Title: Manufacture of electric charge transfer device
Inventor: HATANO KEISUKE
IPC: H01L21/266
Filed: 1996-03-29
Abstract: PROBLEM TO BE SOLVED: To attain the setting of the size of a charge storage region and a potential barrier region arbitrarily, by etching every other junction part of an N-P type polycrysrtalline silicon layers to separate each other. SOLUTION: An N type plycrystalline Si layer 107 is formed by ion implanting phosphorus to a polycrystalline Si film 104 using a photo resist film 106 having a first opening as a mask. A second oxide silicon film 108 is formed selectively with a liquid phase growth method using the photoresist film 106 as the mask. After removing photo resist mask 106, and a P type polycrystalline Si layer 109 is formed with self-aligning the N type polycrystalline Si film 107 by ion implanting boron that is the reverse conductive type of the N type polycrystalline Si film 107 to the polycrystalline Si film 104. After removing the first and second oxide Si films 105 and 108 by etching, two different conductor type polycrystalline Si layers 107a and 109a are jucntioned by etching the junction part and its vicinity of the N type and P type polycrystalline Si layers 107 and 109 using formed photo resist film 110 as the mask.

Title: Method of and device for variable speed traverse
Inventor: OOTSUKA IWAO
IPC: B65H54/28
Filed: 1981-05-19
Abstract: PURPOSE:To form the surface of a taken-up thread member into a tapered shape by using a traverser driving motor and a variable speed motor rotatable in both normal and reverse directions. CONSTITUTION:Tapered bobbins 16 are fixed to the shafts of torque motors 15, all in the same direction with respect to a traverser, and a variable speed moror 1 is used as a traverser driving motor. The speed of the motor 1 is increased at  a constant rate by a suitable control circuit as link levers 8 move in the directions toward the small diameter sides of the tapered bobbins 16, but is decreased at a constant rate as they reversely move in the directions toward the large diameter sides of the bobbins 16. With this arrangement, the thread member may be taken up in a properly tapered shape even if a tapered bobbin is  used as each bobbin 16, thereby the phenomenon of surface avalanche is hardly  caused and the threaded member 12 can be smoothly rewound.

Title: Digital signal reproducer

IPC: H03M13/00
Filed: 1984-04-13
Abstract: PURPOSE:To make the best use of the correcting capacity of a code and to improve the correction reliability by adding a decoding end detecting means and an informing means to a decoder and delivering the information when the coding is not finished within a data interval. CONSTITUTION:An error correcting circuit 2 starts decoding with a signal (c) given from a synchronizing signal generating circuit 6 and applies a signal (d) to a decoding end detecting circuit 3. The circuit 3 checks whether or not the decoding is through with the signal (d) and then sets a signal (e) at logic ''1'' when the decoding end is detected. For a pulse detecting circuit 4, the signal (e) is set at logic ''1'' in a pulse period of the signal (c). Thus a digital signal (f), i.e., the output of the circuit 4 is kept at logic ''0''. The signal (e) is kept at logic ''0'' before the coding is over. While the signal (f) is set at logic ''1'' for a fixed period of time at the circuit 4 since the signal (e) is not set at logic ''1'' for a pulse period (cycle T) of the signal (c). An informing circuit 5 receives the signals (f) and informs other functions that the correction was impossible with the code words for the pulse period.

Title: Magnetic reproducer
Inventor: MINO MINEO
IPC: H04N5/7826
Filed: 1980-06-03
Abstract: PURPOSE:To keep the running speed of a tape constant, by setting the gain of the speed control loop of a motor. CONSTITUTION:Information on a tape speed is obtained by reproducing a control signal, recorded on a tape 3, by a head 9 and then supplied to a frequency dividing circuit 30. The oscillation frequency (f) of a reference oscillator 31 is compared with the control signal by a phase comparator 32 to obtain a phase error signal. When playback operation is carried out with the tape speed W times as fast as the speed in the recording of the control signal, the reproduced control signal increases frequency accordingly. Then, the phase error signal is applied via a mixer 27 to a motor driving circuit 28 to form a phase control loop, and the control signal synchronizes with the signal of the oscillator 31, holding the tape speed constant.

Filed: 1981-05-19
Abstract: PURPOSE:To raise the efficiency of a dynamic seal, by forming a dynamic seal section consisting of a pattern of grooves having a small depth at the suction side of a side plate so as to exert the function of dynamic seal effectively, and reducing the amount of leaked fluid by omitting the grooves of the dynamic seal section at the discharge side of the side plate. CONSTITUTION:Leakage of fluid Qc from a ring-like groove 56 to a low-pressure vane chamber 52 is prevented by a dynamic seal section 57 consisting of spiral grooves. The dynamic seal section 57 is formed as a pattern of grooves having a small depth that are formed in a side plate 53 at its suction side in the manner that the gap to the relative sliding surface of vanes 53 is changed. That is, the function of dynamic seal is exerted effectively since the leaked fluid Qc is a viscous fluid consisting of oil admixed with a cooling medium. At the discharge side of the side plate 53, on the other hand, the amount QA of leaked fluid can be rather reduced by omitting the grooves since the leaked fluid QA is almost in the state of gas.
