IPC: G11B20/12
Filed: 1990-03-06
Abstract: PURPOSE:To appropriately reproduce recorded data regardless of the driving direction of a recording medium by adding a synchronizing signal after the finish of recording when plural blocks consisting of the synchronizing signal and digital data are recorded on the linear track of the recording medium. CONSTITUTION:Still picture information for retrieval from an input terminal 1 is stored in a frame memory 2. The data read out in conformity to an address signal is block-encoded by a compressing part 3, and the information is compressed. After a signal for detecting and correcting an error is added to this data by an adding part 4, the signal is modulated by a modulating part 5. Next, the synchronizing signal is added in a block unit by a synchronizing signal adding part 6, and the signal is recorded on a magnetic tape 8 by a fixed head 7. Here, when a recording finish signal is inputted from a recording finish signal input terminal 9, the signal is sent to the synchronizing signal adding part 6. At the adding part 6, the synchronizing signal 25 is added just behind the last picture information data synchronizing block 23 at the time of the recording, and the recording is finished.

Title: Probe for minute terminal probing
Inventor: MAEDA KANAKO
IPC: G01R1/067
Filed: 1993-03-15
Abstract: PURPOSE:To make electric measurement using a probe easy and protect an object to be measured by providing a recess at a tip part in contact with a portion to be measured. CONSTITUTION:A tip of a probe in contact with an object to be measured is formed in a recess and has a recess. The recess is formed so that the center of the recess is positioned at the center of the tip. It is one of features of the probe that an inner part 2 of the recess is shaped so that it can be in contact with and cover a portion 6 to be measured at the time of measuring the protruding portion 6 to increase a contact area between the portion 6 and the inner part 2. Due to this feature, stability in a contact state is better than a probe having a sharp tip, measurement is easier, and a contact face is larger, thereby reducing wearing and damage at the portion to be measured.

Title: Reflection mirror
Inventor: NITTA YUSHIRO
IPC: G02B26/10
Filed: 1994-02-25
Abstract: PURPOSE:To obtain a novel reflection mirror which affords a change in reflection direction not possible heretofore. CONSTITUTION:This reflection mirror 28 has a circular conical surface 28a of the vertex changing gradually in a circumferential direction as its reflection surface. The mirror has a step part 28c at the circular conical surface 28a as the vertex changes gradually. The reflection mirror 28 is rotated at a specified speed around the axis of the circular cone in the case of using the reflection mirror 28 as a reflection mirror of, for example, a transmission optical system of a laser radar. The reflection direction of light is oscillated and scan of transmission light is executed by a change in the vertex according to rotation when a laser beam having the optical axis parallel with the axis of the circular cone is cast to the circular conical surface 28a. In such a case, the reflection mirror rotates in a specified direction at a specified speed and, therefore, the change in the reflection direction is linear. Namely, the scan linearity of the transmission light is assured.

IPC: H01L29/68
Filed: 1987-03-10
Abstract: PURPOSE:To enhance the availability for application to various circuits by a method wherein, at a potential barrier layer, the energy level at the bottom of a conductor changes in a slope shape and the maximum value of the energy level displays either a low state or a high state in accordance with a prescribed energy level.

Title: Semiconductor device
Inventor: UENO MASAYUKI
IPC: H01L21/76
Filed: 1991-03-19
Abstract: PURPOSE:To obtain a semiconductor device having good MOS(Metal Oxide Semiconductor) transistor structure by thinly forming an end of a field oxide film to reduce impurity concentration of a channel stop layer immediately under the thin oxide film. CONSTITUTION:At an end of a field oxide film 21 surrounding an NMOS transistor region of a p-Si substrate 1, an oxide film 22 of predetermined width which is thinner than the field oxide film 21 is formed while p<+>-type channel stop layer 31 is provided immediately under the field oxide film 21. Natural diffusion of impurities in the layer 31 causes a layer 32 whose impurity concentration is lower than that of the p<+>-type channel stop layer 31 to be formed immediately under the oxide film 22. Thus difference of level in a region between the field oxide film and an element formed surface is relaxed, thereby preventing crystal defect from occurring and further preventing a wiring on the level difference from being broken.

Abstract: PROBLEM TO BE SOLVED: To improve image quality and also to reduce noise. SOLUTION: An optical box 23 is fixed to a device main body 39 by a fixing screw 40 through four leg parts 35. Long holes 35a through which the screw 40 can be inserted with a gap are formed on all parts 35, and a threaded hole 39a to which the screw 40 is screwed is formed on the main body 39.
