Filed: 1999-06-14
Abstract: PROBLEM TO BE SOLVED: To prevent a fracture along an extruding direction and to improve yield by recessing a plurality of lateral flutes perpendicularly to the extruding direction by hot pressing. SOLUTION: A resin foamed material A is drawn from a containing roller 1, preheated by a preheater 2, and then sent to lateral flute forming rollers 3. When an apparatus is operated, blades 3b of the rollers 3 are rotated while biting the material A, and the material A is processed, and conveyed to a rear stage. Heating temperatures of the blades 3b are different according to a melting temperature of the material A. For example, in the case of a polypropylene resin, a melting point of the polypropyene is 164 to 170 deg.C, and the heating temperature of the blades 3b is set to a range of 150 to 200 deg.C in response to a pressurizing force of the blades 3b. Then, after a 'sag' is provided so that the processing complete sheet may not be torn, the sheet is recovered to a winding roller 5. Here, conveying speeds of the rollers 3 and 5 are regulated substantially the same.  Thus, a fracture along the extruding direction can be prevented, and its yield can be improved.

IPC: G02F1/09
Filed: 1994-07-19
Abstract: PURPOSE:To obtain an isolator which is small in size, is large in effective diameter and is decreased in the variations in the angle of a polarizer and a Faraday rotor by clamping this Faraday rotor by two pieces of magnets magnetized in the same direction. CONSTITUTION:Two pieces of the magnets 15 of the optical isolator formed by juxtaposing the polarizer 13, the magnet 15, the Faraday rotor 16, the magnet 15 and an analyzer 14 are magnetized in parallel with the optical axis and in the same direction. Sufficient accuracy is obtainable in working of the parallelism, perpendicularity, etc., of the respective members and, therefore, the angles formed by the polarizer 14, the analyzer 14 and the Faraday rotor 16, are fixed at the angle formed by the outside diameter and inside diameter of an outside frame 11 of the optical isolator. For example, the polarizer, etc., are perpendicularly fixed if the outside diameter and the inside diameter are parallel. The polarizer, etc., are fixed with an inclination 4 deg. from the perpendicular if the outside diameter and the inside diameter incline 4 deg.. Then, there is no need for using the holder to be exclusively used for fixing the Faraday rotor and, therefore, the variations in the angles are suppressed within + or -1 deg. without reducing the effective diameter.

Title: Control device for internal combustion engine
Inventor: SHIBAGAKI NOBUYUKI
IPC: F02D41/04
Filed: 1998-06-15
Abstract: PROBLEM TO BE SOLVED: To prevent the output torque of an internal combustion engine from varying so as to prevent deterioration of drivability during the type of combustion such as rich spike control is stepwise changed. SOLUTION: During rich spike control, when the type of combustion in an engine 11 is changed over from weak stratified charge combustion from a homogenous lean combustion, the openings of a throttle valve 23 and an EGR valve 43 are changed into the closed position side suitable for the homogenous lean combustion after the above-mentioned change-over. Further, in order to prevent the output torque of the engine 11 from being changed due to a change in the throttle valve opening into the closed position side, the fuel injection rate is compensated so as to be increased during the change-over of the abovementioned type of combustion. Further, when the opening of the EGR valve is changed into the closed position side, a responsive delay occurs in decrease of the EGR rate caused by the change of the opening thereof.  Further, during performance of the homogenous lean combustion after the change-over, the fuel injection rate is compensated so as to be increased in order to prevent the output torque from lowering due to the responsive delay in decrease of the EGR rate.

Patent JP-S6146628-A (JP)
Title: Line switching device
Inventor: KURATA MASAAKI
IPC: H04B1/74
Filed: 1984-08-13
Abstract: PURPOSE:To prevent inexpensively and simply malfunction caused at the leading of a power voltage by inserting a Zener diode to a signal line from an output stage of a control circuit to a latching type line switch drive circuit. CONSTITUTION:A spike noie voltage SP is generated by application of a power voltage when the power voltage VCC rises by DELTAV. Since the DELTAV is generally nearly 2V, no trigger pulse TP is produced by making an output stage of a control circuit 12-1 and an input stage of a switch drive circuit 13-1 nonconductive only just after the VCC exceeds the DELTAV. Thus, since the Zener diode 21 remains cut off until the voltage VCC exceeds the DELTAV by setting a Zener voltage of a Zener diode 21 to a VCC/2, no pulse TP is generated and after the voltage VCC rises out into 5V, a line switching signal is produced.

Filed: 1989-06-28
Abstract: PURPOSE:To ensure the color reproducibility and to avoid a hue change in the transient portion by improving the transient phenomenon through the passing of an original signal through an amplifier and a delay line only without modulation or demodulation. CONSTITUTION:A color signal 12 inputted with original signal input is inputted to demodulators 4, 5, to which a carrier with a 90 deg. phase difference is fed via a phase shifter 11 from a carrier synchronized with a burst signal of a color signal simultaneously. Then color difference signals 13, 14 outputted from the demodulators are given to a linear differentiating extraction devices 6, 7, from which linear differentiating components 15, 16 are extracted, the result is subjected to absolute value processing by absolute value circuits 8, 9 and the result is inputted to an adder 10 and its output 19 controls the gain of an amplifier 2. Moreover, a delay line 1 compensates a time to form a control signal. The extraction system for the transient part passes through the demodulation process, but the main signal does not pass through the demodulation process but passes only through an amplifier. Then the deterioration in the color reproducibility and the hue change in the transient part due to the improvement of the transient phenomenon are avoided.
