24 during the third stage of a travel again presses the peripheral end of the second lever slot 11 and keeps the moving contact 10 in sidable contact with the other stationary contact 6. An angle formed by a line drawn between the auxiliary pin 15 and the auxiliary shaft 14, and a line between the auxiliary pin 15 and the third lever pin 12 is thereby made somewhat larger than 180 degrees.
