Title: Ventilating device
Inventor: SHIMIZU HIDEAKI
IPC: F24F13/10
Filed: 1997-06-12
Abstract: PROBLEM TO BE SOLVED: To prevent twisting and deflection at a driving operation part and to switch a front panel with equal spacing from a front cover by providing the driving operation part with an elastic body and an operation part for switching the front plane from a case body by the driving operation part. SOLUTION: Elastic bodies 33c1 and 33c2 that are nearly U-shaped springs are formed at arm parts 32c1 and 32c2 of a driving operation part 32. When a blower 12 is operated, a motor 19 rotates and a wire 22 pulls a recessed part 20a of the driving operation part 32 nearer, thus rotating the arm parts 32c1 and 32c2 counterclockwise and operating an operation part 21a (21b) by contact parts 20d1 and 20d2 for opening a front panel 18 from a front cover 13. When the blower 12 is stopped, closing operation is similarly performed. In the such operation of a panel-switching mechanism 31, even when the driving operation part 32 is hot accurately manufactured, twisting and deflection the driving operation part 32 are prevented by the elastic force of the elastic bodies 33c1 and 33c2 being formed at the driving operation part 32, thus uniformly opening the front panel 18.

Title: Qam demodulator
Inventor: KAWANAKA ZENICHI
IPC: H04J1/00
Filed: 1995-05-31
Abstract: PURPOSE: To demodulate a modulating signal by detecting a synchronization symbol from a position of the symbol at which the result of product sum operation between the amplitude error and the phase error has a minimum value so as to correct the phase thereby conducting phase correction based on detection of accurate synchronization with a simple configuration and operation. CONSTITUTION: A regeneration circuit regenerate a symbol timing signal nearly synchronously with a symbol timing of a transmitter side. An AGC circuit 10 extracts M-sets of higher amplitude values for a prescribed period as to each amplitude of symbol signals when M-sets of synchronization symbols and pilot symbols decided to take a maximum amplitude for a prescribed period are in existence to adjust the gain. An error detection circuit obtains an error of a synchronization symbol with respect to an amplitude and an error of the synchronization symbol with respect to a phase respectively as to each of S-sets of optional consecutive symbols when S-sets of synchronization symbols are in existence for a prescribed period. A minimum value detection circuit detects a symbol in which result of product sum between the amplitude error and the phase error is a minimum value.  Then the synchronization symbol is detected from a position of the symbol providing the minimum value as above to correct the phase.

Title: Fm multiplex transmitter
Inventor: KURODA TORU
IPC: H04J4/00
Filed: 1987-06-24
Abstract: PURPOSE: To transmit PCM sound signals and data signals, by encoding the PCM sound signals and data signals with (272, 190) codes and successively transmitting the encoded signals in a direction oblique to the encoding direction.  
     CONSTITUTION: After sending out a framing code (FC) 201 and mode control code (MC) 202 as they are, signals are fetched one bit by one bit in the oblique direction from the upper left corner to the lower right corner as shown by the arrows and sent. Namely, one frame is completed in such a way that signals are sent along the arrow 301 first and, while the signals move rightward, the sending path is moved from the 302 to 303, and finally, the sending path is moved from the 304 to 305. Thus bit signals are successively fetched and transmitted in the oblique direction which is different not only from the longitudinal direction, along which the sound signal sample of a sound signal section 203 is arranged, but also from the transverse direction, along which PCM sound signals and data signals are encoded with (272, 190) codes. Therefore, the PCM sound signals and data signals can be transmitted simultaneously.

Abstract: PURPOSE:To make it possible to adjust an output pulse width and pulse interval by eliminating the trailing edge of a code pulse by finding AND between the final output and an output one stage before of a shift register. CONSTITUTION:By gate signal (a), oscillator 1 supplies clock (b) to shift register 2 and parallel input 3 is so set that final output Qn9 of register 2 will be pulse (c).

Abstract: PURPOSE:To make the titled reader small in size without using a condensing body of large size and complicated shape, and to improve the condensing efficiency placing a photomultiplier tube having a photodetecting surface extended along a main scanning line as a photodetecting means, in the vicinity of a sheet. CONSTITUTION:Excitation light 1a which has been emitted from an excitation light source 1 is made incident on a galvanometer mirror 2 and reflected and deflected, and executes a main scan in the direction as indicated with an arrow A on an accelerated phosphor sheet 3 which is carried in the direction as indicated with an arrow B by an endless belt device 9 being a subscanning means. A scanning position on the accelerated phosphor sheet 3 to which the excitation light 1a has been irradiated emits accelerated light in accordance with image information which has been accumulated and recorded therein. This accelerated luminous light is detected by a long-sized photomultiplier tube 5, and converted to an electric signal.

Title: Intrusion supervisory unit
Inventor: SASAGAWA KOICHI
IPC: H04N7/18
Filed: 1991-06-27
Abstract: PURPOSE:To reduce the influence of the external environment variance for an intrusion supervisory unit applying a digital image processing technique by extracting the low frequency component out of an input image through an LPF part and eliminating the low frequency component through a 2nd difference processing part. CONSTITUTION:When a mobile object emerges on an input image G sent from an A/D converter 2 and a low frequency component is applied to the density level of a background due to an external environment variance, the influence of the external environment variance emerges on the output D1 of a 1st difference processing part 41. Then a binary image is obtained due to the mobile object and the external environment variance as the output B1 of a 1st binarization processing part 51. Meanwhile only the low frequency component of the background emerges on the output F of an LPF part 6, and the parts of the mobile object and a static objects are reduced for the output D2 of a 2nd difference processing part 42. Then a binary image consisting of the mobile and static objects is obtained as the output B2 of a 2nd binarization processing part 52. A logical arithmetic part 7 secures an AND between both outputs B1 and B2 and defines the output R as a binary image of a mobile object only.

Title: Magnetic sensor
Inventor: TAGAWA MASATAKA
IPC: F15B15/28
Filed: 1991-06-27
Abstract: PURPOSE:To reduce the contribution of resistance change of a compensation element pattern, by surrounding a compensation side element pattern by using high permeability material to bypass magnetic flux, interposing an insulating film at the upper part or the lower part of the compensation side element pattern, and bypassing magnetic flux by using high permeability material. CONSTITUTION:A magnetic flux bypass pattern 6 is formed so as to surround a compensation side element pattern. Magnetic flux entering the compensation side element pattern 1 is positively bypassed by the magnetic flux bypass pattern 6, which exhibits the effect restraining the change of resistance value of the compensation side element pattern 1. Hence the contribution of the compensation side element pattern 1 to the output is reduced, and the contribution of resistance value change of a sensitization side element pattern 2 is increased. When a magnetic sensor constituted like this is used for piston position detection, the detection range of piston head position can be extended.

Title: Current source
Inventor: ISHIHARA TSUTOMU
IPC: G05F3/24
Filed: 1980-11-07
Abstract: PURPOSE:To obtain a current source of a high output resistance, by providing the second MOSFET between an output terminal and the source of a D type MOSFET constituting a current source. CONSTITUTION:An E type MOSFET12 where the gate is connected to the drain is connected between the source of a D type MOSFET11 and an output terminal 20. The gate of the D type MOSFET11 is connected to the output terminal 20, and the drain is connected to the other output terminal 30. When the voltage across terminals 20 and 30 becomes higher, the current flowed to the FET11 tends to rise by the influence of the channel length modulation effect; however, the increment of this current increases the voltage drop of the FET12, and the voltage between the gate and the source of the FET11 is reduced to suppress the increment of the current.
