Title: Ofdm modulator
Inventor: MIYASHITA ATSUSHI
IPC: H04L27/36
Filed: 1997-06-19
Abstract: PROBLEM TO BE SOLVED: To provide an orthogonal frequency division multiplex OFDM modulator with which the compatibility in the use of sufficient frequency band and sufficient suppression of unwanted radiation is attained independently of the performance of a filter. SOLUTION: This OFDM modulator consists of an inverse Fourier transform circuit 81, a guard interval addition device 82, and an orthogonal processing section 3. In this case, an amplitude controller 1 which is a means revising an amplitude periodically is inserted between the guard interval addition device 82 and the orthogonal processing section 3, the amplitude for a period equivalent to a guard period which is an end of symbol on a time base is limited by output pulses PS, PE of a symbol end period generator 2 so as to reduce the level of an undesired leakage spectrum around a frequency-occupied band. Thus, the production of a side lobe is suppressed sufficiently to reduce an out-of-band leakage spectrum, then the dependence of a filter is sufficiently reduced, resulting in the elimination of the need for the use of an unpractical filter furthermore for the use of the filter.  Thus, the small-sized light weight OFDM modulator is easily provided at low cost.

Title: Electronic watch with alarm function
Inventor: YAMADA YOSHIKAZU
IPC: G04G13/02
Filed: 1979-12-14
Abstract: PURPOSE: To enable to realize a discrimination for the overlapped alarm tones, by producing successively plural different alarm tones based on the set priority.  
     CONSTITUTION: When the priority is set to the alarms AL1 and AL2 based on the time signal, the AND gates 44 and 45 are closed by the output Q' during the setting of the corresponding FF46 in the sequence priority control circuit 28 1 . The gate 45 is closed by the similar output Q' of the FF47. Accordingly, the set outputs of the FF46W48 are generated successively even in case the alarm time and the time of the time signal have overlapped each other. Thus the different alarm tones are produced successively based on the set priority via the different driving signal generating circuits. As a result, a clear distinction is made possible for the overlapped alarm tones.

Title: Ignition device for internal-combustion engine
Inventor: YAMATO KUNIHIRO
IPC: F02P7/03
Filed: 1985-07-23
Abstract: PURPOSE:To obtain precise ignition timing with a simple arrangement, by producing signals of different phases in the number equal to one-half of the number of engine cylinders of the sum of the number of the engine cylinder and one, from one ignition signal. CONSTITUTION:In the case of a four cylinder type reciprocating engine, when a first pulse of an ignition signal IN is applied to an input terminal 10, a transistor Q2 delivers pulses OUT2 to a trigger circuit 18. Accordingly, the trigger circuit 18 instantly cuts off current which has been fed until that time to the primary side 22P of an ignition coil 22 from a battery. As a result a high voltage is induced through the secondary side 22 of the coil to generate sparks at #2 and #3 spark plugs, and therefore, combustion is carried out in either one of cylinders associated with the spark plugs. Then, when a second pulse of the ignition signal IN is delivered, a high voltage is induced through the secondary side of an ignition coil 20 to generate sparks at #1, #4 spark plugs. thus, the ignition coils 20, 22 alternately generate a high voltage twice during the crank shaft rotating by two revolution, thereby it is possible to provide precise timing.

Abstract: PURPOSE:To increase an optical output essentially by using a polarized beam splitter for guiding back dispersed light from an optical fiber to a measuring part and a polarization eraser for passing laser light and the back dispersed light. CONSTITUTION:The polarized beam splitter 7 is shaped like a Foster prism and constituted of two calcite layers fixed each other at their connection surface 12 with cement.

Light dispersed to the back by a glass fiber is passed through the polarization eraser 8 in the reverse direction to the main direction 6 of the laser beam and arrived at the splitter 7 and about 50% the light is reflected by the connection surface 12 and sent to a measuring output 15 to increase the optical output.

Filed: 1998-06-11
Abstract: PROBLEM TO BE SOLVED: To surely attract and hold a disk onto a turntable without impairing the operability of a devices by providing a means for giving magnetic attraction force to a clamping plate of the disk and a means for controlling the magnetic attraction force. SOLUTION: Magnetic flux of a chucking magnet 1003 reaches the clamping plate 1042 via a core 1001, so that the disk 1023 is attracted and held onto the turntable 1028. At the time of removing the disk 1023 from the turntable 1028, a moving member 1004 is moved downward by operating an ejection switch, so that the chucking magnet 1003 recedes from the turntable 1028. Consequently, holding force of the disk 1023 onto the turntable 1028 can be reduced only at the time of taking out the disk 1023 without reducing the holding force itself at the recording and reproducing time, so that it is not necessary to strength spring force for jumping up a cartridge holder 1032, and hence the cartridge holder 1032 can be loaded by slight force.
