Title: Cylinder head for internal combustion engine
Inventor: YOSHIMURA TOORU
IPC: F02F1/42
Filed: 1980-03-10
Abstract: PURPOSE:To improve an output fall due to the exhaust interference while maintaining proper function of a Siamese type exhaust passage, by providing a port liner which is located on a heat-insulating layer on the inside of an exhaust port and has independent parts for cylinders. CONSTITUTION:A port liner 14 is divided into two portions from a gathering part 14c on two branched parts 14a, 14b. Thin members 15a, 15b are welded on the edge of the dividing part 14c and coupled with each other by spot welding or the like. A partition wall 15 consisting of both the thin members 15a, 15b hinders confluence of the exhaust gas in the port liner 14. Namely, the partition wall 15 interrupts confluence of the exhaust gas in the exhaust port gathering part 14c to reduce the exhaust interference in terms of time and distance. The partition wall 15 is made so thin that escape of exhaust heat due to conduction through the wall is suppressed as much as possible. As a result, the proper function of a Siamese type exhaust port is almost maintained.

IPC: F16B47/00
Filed: 1996-02-16
Abstract: PROBLEM TO BE SOLVED: To provide a suction panel having sufficient sucking force and easily moved or demounted. SOLUTION: A suction panel main body 21 and a pulling hand part 24 are formed in a single body with elastic material and those components are jointed to each other by means of a suction releasing wire 27. When a suction panel 20 is moved, firstly the pulling hand part 24 is grasped in a hand and pulled slantly downward lightly. Then, since a connection plate 23 inclines and the suction releasing wire 27 peels off one part of the suction panel main body 21 from its mounting surface, air invades in through a generated gap so as to release the sucked state. Hereat, when a sun visor is moved to a desired position and the pulling hand part 24 is pressed on a mounting surface, a wire connection part 25 and a pressing part 26 provided in the pulling hand part 24 push a light shield plate 11 in good balance, resultantly the suction panel 20 is fixed certainly and quickly.

Title: Semiconductor-laser driving apparatus
Inventor: IKEUCHI AKIRA
IPC: H04B10/293
Filed: 1994-02-28
Abstract: PURPOSE:To simplify the adjustment of a bias current, to eliminate the adjustment or to reduce the bias current by a method wherein a reference voltage for a semiconductor-laser driving apparatus which emits light when a current at a threshold value or higher flows is provided with a temperature characteristic. CONSTITUTION:On the basis of the characteristic of a semiconductor laser 11, the variable resistance of a driving-current control part 14 and that of a bias-current control part 15 are adjusted at a low temperature so that desired optical output power is obtained and that a bias current becomes equal to a threshold current value. When a temperature is raised in this state, the threshold current of the semiconductor laser 11 becomes large, and its delay time becomes large. However, since the level of a reference voltage is lowered according to a temperature rise, the duty of a driving current is increased, and the time in which the driving current starts to flow to the semiconductor laser 11 is hastened. When the rise of the driving current is hastened, the delay time can be offset, and a stable optical output waveform can be obtained.

Filed: 1993-02-19
Abstract: PURPOSE:To reduce mechanical noise and cylinder noise by providing an omnidirectional electret condenser microphone, a wall at the back side of the microphone and an equalizer circuit attenuating a high frequency characteristic of an output of a high pass filter to the camcorder. CONSTITUTION:An audio signal inputted to an ECM 1 is given to an HPF 22, in which its low frequency is attenuated. In the case of a sound emitted in four directions from a sound source, its high frequency characteristic is increased by a diffraction effect of a sound wave because of the provision of a wall 3 around the ECM 1 and the frequency characteristic at that time is a characteristic shown in a frequency characteristic 26 with a parameter of a sound source A at the output of an HPF 22. Furthermore, in the case of a sound emitted in five directions from a sound source, the frequency characteristic is a flat frequency characteristic as shown in a frequency characteristic 26 at a parameter of a sound source B at the output of the HPF 22 because no wall is provided. Moreover, in the case of a sound emitted in six directions from a sound source, the frequency characteristic is a frequency characteristic whose high frequency is decreased as shown in a frequency characteristic 26 at a parameter of a sound source C at the output of the HPF 22 because a VTR 2 acts like a wall and the high frequency is interrupted. A frequency characteristic of a sound emitted in four directions from a sound source is a frequency characteristic 27 at an output of an equalizer by adding the equalizer 23 to attenuate the high frequency.

Title: Voltage controlled piezoelectric oscillator
Inventor: KANAZAWA NOBUYUKI
IPC: H03B5/32
Filed: 1988-02-10
Abstract: PURPOSE:To improve the temperature characteristic by compensating a cancellation difference between a temperature characteristic of a crystal vibrator and a temperature characteristic of the circuit except the crystal resonator through the connection of a diode whose forward voltage varies with temperature to a voltage variable capacitive element. CONSTITUTION:A resonance point of a crystal resonator 7 is reduced from the series resonance point by a variable inductor 8, the inductance is selected as, e.g., 60muH to increase the frequency variable range by the capacitance of the varactor diode 10. Then the gradation of the circuit temperature characteristic is made steep and the forward voltage is reduced attended with temperature rise by taking the temperature characteristic of the diode 12 into account. Then the applied voltage to the varactor diode 10 is changed, the capacitance is increased at a low temperature and decreased by high temperature. Then the oscillated frequency is lowered at low temperature and increased at high temperature, resulting in relaxing the slope of the temperature characteristic of the circuit side. Thus, the characteristic is cancelled with the temperature characteristic of the crystal vibrator causing the linearity increasing to the right, then the frequency change due to temperature is reduced.

Abstract: PURPOSE:To obtain a baggy separator free of declamination in its bonded portion by the procedure in which a thermoplastic resin film is made into a baggy form by hot adhesion and then a modification reaction, e.g., introduction of sulfone groups, etc., is made on the resin. CONSTITUTION:The thermoplastic resin films 1 and 2 of ethylene or propylene- acrylic monomer, methacrylic monomer, or vinyl acetate copolymer, etc., are made  into a baggy form by thermally adhering sides 3-5, and then subjected to a modification reaction, e.g., introduction of sulfone groups, etc. For example, the thermoplastic resin films 1 and 2 of ethylene-methacrylic acid copolymer, having a methacrylic acid copolymerization ratio of 15mol% and a thickness of 40 microns,  are superposed and hot-melted at the three sides 3-5 in a 1mm width to form a  bag. Then, the bag is dipped in a fuming sulfuric acid containing 5% free SO3 for  30 seconds in order to introduce sulfone groups into the resin. Thus, a baggy separator which is excellent in acid resistance and alkali resistance can be obtained,  consisting of the resin film which is incapable of being melted by heating or hard to melt for adhesion after its modification.
