Title: Heat exchanger
Inventor: SASAKI HIRONAKA
IPC: F28D1/053
Filed: 1986-10-30
Abstract: PURPOSE:To provide a heat exchanger which can reduce its manufacturing cost and is equipped with fins having low thermal resistance by shaving and raising the outer surface of tube at a regular interval so that a number of raised fins may be formed between the adjacent tubes. CONSTITUTION:By shaving and raising the top and underside of multiple flat tubes 3 connected to hollow headers 1, 2 at regular intervals in the lengthwise direction of the tubes 3, a number of raised fins 4 are formed. The headers 1, 2 have tube inserting holes 5 and partitions 10 at predetermined intervals. The refrigerant flowing from a refrigerant inlet tube 6 to the header 1 passes back and forth between the headers 1, 2 and is discharged from a refrigerant outlet tube 7. In this manner, the fins 4 and tubes 3 can be made of a common single component, allowing a reduction of manufacturing cost and an improvement of thermal efficiency.

Title: Noise elimination circuit for amplitude modulation signal and noise elimination circuit for voice signal
Inventor: KONDOU YOSHINOBU
IPC: H03H17/00
Filed: 1996-09-30
Abstract: PROBLEM TO BE SOLVED: To provide a nonlinear filter with a frequency characteristic. SOLUTION: An input signal being an AM signal of a specific frequency with impulse noise superimposed thereon is given to an input terminal of a sample-and-hold circuit 11. A clock signal CLK with a frequency of 2fc is fed to a control terminal of the sample-and-hold circuit 11. The sample-and-hold circuit 11 holds the input signal (in) at a leading timing of the clock signal CLK and provides an output to an A/D converter 12. The A/D converter 12 converts the input signal (in) into a digital signal of a fixed decimal point form and provides an output of the converted signal to a shift register 21. The shift register 21 latches and shifts a signal stream rn and provides an output of the result to a nonlinear arithmetic circuit 22.  The nonlinear arithmetic circuit 22 receives '0s' and signal streams and applies nonlinear filter processing to them and provides an output of the result to a D/A converter 31. The D/A converter 31 converts the digital signal of the fixed decimal point form into an analog signal.

Title: Searching method of hole in automatic measurement by robot for three-dimensional measurement according to teaching playback system
Inventor: YAKUYAMA TAKASHI
IPC: B25J13/00
Filed: 1987-10-16
Abstract: PURPOSE:To make it possible to find out a hole position without any hindrance even when a hole position according to teaching data is different from the actual hole position within the allowable limits, by providing a plurality of search points set on concentric circles around a measurement starting point. CONSTITUTION:A probe 3 is moved to measurement starting points P and P' and made to approach by a distance L. When the starting point is located in a hole 21 as the point P', in this case, the probe 3 gets in the hole 21 and does not generate an ON signal. When the starting point is outside the hole 21 as the point P, on the other hand, the probe touches the surface of a substance 20 to be measured and generates the ON signal according to this constitution. Accordingly, the position of the hole 21 can be discriminated on the basis of the presence or absence of generation of the ON signal. When the ON signal is present, the probe 3 is made to approach sequentially a plurality of search points S1-S24 set on concentric circles around the measurement starting point P, beginning with ones located on the circle having a smaller radius R1, and when the probe 3 generates an OFF signal in the course of this approach, the search point whereat the OFF signal is generated is decided to be a true measurement starting point. Accordingly, automatic measurement of the hole can be executed even when there is a difference in position between a measurement starting point of the probe according to teaching data and the actual hole position.

Abstract: PURPOSE:To effectively prevent outflow of oil loaded in a tank by locating an inner wall, having expandable flexibility, on the inner side of the topside plating of a tanker to form a broadside double shell structure, and intercommunicating a low pressure tank and a tank when breakage occurs in a ship bottom. CONSTITUTION:When a topside plating 4 is broken owing to collision with other ship, since an inner wall 5 being a bellows type partition wall having expandable flexibility is located on the inner side of the topside plating 4, the inner wall 5 is only locally expanded and not broken even when the bow part of other ship breaks through the topside plating 4. When a tank bottom part 3 is broken owing to running aground and the change in a pressure of a gas part 17 in the tank is sensed by a pressure detector 19, an inert gas system valve 15 and a safety valve 16 are closed, a low pressure system control valve 8 is opened, and a low pressure tank 6 is coupled. This constitution pushes up loaded oil 18 through reduction of a pressure in a broken tank, and prevents outflow of the loaded oil 18 in a way that a valve 8 is closed in a state that a liquid level is raised to a proper position.

Abstract: PURPOSE:To obtain an interesting mechanism especially as a toy or a simple sound reproducing machine by replacing a record disk only by inserting the record disk into a record disk insertion slit formed on a casing itself and pressing an ejector lever. CONSTITUTION:At the insertion of a record disk 20 from the record disk insertion slit 8, the record disk 20 lifts a stylus pressure releasing projection 19 by using the circular actuate tip part of the projection 19 and the projection 19 lifts a sound transmitting member 13 to release the stylus pressure of a pickup P.

Since the record disk 20 is removed from the position of the projection 19 when the record disk 20 is inserted into the slit 8 until a centering projection 30 is engaged with a centering hole 21, stylus pressure is applied to the pickup P. When a turntable 6 is totated, a record disk hooking projection 6b is engaged with a notch 22 and the record disk 20 is rotated integrally with the turntable 6.
