Title: Video signal recording system
Inventor: HIROTA AKIRA
IPC: H04N5/7826
Filed: 1979-08-17
Abstract: PURPOSE: To obtain the picture less in the crosstalk and excellent in S/N, by detecting the rotating phase error of the rotating head produced at recording and controlling the magnetic tape according to the phase error voltage obtained from this signal and the reference signal.  
     CONSTITUTION: The phase error voltage is fed also to the phase modulator 13. On the other hand, the rotation detection signal of frequency proportional to the rotating speed of the capstan 14 via the frequency generator 16 is fed to the phase modulator 13 via the frequency divider 17. The phase modulator 13 outputs pulse with the phase error voltage from the phase comparator 4 and the rotation detection signal from the frequency divider 17 and it is fed to the phase comparator 19 as the comparison signal. The phase comparator 19 compares the reference signal from the reference signal generating circuit 20 with the comparison signal to output the phase error voltage according to the phase difference so that the revolution speed of the capstan motor 22 is made constant and the rotation phase is also controlled according to the phase error voltage. With this constitution, the picture less in the crosstalk and excellent in S/N can be obtained.

Title: Dark current noise removing device
Inventor: TANAKA SEIICHI
IPC: H04N5/353
Filed: 1998-04-15
Abstract: PROBLEM TO BE SOLVED: To provide a dark current noise removing device having a reduced memory capacity for an image-pickup element. SOLUTION: A dark current noise component the image of which is picked up with a shutter 16 closed is compressed and stored in a memory 4, and subtracted by a subtracting circuit 5 from a normally picked up and compressed image signal to remove dark current noise. Thus, the dark current noise component is compressed to decrease the amount of information as compared with that before compression, thereby enabling reduction in the capacity of the memory 4 for information storage.

IPC: G10H1/18
Filed: 1994-04-21
Abstract: PURPOSE:To obtain the electronic musical instrument that even a beginner can handle by performing timbre process!ing by performing control according to plural parameters obtained through the operation of plural operation elements given names showing abstract feelings that a player has for timbres. CONSTITUTION:The electronic musical instrument is equipped with plural operation elements 6 given the names showing the abstract feelings that the player has for the timbres, a parameter conversion table 15 corresponding to the operation elements 6, and a tone generator 8 which performs the timbre processing by performing the control according to the parameters corresponding to the operation of the operation elements 6.

Title: Package for integrated circuit with heat radiator
Inventor: ATSUME YOUKO
IPC: H01L23/28
Filed: 1988-04-26
Abstract: PURPOSE:To enable a large quantity of heat dissipation by a heat radiator of the same size, to scale down the heat radiator and to increase strength to transverse stress remarkably by giving corrugation to the contact surfaces of the heat radiator and a package. CONSTITUTION:The heat-radiator loading-section surface of the central section of the top face of a package 1 is machined to corrugation. A loading surface 2a to the package of a heat radiator 2 loaded is machined to a corrugation in complementary relationship to the projecting sections and recessed sections of the corrugation of the loading section of the package. Consequently, the mutual contact surfaces 1a, 2a of the package 1 and the heat radiator 2 loaded onto the package 1 are fast stuck in wide areas. Accordingly, heat is transferred efficiently to the heat radiator from the package and, further, dissipated to the outside air, thus inhibiting the temperature rise of the package 1.
