Title: Method for testing reliability of semiconductor element
Inventor: KOIKE NORIO
IPC: H01L21/66
Filed: 1994-11-30
Abstract: PURPOSE: To provide a method by which the dielectric strength of an oxide film in a semiconductor element can be tested with high accuracy in a short time. CONSTITUTION: While voltages are applied across an oxide film, the current density in the oxide film is measured at each intensity of the electrical field impressed upon the oxide film. Then the total amount of electric charges required until the oxide film makes dielectric breakdown is found by measuring the time until the oxide film makes dielectric breakdown and multiplying the time by the current density of a constant current. Thereafter, the estimated value of the service lift of the oxide film at each intensity of the electrical field impressed upon the oxide film is found by dividing the total amount of electric charges by the current density of the oxide film at each intensity of the electrical field impressed upon the oxide film.  Finally, the service life of the oxide film when the film is actually used is estimated by approximating the relation between each intensity of the electrical field impressed upon the oxide film and the estimated service lift of the oxide film based on a recurrent formula and by using the recurrent formula.

Title: Recording medium
Inventor: WATANABE SHUICHI
IPC: G03G19/00
Filed: 1987-11-25
Abstract: PURPOSE:To enable recording of a magnetic latent image by irradiation of light and control of an external magnetic field by forming network-like patterns consisting of a superconductive material on a substrate. CONSTITUTION:A recording medium 10 is produced by forming columnar projections at equal intervals on a cylindrical substrate 11 consisting of a soft magnetic material and packing network-like patterns 12 consisting of the superconductive materials therebetween. The medium 10 is rotated in an arrow direction and the entire surface is heated to the critical temp. or above by a halogen lamp 14; thereafter, a magnetic field is applied to the medium by a magnet 15. The recording medium is cooled down to the critical temp. or below while the magnetic field is held impressed thereto so that the magnetic field is captured over the entire surface of the medium 10. Recording light 16 is then projected on an arbitrary part to heat said part to the critical temp. or above; thereafter, said part is cooled down to the critical temp. or below to annihilate the magnetic field, by which the negative latent image is formed. The latent image is in succession developed by a developing device 17 and is transferred onto paper 18 for toner recording. The entire surface is heated by the halogen lamp 20 to erase the latent image.

Title: Television receiver
Inventor: HASE YUJI
IPC: H04N5/445
Filed: 1993-11-26
Abstract: PURPOSE:To provide a television receiver for preventing image signals from being superimposed and displayed even when the aspect ratio of a display device is laterally larger than that of image signals by displaying characters at certain positions within a certain range under the control of a display position control part so that no character can be omitted and extended. CONSTITUTION:The roundness is held at the center of a CRT but horizontally extended only at the left and right parts. Therefore, when displaying the image with the aspect ratio of 4:3 on the CRT with the aspect ratio of 16:9, an output control part 169 is controlled by a position control part 171, a horizontal character display position is delayed for about a 1/3 horizontal period, and a clock oscillation frequency to be generated by a clock generating part 163 is made to an frequency as about 1.5-fold high as a normal frequency by changing over a switch 166. On the other hand, the display position is enlarged until the horizontal size matches both the horizontal and vertical directions, the upper and lower parts of a picture are protruded out of the CRT and when displaying the image with the aspect ratio of 4:3, vertical dots are thinned out by controlling the control part 169 while using a character control part 172.

Title: Antenna system for searching direction of radio wave with radio wave absorbing body
Inventor: MIWA KATSUJI
IPC: G01S3/04
Filed: 1986-12-15
Abstract: PURPOSE:To prevent an input/output matching characteristic from being deteriorated over a wide frequency band by arranging a radio wave absorbing body at the rear side of the antenna. CONSTITUTION:Plural unidirectional beams are arranged by arranging unidirectional antennas whose unidirectional directivity is formed through the arrangement of a flat or recessed radio wave absorbing body 2 at the rear face of the antenna 1 in a ring or a sector shape. Since the radiation characteristic at the rear face side is erased, the action such as synthesis/ interference with the reflected wave by a reflector and the radiation characteristic of the antenna 1 itself does not exist at all. Thus, the deterioration in the input/output matching characteristic due to the frequency condition/distance between the antenna and reflecting plate is not caused.

Title: Receiver and tuning method for multi-path signal
Inventor: IWASAKI JUN
IPC: H04J13/00
Filed: 1992-10-09
Abstract: PURPOSE:To eliminate useless power consumption by latching the tuning of a multi-path signal only for a prescribed time when a signal intensity of a path is rapidly deteriorated to avoid switching control operation of the useless tuning state of the signal when the signal is recovered. CONSTITUTION:A control circuit 16 controls each of demodulation sections 141-143 to demodulate, e.g. three multi-path signals in the order of the strength of signals in response to an output from a correlation detector 15. Whether or not the intensity of the selected three multi-path signals is deteriorated to a prescribed threshold level or below within a prescribed time is detected. When the strength reaches a prescribed threshold level or below, the selection state of the three multi-path signals for a prescribed time only is latched. That is, when the signal intensity reaches the threshold level or below within a prescribed time, it is discriminated that the signal is rapidly missing due to a cause such as interruption of a path with a sender side for a short period depending on the position of a mobile body during movement at communication. Thus, the tuning state so far is latched only for a prescribed time and the recovery of the signal due to a change in the moving position is awaited.

Title: Semiconductor device
Inventor: TSUKAMOTO KENICHI
IPC: H01L21/8222
Filed: 1988-11-28
Abstract: PURPOSE:To realize a high-speed operation by a method wherein a base diffusion concentration of a bipolar element constituting a peripheral circuit of a bipolar RAM is set selectively at a high concentration with reference to a base diffusion concentration of a bipolar element inside a memory cell array. CONSTITUTION:In a semiconductor memory device 1 as a whole, a selective implantation operation of a p-conductivity-giving substance by using a mask is executed in two or more processes in order to form a base diffusion layer of a bipolar transistor. During a first selective implantation process, a mask 4 covering a memory cell array 2 wholly is used. The mask 4 used during this process is composed of a whole-face mask part 41 which covers the memory cell array 2 wholly and a selective mask part 42 which selectively exposes a base electrode extraction part inside a peripheral circuit 3. Since an ion implantation operation is blocked completely under the whole-face mask part 41, this part becomes a low-concentration base diffusion region 5; a part under the selective mask part 42 becomes a high-concentration base diffusion region 6. Thereby, it is possible to selectively set only a base region 8 of a bipolar transistor QB inside the peripheral circuit 3 at a high concentration; a high-speed operation can be realized.
