Title: Video tape recorder control device
Inventor: TAKAHASHI ISAO
IPC: G11B15/467
Filed: 1987-08-13
Abstract: PURPOSE:To control the phase of a capstan in accordance with the phase difference between a subcontrol signal and a frequency reference signal by providing a subcontrol track on a tape and writing the subcontrol signal having a higher frequency than a control signal. CONSTITUTION:The subcontrol track 21 for recording the subcontrol signal is provided in the recording format of a magnetic tape Ta. This subcontrol track 2 is recorded in between two audio tracks 6, and is recorded with a higher frequency than a frequency band of an audio signal. Furthermore, it is recorded at a different azimuth against the adjacent audio track 6. At the time of reproducing, this subcontrol signal is reproduced, and then the phase difference between this and the reference signal is detected. By this method, a speed control for a capstan motor is carried out, while a further fine tape traveling control can be performed in the reproducing operation in one field.

Title: Charged beam image drawing equipment
Inventor: YOSHITAKE HIDESUKE
IPC: H01J37/20
Filed: 1997-07-29
Abstract: PROBLEM TO BE SOLVED: To improve precision of image drawing, by uniformly irradiating the whole surface of a specified region of a specimen, with a light of a Z sensor using a light for specimen surface position detection. SOLUTION: In this image drawing method, after a specimen 21 is set on a stage 31, it is scanned in order to measure the height as far as the specimen surface in the peripheral part of a pattern region 51 or in the end portion of the specimen 21, and the position of the specimen 21 is moved. In a location other than the pattern region 51, the illumination light of a Z sensor is turned on, and the height as far as the specimen 21 surface is measured. While the Z sensor illumination light is ON, the stage 31 is so driven that the whole surface of the specimen 21 is scanned by the locus of a spot 61 of the Z sensor illumination light. When the locus reaches the drawing start point 53 of the first frame of the pattern region 51, image drawing is started by turning on electron beam irradiation, in order to draw a circuit pattern.  In the state that the Z sensor is turned on, image drawing is performed also in the pattern region 51, successively to the peripheral region.

Title: Vapor growth device and vapor growth
Inventor: TANAKA HITOSHI
IPC: H01L21/205
Filed: 1989-08-04
Abstract: PURPOSE:To put a vapor growth device to practical use so that it makes the distribution of film thickness uniform by providing a heat resisting plate between a susceptor and a ceiling and making its height variable in such a way that the plate makes its height high at the inflow side of a material gas and its height becomes lower as it gets near the gas outflow side and regulating the flow rate of the material gas to the substrate surface to be treated. CONSTITUTION:Two pieces of bellows 11 are provided at the upper part of a reaction tube 1 and the reaction tube 1 is made up so that its tube suspends a heat resisting plate 13 equipped with hooks 12, besides, the extensibility of the bellows regulates inclination angles of the plate 13. Such a configuration enables this device to control easily the flow rate of the reaction gas and eliminates the need for replacing a susceptor 2 in the same way as that found in the conventional devices even in the case where continuous film growths, e.g. a hetero epitaxial growth are performed. The film growths which are uniform in their film thickness distribution are thus performed by changing gradients of the heat resisting plate 13.

Title: Self-excited switching power supply
Inventor: KOJIMA HIDEKI
IPC: H02M3/338
Filed: 1994-08-05
Abstract: PURPOSE:To obtain a high output power supply at low cost while suppressing the lowering of efficiency due to a ringing suppressing means by suppressing the peak of surge voltage caused by ringing regardless of the winding structure of a transformer. CONSTITUTION:The feedback winding NF of a transformer T is connected, at one end on the gate side of a switching transistor Q1, with the cathode of a diode D2 having anode connected with the other end of the feedback winding NF through a parallel circuit of a capacitor C3 and a resistor R3. This circuitry prevents abnormal self-excitation and ensures a high output capacity. Furthermore, lowering of efficiency is suppressed because a snubber circuit, comprising the diode D2, the capacitor C3, and the resistor R3, is provided for the feedback winding NF which processes only low power. This circuitry increases the degree of freedom in the winding method of transformer while reducing the cost.
