Title: Recording system
Inventor: KAWAI JUN
IPC: H04N1/405
Filed: 1987-05-12
Abstract: PURPOSE:To improve the spatial resolution of a picture without changing a dot space in a recording system to obtain falsely a half tone picture with the aid of a binary area gradation reproducing method using a threshold matrix by combining and using >=two kinds of the threshold matrix in the order of an output density according to the respective output density characteristic. CONSTITUTION:In a thermal transfer recording device, a density pattern ROM 1 to output the dot data of 4X4 corresponding to a 6 bits density data, stores previously a dot pattern data. The density pattern ROM 1 inputs the 6 bits density data, i.e., a picture data, as a read-out address, and outputs the corresponding binary dot data of 16 bits. A head drive control part 2, as synchronizing with a clock signal from a timing control part 4, drives the respective heating elements of a hot melt transfer type thermal head 3 based on the binary dot data from the density pattern ROM 11. Accordingly, the number of the gradations can be drastically increased without changing the size of a unit matrix.

Title: Bimorph driving device
Inventor: TANAKA YOSHIHIRO
IPC: G03B9/10
Filed: 1987-05-11
Abstract: PURPOSE:To reduce frictional resistance at the time of actuating a bimorph driving element and to attain a high speed actuation by constituting a device in order that the contacting position of the bimorph driving element with a member to be moved by pressing does not change in substance even if the element turns. CONSTITUTION:The bimorph driving element 14 on which a voltage is impressed in a shutter closing state turns centering around an axis 14a and a switching lever 12 turns clockwise, then shutter blades 2 and 4 are turned in an opening direction by pressed to be moved by pins 12c and 12d holding the free end 14b of the element 14 between them. The element 14 and the pin 12c which contact each other at contact points 14A and 12A are made to contact at the contact points 14B and 12B by the turning of the element in a P direction, but the contact points 14A and 14B does not change in terms of the positions and the contact points 12A and 12B dislocate. But the value of dislocation can be neglected. Therefore the frictional resistance at the time of actuating the driving element can be reduced, so that the device can be actuated at high speed.

Title: Audio signal processor
Inventor: ODA MIKIO
IPC: H03M1/00
Filed: 1988-05-11
Abstract: PURPOSE:To suppress the fall of a dynamic range and the deterioration of S/N in a digital part, and to improve quality by controlling a level at an analog area according to the level of an audio signal to be inputted at the time of the occurrence of over-flow. CONSTITUTION:The audio signal to be inputted is converted into a digital signal by an analog-digital converter(ADC) 1, and inputted to a digital signal processor(DSP) 2. When the signal of the level higher than the prescribed input level is inputted, a level detector 7 controls an attenuator(ATT) 4, and since it attenuates the level to be inputted to a DSP operating part 5, the DSP operating part 5 can perform operational processing without causing the over-flow. Besides, the level attenuated by ATT 4 is corrected by a gain amplifier 6 of an analog part. Thus, the dynamic range can be expanded, and simultaneously, the high quality audio digital signal processing of good S/N comes possible.

Title: Antifungal composition
Inventor: TAKAHATA NORIO
IPC: C08L27/04
Filed: 1987-05-11
Abstract: PURPOSE:To obtain an antifungal composition which can prevent effectively the growth of molds, by adding a specified organoarsenic compound to a polymer comprising vinyl chloride and urethane. CONSTITUTION:An antifungal composition prepared by adding 10,10'- oxybisphenoxyarsine to a polymer comprising vinyl chloride and urethane. A PVC-based vinyl composition containing a plasticizer has heretofore been considered as having excellent properties. However, the use of a plasticizer have caused disadvantages such as softening, deformation, cracking, etc. by migration of plasticizer when it is in contact with, for example, a film of, e.g., a paint, a plastic material or the like or deterioration of properties due to volatilization or extraction of plasticizer. The above-mentioned disadvantages can be eliminated by ceasing the use of a plasticizer and using urethane. However, a problem of mold growth due to the urethane component has arisen. By the addition of said organoarsenic compound, the growth of molds can be prevented.

Title: Lead frame for integrated circuit
Inventor: CHIBA HIROSHI
IPC: H01L23/495
Filed: 1980-08-20
Abstract: PURPOSE:To prevent the deformation of two or more of inner leads, and to join the leads accurately and automatically by combining a small piece being fitted to the shape of the tips of the leads with the tips. CONSTITUTION:A small piece 5 with shape fitted to the side surfaces of the noses of the leads is combined with the center of a lead frame with conventional shape. When cutting the small piece 5, it is contacted previously with the leads without being cut down, and pushed back beforehand to the plate by a spring force in a lower die at the same time as the rise of an upper after cutting. Consequently, the lead frame can be mounted to a ceramic substrate while the lead frame is maintaining its positional dimensions of the press-punched time, and the small piece 5 can simply be removed by pulling it by utilizing the central hole 8 of the small piece. According to this constitution, defective positional displacement in an automatic bonder is not generated because the positional accuracy of the tips of the inner leads is extremely high.
