Title: Electron beam drawing device
Inventor: KURODA KATSUHIRO
IPC: H01J37/305
Filed: 1977-11-14
Abstract: PURPOSE: To ensure the easy-to-adjust exposure with high speed and high accuracy by irradiating the electron beam over the entire surface of the mask containing apertures of different shapes and sizes and then securing the image formation on the irradiation surface through selection of only one transmission beam.  
     CONSTITUTION: An image formation is given through lens 3 to the electron beam which has passed through aperture 14 in accordance with the shape of the aperture, and selecting aperture 15 is distributed on the image-formation surface. As the image of crossover 1 is at the center of lens 3, the arrangement is given so that the image position may be the deflecting center of the selecting deflection system. As a result, the electron beam does not get out of the optical axis whichever aperture 14 may be chosen on mask 7 through action of deflection system 22. and thus the aperture image is formed on mask 7 on selecting aperture 17 after passing through the center of lens 3. Aperture 14 outside the optical axis has the image formation out of the axis. In this way, system 22 carries out correction for the aperture selection and the axis shift, and furthermore the irradiation switching is possible via system 22 and aperture 15.

Title: Detecting method in contact of seed crystal to melt in crucible
Inventor: ITOU TOSHIHARU
IPC: C30B15/20
Filed: 1978-11-06
Abstract: PURPOSE: To control the lowering speed of a seed crystal and automatically attach the crystal to a melt in a crusible by detecting changes in apparent wt. of the crystal, e.g. an increase due to tension produced between the crystal and the melt at the time of contact and a decrease at the time of separation.  
     CONSTITUTION: Holder 4 fitted with seed crystal 3 is set over raw material melt 2 in crucible 1, and wt. measuring unit 5 is attached onto holder 4. Wt. signals of crystal 3 and holder 4 are denied with initial wt. denying unit 6, and a signal from unit 5 is set to ±0. In order to attach crystal 3 to melt 2, fast feed controller 10 for vertically moving crystal 3 is driven to lower crystal 3. When crystal 3 contacts to melt 2, ⊕ signal of an increase in wt. due to tension between them is generated in unit 5. This signal is converted into a pulse signal with differentiator 7, amplified 8, and shaped with waveform shaping circuit 9. According to this output signal, controller 10 is controlled to stop fast feed motor 11.

IPC: H02P27/02
Filed: 1977-11-11
Abstract: PURPOSE: To perform pulse driving through a single switch, by connecting a switching circuit in parallel with a series circuit composed of the inductor motor and a capacitor and controlling the switching circuit through a control circuit having a transistor.  
     CONSTITUTION: The switching circuit S, which is controlled through the control circuit CD, is connected in parallel with the series circuit composed of the inductor motor M and the capacitor C. A DC power source E is coupled to the switching circuit S through a diode D. The capacitor C is charged through the motor M by closing a switch SW. The control circuit CD detects the turn-off of the power source E in terms of the turn-off of the switch SW to trigger the gate of the switching circuit S to discharge the capacitor through the switching circuit S. Therefore, electrical current is caused by the turn-on/off of the switch SW to flow through the motor M back and forth alternately. As a result, the motor is rotated by each Hz, namely, the motor is pulse-driven.

IPC: G01M15/00
Filed: 1994-06-20
Abstract: PURPOSE:To improve knocking decision precision by deciding whether knocking of an internal combustion engine occurs according to a strength correction value corrected by a strength correction means and a back gland level set by a back gland level setting means. CONSTITUTION:Knocking occurring to an engine body 1 is converted into an electric signal for delivery. An electric signal from a knock sensor 2 is pre- processed and the pre-processed signal is ADD-converted to analyze a frequency and detect a knock frequency. A vibration level at each knock frequency is determined and a back round level is determined. A knock decision index is then determined and a total sum of a square of standardized vibration level normalized at each knock frequency is obtained to decide a knock. Namely, a value of a knock decision index is compared with a threshold ((an average back round level)X(a set value)) to decide the presence of a knock. A set value forms a value set at intervals of the number of revolutions and precision of knocking decision can be improved.

The region including the radius 17 is rolled for work-hardening with a rotating device. Threads 25 are successively formed in the end part 19 after the hardening operation. Thereupon, since the groove 15 exists, incomplete threads are not formed exceeding the length of the minimum limit i.e., 180 deg.. Thus, the collar 30 and the pin 45 are combined vary compactly in the minimum length with satisfactory strength and adaptability.
