Title: Regenerative fm signal demodulator
Inventor: TSURUMURA KOUJI
IPC: G11B20/06
Filed: 1993-10-18
Abstract: PURPOSE:To prevent the generation of noise and the deterioration of an S/N by easily eliminating a residual FM component by passing a regenerative FM signal input through a primary high-pass filter and a primary low-pass filter whose cut-off frequencies are equal. CONSTITUTION:A regenerative FM signal input passes through a primary high- pass filter 21 and a primary low-pass filter 23 whose cut-off frequencies are equal thereby both output signals have the phase difference of 90 deg. over all band ranges. Since two signals are multiplied by an operational amplifier 25, the frequency of the regenerative FM signal is doubled and then inputted to an FM signal demodulating circuit 12. In such a manner, even though a residual FM component is generated at the time when the FM signal demodulating circuit 12 demodulates the output signal of the operational amplifier 25 and outputs a demodulated video signal, the residual FM component has frequencies four times as many as frequencies of an original signal. Thus, elimination processing by residual FM component processing low-pass filters 13, 15 are easily performed.

Title: Molding die
Inventor: KOYAMA YUTAKA
IPC: H01L21/56
Filed: 1987-10-14
Abstract: PURPOSE:To prevent resin from exuding onto a frame and onto a metal die by improving the accuracy for each surface by coating the metal die partaing surface with the resin. CONSTITUTION:Resin (silicone) coating 5 is applied on a metal mold, whereby a metal die pertaing surface can accommodate the deformation of the metal die and the unevenness of a frame surface to some degree. Namely, the upper die 1, a lower die 2, and the frame 4 are completely brought into close contact with each other by a resin coated surface upon closing the die. In addition, when it is primarily desired to prevent the resin from exuding onto the frame surface, the resin (silicone) coating may be applied only on the lower die on which the frame is set and only the upper die with which the frame surface makes contact. Hereby, the accuracy of the surface contact between the dies 1, 2 and the frame 4 can be improved and the resin can be prevented from exuding onto the frame 4 and onto the dies 1, 2.

Title: Printing controller for image printer
Inventor: ADACHI KOZO
IPC: H04N1/23
Filed: 1986-10-31
Abstract: PURPOSE:To minimize the power consumption of an image printer and to reduce the capacity of a power source by reducing black data included in data corresponding to a solid black original image in an image memory if image data that an image detection part detects corresponds to the solid black original image. CONSTITUTION:If an original image 2 is black and solid or the image detection part 1 is troubled, a detection signal from a solid black image detection part 10 continues during a period T that a timer 11 sets. Then the output of an AND between the detection signal form the black solid image detection part 10 and a time-up signal from the timer 11 shows up, and a control signal is outputted to the image memory 3 from an image memory control part 13. Hence the ratio of the black data accounting for the data corresponding to the number of solid black scan lines set in the image memory 3 decreases, and image data as is found decreased is transmitted to a printer 5. It prints images having reduced black picture elements rather than its original (images printed by dots and lines and images of half tone, for instance). Thus the capacity of the power source in the image printer can be reduced.

Title: Method for fixing film negative on belt for conveying negative
Inventor: HACHIMAN MAKOTO
IPC: G03F9/00
Filed: 1988-10-14
Abstract: PURPOSE:To prevent a film negative from getting in the way when a next film negative is fixed, to make the after treatment of an adhesive tape unnecessary and to save such trouble by fixing the film negative on the lower surface of a belt for conveying a negative through the notched parts of the belt for conveying a negative with the aid of the adhesive tape. CONSTITUTION:The adhesive tape 12 is stuck on the upper surface of the belt for conveying a negative 7 having the plural notched parts 8. Then, by pressing it, the film negative S is fixed on the lower surface of the belt for conveying a negative 7. Therefore, in case that the used film negative S is removed from the belt 7, it is enough only that the belt 7 and the film negative S are mutually separated. At this time, since the adhesive tape 12 is still left on the upper surface of the belt 7, it is enough only to press the adhesive tape from the upside when the new film negative is fixed. Thus, the trouble when the adhesive tape is treated afterward is made unnecessary.

IPC: G11B20/12
Filed: 1990-10-01
Abstract: PURPOSE:To improve the preservable property of information by prohibiting the use of a sector which is not only having a defect or an error but also may have it in future. CONSTITUTION:Defect detectors 27 and 28 compare output levels of an addition amplifier 22 and slice level variable units 25 and 26. When there is the output of the addition amplifier 22 exceeding the output signal level of the latter, a defect signal is outputted. A track counter 31 and a sector counter 32 detects the track number and the sector number of a detection part. A registration sector setting circuit 33 designates the sector of the track where the defect is detected or the sectors of one or plural tracks adjacent to the track are designated. The number of the tracks to be designated can arbitrarily be set. When the size of the initial defect is set to be E, (number of tracks), the rate of the detect or the error which is enlarged in the number of stored years, namely, a multiplication rate is set to alpha, the range of alphaXE is registered as a defective sector. Thus, a data reproduction defect can be prevented and the preservable property of information can be improved.

Abstract: PURPOSE:To stably and surely control a BPF by forming an oscillation circuit so as to integrate the BPF automatically when a frequency of a reference signal and a frequency of the BPF are deviated. CONSTITUTION:When an input signal is a chrominance signal, a switch 14 is thrown to the position of a contact 14b so as to give an output of an adder 18 to a BPF 12 for a period between the chrominance signal and a burst signal.

Abstract: PROBLEM TO BE SOLVED: To display information regarding wind direction and speed on a monitor by using information on change in the driving current of a motor that changes due to the effect of wind being received by an antenna and information on the rotary position of the motor, and by detecting the wind direction and pressure of a place where the antenna is installed. SOLUTION: The current direction of an antenna 10, namely, an azimuth angle direction that is at right angle to a micro radiation surface, can be obtained according to information from an encoder 14, a motor driving current waveform is detected by a current waveform detection circuit 15, and hence a wind direction can be detected by detecting the position of the antenna 10 where the drive current is maximized. Also, since the driving current becomes the maximum when the opposite side of the radiation surface of the antenna 10 is located at the same position, the wind direction is detected by a wind pressure switch 11 being provided on the radiation surface only when the radiation surface receives the maximum wind pressure.  The current wind speed is detected by judging which waveform being stored in a current waveform storage table 17 the maximum current waveform being detected by the current waveform detection circuit 15 is matched with. Obtained information on wind direction and speed is sent to an indicator part 3 and is displayed on a monitor 30.
