IPC: H04B7/08
Filed: 1989-06-07
Abstract: PURPOSE:To use the antenna for both diversity reception and nondiversity reception by devising the antenna such that a matching device capable of using a synthesis signal of received signals of both antennas as an antenna signal is freely mounted between feeding points of those two antennas having a directivity different from each other. CONSTITUTION:When the antenna is used with a radio receiver provided with a diversity receiving function, two antennas 18, 19 whose directivity differs from each other provided on the same glass pane 17 are directly connected to two input terminals of the receiver side.

Title: Picture recorder
Inventor: SATO YOSHIAKI
IPC: H04N1/21
Filed: 1993-05-25
Abstract: PURPOSE:To improve operability and usability by recording corresponding relation between picture data and sound data in a control file for recording sub-information data relating to the picture data or the sound data as sub- information. CONSTITUTION:When switches 13E, 13F respective indicate reproduction and sound, a system controller 8 reads out a corresponding picture file name stored in a sound file header and reproduces a picture and its corresponding sound file. When the switches 13E, 13K respectively indicate reproduction and a program, sound files I to III correspoding to every respective pictures I to III selected and reproduced in accordance with the program stored in a control file are reproduced. When there is no corresponding picture file name in the sound file header, only the sound file is reproduced. Thus a mode for simultaneously and continuously reproducing the contents of both a sound file and a video file can be attained by simple operation. Since both the sound and video files are collected as one file, succeeding reorganization can easily be executed.

Title: Charge coupled device
Inventor: ONO HIDEYUKI
IPC: H04N5/335
Filed: 1991-06-18
Abstract: PURPOSE:To eliminate a sensitivity changeover switch by a method wherein an output circuit is provided with the holding region of a signal charge and the potential of the holding region of the signal charge is distributed in a step shape. CONSTITUTION:An N-type layer 120 which is depleted by a voltage which is lower than a reset drain voltage VRD is formed. Then, when a signal charge amount is made small and a sensitivity is made high, a signal charge Q is accumulated in a floating diffusion layer 11 whose capacity is small. Then, when the signal charge amount is made large and a dynamic range is required, a signal charge Q' is accumulated in the floating diffusion layers 11 and 120, and the capacity of the floating diffusion layers can be increased. Consequently, the substantial capacity of the floating diffusion layers executing a charge-to- voltage conversion operation can be increased without installing a sensitivity changeover gate electrode as the signal charge amount is increased. As a result, when the signal charge amount is small, a sensitivity can be increased; when the signal charge amount is large, the dynamic range can be increased.

Title: Power converter for driving of permanent magnet type motor
Inventor: ENDOU TSUNEHIRO
IPC: H02P6/00
Filed: 1980-10-20
Abstract: PURPOSE:To prevent reduced magnetism owing to overcurrent of a permanent magnet by making a switching element turned ON when current flowing through a power converter exceeds a first set value and turned OFF when it exceeds the second set value. CONSTITUTION:Three-phase AC is applied to an armature winding 6-1 of a permanent magnet type motor from a DC/AC converter 5 while DC of the converter 5 is detected with a current detector section 8, the outputs VId of which are applied to comparators 10 and 11. They are compared with a set value VI1 smaller than the allowable maximum current value of a switching element TR through the comparator 10 and with a set value VI2 smaller than the allowable maximum value of current flowing through the armature winding 6-1 without reducing magnetism of a permanent magnet 6-2 and signals S21-S26 are generated to turn OFF or ON the switching element TR. This prevents the flowing of overcurrent due to the breakdown of a transistor thereby avoiding the reduced magnetism of the permanent magnet 6-2.

Title: Manufacture of semiconductor device
Inventor: FUCHINO FUMIHIRO
IPC: H01L21/768
Filed: 1996-05-16
Abstract: PROBLEM TO BE SOLVED: To provide a method for manufacturing a semiconductor device, by which any size of holes can be perfectly buried while an aluminum film can be made thin. SOLUTION: Aluminum films 8 and 9 are sequentially formed on an insulating film 5 by a sputtering process, and then a semiconductor substrate 1 is subjected to an annealing process for 20-60 seconds at a temperature of 450-530 deg.C. Even when a void 11 takes place within a hole 6 during the formation of the second aluminum film 9, the void 11 can be eliminated by the above annealing process. Further, since the above annealing process is carried out continuously within an identical chamber after the formation of the aluminum films 8 and 9, there can be avoided such a disadvantage that the surfaces of the aluminum films are oxidized. Accordingly, the aluminum films can be made thick, and at the same time, any size of holes can be perfectly buried, thus improving electrical characteristics and reliability of a resultant semiconductor device.
