Title: Combustion device
Inventor: NAKAO YOSHIHIRO
IPC: F23D3/10
Filed: 1987-06-12
Abstract: PURPOSE:To prevent a noise or flame flare during maximum combustion or when a wind is blown in and to obtain a safe and favorable combustion device which has a good combustion characteristic and a wide range of adjustment for a combustion amount, by providing a wind shut-off plate between a flow controlling cylinder and an inner flame cylinder in a portion opposed to a vent hole of the flow controlling cylinder. CONSTITUTION:Between a flow controlling cylinder 21 and an inner flame cylinder 6 opposed to a vent hole 28 of the flow controlling cylinder 21 is provided a wind shut-off plate 34 whose top end is secured to a shielding portion 29 and whose lower end is continuous to an opening 34a. Since air entered through the vent hole 28 flows downward, after impinging against the wind shut-off plate 34, and is discharged through the opening so as to be supplied toward an air port 33, the holding of a stable flame at the portion thereof is not interfered by the air current and no combustion noise is generated. Further, the air entered through the vent hole 28 is streamed into a lower flow control area 30 in a clean current form, and consequently the mixture with unburnt gas can be efficiently carried out. Even when the exposed height of a wick 1 is lowered, combustion is quickly accelerated in the same state as mentioned above without generating combustion noise, nor even causing the flicker of a flame, etc., and accordingly the clear combustion generating less CO or malodor may be realized.

Title: Image recording device
Inventor: ISHIDA TSUTOMU
IPC: G03G5/00
Filed: 1981-09-18
Abstract: PURPOSE:To record a negative-positive image, a positive-positive image, and a synthetic  image, by recording a negative image by the writing due to a red laser light and recording a positive image by the projection of an original optical image through a red filter. CONSTITUTION:In the positive-positve image recording mode, when a photoreceptor 1 is charged with the negative polarity in the dark, an electric double layer is formed through a photoconductive layer 13 because there is the rectifiability for the positive electric charge between a conductive substrate 10 and a photoconductive layer 11. When the photoreceptor is charged secondarily in the dark to neutralize the negative electric charge partially, the state where layers 11 and 13 are charged in directions  opposite to each other is realized. Next, when the optical image of an original O is projected onto the photoreceptor 1 through a red filter F1, a reflected light LW from a white ground W of the original O becomes a red light LR, and a part of the photoreceptor corresponding to a nonimaged part is irradiated with this light. The charging state of the layer 11 on the photoreceptor 1 is dissolved, and the surface potential is inverted to the negative polarity again, and the positive-polarity photoreceptor surface potential distribution corresponds to an image part N of the original O. Consequently, the image is developed with a negative-polarity toner to obtain a visible image. Thereafter, the image is transferred and fixed.

Further, since the swash plates 10 and 20 are provided with the center adjusting action, the load of the swash plate holders 5a and 22 for supporting the swash plates 10 and 20 can be reduced, and durability can be improved.

Abstract: PURPOSE:To apply the normal bias to a magnetic head by delivering the comparison output between the effective bias amount to be supplied to a recording head and a reference voltage level via a limiter and controlling the gain of a voltage control oscillator whose output is superposed on the recording signal after receiving supply of the oscillator output. CONSTITUTION:The terminal voltage of a recording head 1 is applied to a peak wave detector via an LPF4 consisting of a resistance 2 and a capacitor 3. The detection output of the detector 5 is compared with the voltage level of a reference voltage source 9 by a comparator 6. The output of the comparator 6 is applied to a gain control input 11 of a voltage control amplifier 10 via a limiter 17. A part of the oscillation output of an erasion oscillator 12 is applied to the input of the amplifier 10. The output of the amplifier 10 is superposed on the signal voltage applied from a signal input terminal 13 by an adder 14 and applied to the head 1. Thus it is avoided that a no-bias state is caused when a large high band component included in a signal to be recorded is eliminated. Then the normal bias can be applied to a magnetic head.

Title: Center height measuring device for cutting tool
Inventor: TAKASHITA JIRO
IPC: G01B5/02
Filed: 1985-07-08
Abstract: PURPOSE:To ensure easy and reliable adjustment for cutting tool center height by providing a contactor at a position with which the edge of a cutter gets in contact, and a detecting slope formed aslant upward or downward for a datum plane orthogonal with the machining direction of the cutting tool. CONSTITUTION:When the edge of a cutting tool mounted on a numerically controlled tool rest is made in contact with the datum plane 44 of a contactor 40 at the tip of a housing 20, said contactor 40 moves finely to push the sensing part 33 of a contact detecting sensor 30, thereby turning 'ON' the sensor 30 and detecting a distance Z1 from a machining datum O, which position agrees to the horizontal center line a of a detecting slope 46. Then, the detecting 46 is contacted by a cutter edge and if said edge improperly contacts a point b due to misalignment, the sensor 30 begins to work and the position of the point b is measured as a distance Z2 from the machining datum O. The value of Z1-Z2 is a deviation in an X direction, but as the inclination of the detecting slope is 45 deg., it is possible to measure said position as a deviation S=Z1-Z2 for center height. If the cutter is lowered by a distance corresponding to the deviation, therefore, an error of center height can be made zero, thereby improving accuracy.
