Title: Digital audio recording and reproducing device
Inventor: TSUJI SHIRO
IPC: H04N5/92
Filed: 1990-02-22
Abstract: PURPOSE:To obtain a reproducing audio signal with high quality without generating the overflow or underflow of a reproducing memory by operating a readout address counter with a prescribed internal cycle and performing the timing control of the number of samples in a state where reproduction at slow speed in which no update information is detected is performed or a device is in a standstill state. CONSTITUTION:An audio signal read out from a field memory 21 in slow reproduction is written on a specific reproducing memory 28 in unit of field via a correction circuit 27. Since the signal of the same field is reproduced for N times by performing the reproduction at slow speed of 1/N times, only the signal at the leading field is written on the specific reproducing memory 28, and in readout, the time base of the readout is expanded with a readout address in which a clock with cycle of N times is set as a base from a jog memory controller 29. Furthermore, the supplementation of remaining (N-1) samples when expansion of N times is performed is performed by interpolating by filtering processing with an interpolation filter 30 using a DSP, which improves the quality of the reproducing signal.

Title: Distributor
Inventor: TAKAGI YASUO
IPC: F02P15/08
Filed: 1978-04-10
Abstract: PURPOSE:To prevent the increase in noises due to the excessive combustion of a two-point-ignition engine, by providing a distributor which substantially shifts the two-point ignition of the engine to one-point ignition when the load upon the engine is high. CONSTITUTION:A fixed plate 3 made by laminating semicircular ignition spark advancing plates 6, 5 with each other is provided in a casing 1. A rotor shaft 2 extends through the fixed plate 3 so that the plates 5, 6 can swing independently of each other centering the rotor shaft 2. The plate 5 is coupled to a diaphragm unit 7, which is actuated by a negative pressure which varies depending on the running condition of the engine. The plate 6 is coupled to a diaphragm unit 9, which is actuated by the intake negative pressure f the engine. When the load upon the engine is high, the difference between a first and a second ignition phases is increased. At that time, the combustion based on the first ignition is finished if the second ignition is effected. The two-point ignition is thus substantially shifted to the one- point ignition.

IPC: B41M5/00
Filed: 1978-03-30
Abstract: PURPOSE: To let printing be readily accomplished on various materials by letting the ions deposited with ink particles pass through a net form electrode and letting the same be deposited on print member.  
     CONSTITUTION: High voltage is applied between a positive electrode 1 and a negative electrode 2 to generate ion current and a vibrator 9 is vibrated to mist ink 7. The ink mist is then diffused by the air current of an air path 10. When the voltage by which positive ions are accelerated is applied to the selective electrode 5c and common electrode 4b of an aperature board 5, the positive ions pass through the through-hole of the aperture board 5 and enter the ink mist 8, where they are deposited with ink particles. The accelerated positive ions pass through the net form negative electrode 2 and deposit in dot form on the print member 3. Hence, by letting the controlling of the electrode 5c be main scanning and the feeding of the member 3 be sub-scanning, the specified characters are printed.

Abstract: PURPOSE: To obtain a semiconductor device which prevents fluorine from being implanted into a gate interconnection and which suppresses an interlayer insulating film grown on it from being stripped by a method wherein, when p-type ions are implanted, a resist mask which covers a p-channel FET and the gate interconnection is formed. CONSTITUTION: An implantation, mask for formation of the diffusion layer of a p-channel FET 1 is a resist mask 5A which covers an n-channel FET 2 and a part of a gate interconnection 3. It does not have an area which is required as a minimum in order to increase the opening area of the resist mask, and a region which has a dislocation margin for a lithographic process in the intermediate point between the p-channel FET 1 and the n-channel FET 2 in a gate interconnection 3 is covered with the resist mask. In addition, an implantation mask for formation of the diffusion layer of the n-channel FET 2 is a mask 4A which covers the p-channel FET 1 and a part of the gate interconnection 3, and it covers a region which has a dislocation margin in the same manner as in the case of the p-type.  Thereby, it is possible to prevent an interlayer insulating film on the gate interconnection 3 from being stripped due to the discharge of implanted fluorine.
