Abstract: PURPOSE:To improve the knock detecting accuracy, by furnishing plural knock discriminators, and arranging an exclusive power circuit combined to each of the discriminators, in the system with the knock discriminator to detect selectively the generation of knocking from the output of knock sensors. CONSTITUTION:Knock discriminators 40 and 50 are provided to input the output signals of acceleration sensors 41 and 51 which are installed at an engine and detect the vibrating acceleration of the engine. The knock discriminators 40 and 50 are composed of frequency filters 42 and 52, analog gates 43 and 53, noise level detectors 45 and 55, and comparators 46 and 56 respectively, and a constant voltage is fed through power supply circuit 47 and 57 connected to a battery 60 respectively. Since the detected output of the acceleration sensors 41 and 51 are of different amplitudes and phases each other, and the operating wave forms of parts of the discriminators 40 and 50 are also different, the variation of consuming currents is liable to give influence each other. However, the power supply circuits 47 and 57 installed respectively to each discriminator 40 and 50 prevent such an influence.

Abstract: PURPOSE:To prevent light emitting seepage in the periphery of a p type region and leakage light emitting from an adjacent p type region by specifying the thickness of an n type GaAs substrate and a doping concentration of Zn to form the p type region thereon. CONSTITUTION:A diffusion mask 2 comprising nitride silicon, oxide silicon and the like is provided on an n type GaAs substrate 1. As this diffusion mask 2 diffuses Zn at a thickness of 10 to 5Omum in the same pitch over the substrate 1, a p type legion 3 having a p type conductivity is formed to form a semiconductor light emitting device. Note that the thickness of the n type GaAs substrate 1 shall be over 25mum. When the peak intensity of the emission spectrum is I0, the Zn doping concentration to the p type region 3 is so determined that the longest wavelength end lambdam of an 10/2 portion will be under 910nm. Thus, light emitted in the p type region is absorbed before reaching the lower surface of the n type GaAs substrate and the absorption coefficient of the n type GaAs substrate to the emission spectrum becomes high.

Filed: 1995-07-19
Abstract: PROBLEM TO BE SOLVED: To make the force of a wind and an impact at the time of contacting an object absorbed and to improve durability by making an umbrella vertically movable and rotatable. SOLUTION: In the case of contacting the umbrella of another person in a narrow place, the considerable impact is received by a hand, excessive force is applied to the umbrella as well and it becomes the cause of damage. Also, when the wind is received at one part, the force is applied to only one part and it becomes the cause of the damage. Thus, by vertically moving the umbrella and rotating it to left and right, impact force is absorbed and the damage is prevented. Therefore, a shank, a handle and a ring are divided or turned to a movable type and made to move up and down and to left and right. That is, the shank is divided into the shank 1 and the shank 2 and connected by a screw 3 and a nut 4 or it is manufactured by putting the shank 1 to which a projection is attached to a ring 5.  Further, the shank 1 is provided with the projection, the ring 5 and a spring 7 are put in, an adjustment screw 10 and a stopper 8 are formed and thus, vertical movement and rotation speeds are adjusted and the movement of the umbrella is made controllable.

Filed: 1981-12-28
Abstract: PURPOSE:To prevent transfer failure even in case of transfer paper to which a small quantity of paper powder has adhered, by using a destaticizing device in the vicinity of a transfer part. CONSTITUTION:A printing form 1 which has adhered paper powder onto the surface is fed in the direction as indicated with an arrow by upper and lower paper feed tractors 12. A destaticizing device 13 is installed so as to be opposed to the whole width direction of a loaded printing form. When the printing form 1 is opposed to the destaticizing device 13, static electricity of the paper surface is eliminated, and as a result, electric attracting force between the paper powder and the surface of the printing form is eliminated, and the paper powder is separated from the surface of the printing form 1. The printing form 1 contacts only with a cover 14 as a result of running, therefore, the paper powder which has lost attractive force to the surface of the printing form passes under the cover 14 by vibration of the form in the course of running, and drops in the opposite direction to the running direction of the form.
