Title: Removing device for product adhered on heat transfer pipe surface
Inventor: YAMADA KOUJIROU
IPC: B08B9/02
Filed: 1987-11-11
Abstract: PURPOSE:To enable efficient removal of a product adhered on a heat transfer pipe surface by means of a low force without damaging a heat transfer pipe itself by a method wherein an ultrasonic vibrator is used as a tool, and the frequency of an ultrasonic wave and the shape of the supersonic vibrator are selected. CONSTITUTION:An electric signal generated by a frequency varying oscillator 6 is applied on a coil 4 for excitation, wound around a magnetortsictive vibrator 3, by means of a power amplifier 5. The magnetostrictive vibrator 3 is vibrated with the frequency of the oscillator 6, serving as a fundamental frequency, by means of the coil 4 for excitation. The shape of the tip of an ultrasonic hone 2 mode of a metal adhered on the vibrating surface of the magnetiostrictive vibrator 3 is properly selected according to the shape of an object and the content of a work. When the ultrasonic hone 2 is brought into contact with a product 7 adhered on a heat transfer pipe surface, a vibration power is concentrated to the projected part of the surface of the adhered product 7 to crush the projected part. A part of the crushed projected part performs a role of a kind of an abrasive as moving particles, and the quality of contact with the ultrasonic hone 2 is improved. As noted above, when ultrasonic vibration is exerted on two layers having different qualities, discontinuity occurs to vibration displacement at an interface between the two layers, and peel is apt to occur to the two layers.

Title: Surface observer
Inventor: SHIMURA TAKANORI
IPC: G01B15/08
Filed: 1987-11-11
Abstract: PURPOSE:To make a clear-cut image displayable at high speed by setting up a bit mask circuit, nullifying a bit inclusive of noise, in secondary electron data collector part, and installing a color lookup table circuit, capable of selecting optional several colors, in an image display part. CONSTITUTION:Prior to starting a data collection, a main control part 1 specifies a gain of a gain control part 15. A beam 5 is subjected to test scanning and, after gain setting is over, whether what degree of a noise component is in secondary electron data is checked. Next, the main control part 1 indicates a bit mask circuit 18 that how many subordinate bits should be nullified. With this indication, the bit mask circuit 18 removes the specified noise component. In addition, a color lookup table 27 specifies a display color corresponding to intensity of a secondary electron. When it wants to emphasize an optional part, this case will be done by rewriting of the color lookup table. With this constitution, the optional part on a sample can be emphasized and displayed by only collecting the secondary electron intensity data discharged out of the sample one time.

IPC: G07F9/10
Filed: 1992-10-22
Abstract: PURPOSE:To save power consumption by rigidly restricting flows of air in a stock and outside air at the time of replenishing merchandise to an automatic vending machine provided with plural merchandise racks. CONSTITUTION:Apertures 41 to be opened to individual projection ports 2a of respective merchandise racks 2 arranged in a stock are formed on respective inner doors 4 arranged in the front of the stock in a body case 1 and a fixing frame 42 is formed on the peripheral edge of each aperture 41. A flapper 5 is supported by the frame 42 so as to be rotated, normally exicted by a spring 52 so as to close the aperture 41 and opened by an injected merchandise 7 at the time of replenishing the merchandise 7. Since only the aperture 41 opposed to the injection port 2a into which a merchandise 7 is injected is opened only for the passage of the merchandise 7, the outflow of air from the stock can be extremely reduced.

Title: Optical scanning device
Inventor: NAKAYAMA KOJI
IPC: B41J2/44
Filed: 1989-10-31
Abstract: PURPOSE:To stably emit a light signal for a long period by providing a rotary part with a power generating means for driving a light emitting means. CONSTITUTION:When the rotary part 4 rotates, the magnetic field produced by a permanent magnet 13 provided to a fixed magnet ring 12 crosses the power generating coil 11 of the rotary part 4, an electromotive force is generated by the power generating coil 11, and the current generated with the electromotive force is used for the light emission of an LED 10. Electric power for driving the LED 10 as a light emission source for scanning light is supplied from the power generating coil 11 by utilizing the rotational power of the rotary part 4, so there is no defective contact between slide contacts of a fixed part and the rotary part. Further, when a signal is transmitted, a light signal (modulated light) obtained by converting an electric signal by a conversion part is sent and reconverted by a photodetecting element 9 into the electric signal, which is inputted to the LED 10, so the signal transmission is carried out without any contact between the fixed part and rotary part. Consequently, stable light emission can be secured and the reliability is improved.

Title: A/d converter
Inventor: DAIBO MASAHIRO
IPC: H03M1/36
Filed: 1992-09-30
Abstract: PURPOSE:To obtain high noise immunity and to improve the resolution at a high speed with high accuracy, by devising the A/D converter such that quantization at a voltage interval larger than a voltage interval equivalent to 1LSB is implemented to prevent an analog signal in the circuit from being too small. CONSTITUTION:A reference voltage at A/D conversion of high-order m-bits is given to a main reference voltage array 1 and its voltage interval Vsm is equivalent to 1LSB of a high-order A/D converter. A comparator 3 compares a reference voltage having the voltage interval from the voltage array 1 with an analog input voltage to generate a thermometer code. A high-order encoder 4 encodes the thermometer code and converts the code into a digital signal in high-order m-bit. The high-order m-bit A/D conversion is implemented corresponding to an amplitude of the analog input signal by combining the voltage array 1, the comparator 3 and the encoder 4. On the other hand, a vernier reference voltage array 2 whose voltage interval is Vsb (relation to the voltage interval Vsm is expressed in 2<n>Vsb=(2<n>-1)Vsm) is used for a reference voltage for low-order n-bit A/D conversion.

CONSTITUTION:When a new mold is placed on the non-directional bearing 53 of a mold support member 54, the pressure in the lower pressure chamber 68 of a hydraulic cylinder 51 rises to a prescribed value or more to be discharged from a relief valve 73. At this time, the centering member 57 connected to a piston rod 52 by a link 58 is pulled downwardly and parallelly moved in the center direction of a vulcanizing machine centering around the fulcrum pins 59 of parallel links 56 to push the mold on the bearing 53 toward the center of the vulcanizer. In the final stage, the centering in the circumferential direction of the mold is also performed by the aligning surface 63 having a V-shape cross-section provided to the inside surface of the centering member 57. When a change-over valve 69 is operated from this state to supply a pressure fluid for clamping to an upper pressure chamber 67, a lower mold 26 is fixed to the surface of a lower hot plate in a pressure contact state by a clamp pawl 64.

Filed: 1986-11-29
Abstract: PURPOSE:To secure the correspondence between the display position of a display device and the print position of a printer by detecting a specific function code and displaying it on a display device. CONSTITUTION:A data deciding control logic circuit 312 reads data out of a memory 40 storing data via the key input, etc. and controls the display of a display device. If the data read into a circuit 3 show the specific function codes for carriage return, line feed, half line feed, half reverse line feed and margin release respectively, these data are displayed on a display device and at the same time an address pointer 308 is not stepped. The following data equivalent to a single character is prevented by a gate G12 since the signal J received from a gate G11 is equal to '0' by the discordance output of a comparator 321 because the pointer 308 is not stepped. Thus said data is not fetched by a display buffer 306 nor displayed on the display device.
