Title: Sound reproducer
Inventor: TERAI KENICHI
IPC: H04S5/00
Filed: 1981-11-20
Abstract: PURPOSE:To get a listener to perceive sound image of arbitrary position, by providing 2n-set of speakers and equalizers to n-listener and setting the equalizer output so that the sound pressure of both ears from the speakers and can be equal to that from a specific speaker. CONSTITUTION:Speakers 8a-8d and equalizers 10a-10d are provided for listener 13, 14 and a virtual specific speaker 11 is provided at a position localizing the sound image. Impulse response sample trains from the speakers 8a-8d to both ears of the listeners 13, 14 are measured and those from the speaker 11 are measured. The tap coefficient of convolver is obtained from both the measuring values and given to coefficient devices 151-15m of a convolver circuit, coupled with delay elements 181-18m and an adder 28 to realize equalizers 10a-10d. Thus, the sound pressure of both the ears of the listeners 13, 14 in inputting a signal to input terminals 9 and 12 is the same, and even if the signal is inputted to the terminal 9, the listeners 13, 14 can perceive the sound image at the location of the speaker 11.

Title: Semiconductor photodetector
Inventor: WATANABE ISAO
IPC: H01L31/107
Filed: 1989-07-19
Abstract: PURPOSE:To realize an avalanche photodiode which is more excellent in a low-noise characteristic by a method wherein one part of an avalanche multiplication region of an electron-hole separation type is constituted of at least two or more kinds of binary-semiconductor minor-cycle superlattices in order to easily ionize carriers on one side. CONSTITUTION:A narrow-gap semiconductor layer 2 is constituted of a binary- semiconductor minor-cycle superlattice (InAs)m/(GaAs)m, (where m=1 to 2). Out of photocarriers, electrons are separated spatially to a narrow-gap binary semiconductor minor-cycle superlattice semiconductor A layer 2 and holes are separated spatially to a wide-gap mixed-crystal semiconductor B layer 3, respectively. When the narrow- gap A layer 2 is constituted of a binary-semiconductor minor-cycle superlattice of the same kind and same composition, a mixed-crystal scattering is suppressed and an energy loss of electrons is bard to cause; as a result, an ionization rate is increased remarkably as compared with a case where the layer 2 is constituted of a mixed-crystal semiconductor. On the other hand, the holes are subjected largely to the mixed-crystal scattering and the ionization rate remains low because they travel in the wide-gap mixed-crystal layer 3. Consequently, an alpha/beta ratio can be improved by several times as compared with conventional cases where the narrow-gap layer A2 is constituted of a mixed crystal.

Abstract: PURPOSE:To execute at a high speed a processing for reduction and magnification by constituting so that a mapping pattern for showing a position of information to be extracted when picture information is reduced, and showing the number of times for copying the information when said information is magnified are stored in a register. CONSTITUTION:A mapping pattern P is constituted of a vector whose component is ''0'' or ''1'', and for instance, in case of length : width =5:8, P=(P1-P8)= (1, 0, 1, 1, 0, 1, 1, 0) is obtained from an intersection point of a straight line 3 and a lattice line. The mapping pattern P and an original picture data Xi are stored in a shift register 71 and 72, and driven by clocks (c), (b) and (a) whose phase is delayed a little. By the clock (c), the original picture data of the re- gister 72 is shifted to the left, a data X1 of the left end is stored in a buffer 73, and when an output (d) of the register 71 is ''1'' by the next clock (b), the data of the buffer 73 is outputted and written in a register 76, and it is not written at the time of (d)=''0''. It is repeated and the picture is reduced to X1, X3, X4, X6 and X7. When magnifying it, only at the time of d'=''1'', an original picture cegister is shifted, X1, X1, X2, X2, X3 X4 and X5 are obtained from the data X1-X5, and reduction and magnification and magnification are executed easily.

Filed: 1984-09-10
Abstract: PURPOSE:To shorten the shift time of a record/reproduction transducer needed among many tracks and to increase the executing speed of an electronic computer, by moving a steel belt with the signal given from a controller. CONSTITUTION:The control signals are applied to steel belt shift means Mn-MO from a controller C, and a coupling member 12 moves with energization of a solenoid 13. Thus a pair of guide pins 11 and 11' are also moved. The number of shift means M is decided according to the number Nt of tracks. Then steel belts 6a and 6b, a carriage 4 and a record/reproduction transducer 2 are shifted. Then the shift amount of the means M is set at 2<n>-2O when the track pitch is set at 1. Therefore the transducer 2 is shifted to a desired track just with a single operation and by the combinations of control signals of the controller C.
