Title: Shortening method of focal length of zoom lens
Inventor: IKEMORI KEIJI
IPC: G02B15/173
Filed: 1984-10-11
Abstract: PURPOSE:To obtain a focal length shorter than that at a wide-angle end by moving the 1st and the 2nd lens groups in the optical-axis direction, and moving the 4th lens group in the optical-axis direction at a different speed. CONSTITUTION:The 1st, the 3rd, and the 4th lens groups having positive refracting power and the 2nd lens group having negative refracting power are arranged successively from the object side. When the lens is zoomed to the normal telephoto side, a group L1 is moved to the object side Z1, a group L2 is moved to an image side Z2, and a group L3 is put in reciprocal motion Z3 to the image side while a group L4 is fixed. When the focal length is shortened, the groups L1 and L2 provide negative refracting power as one body and move from the wide-angle end of a variable focal length range to the object side as shown by A1, the group L3 is fixed, and the group L4 moves to the image side as shown by A2. Therefore, high performance is maintained continuously in a zoom range and needs to be obtained only at the end terminal of a focal length expansion range, so the power of each group needs not be increased and aberration compensation is facilitated, thereby maintaining the high performance.

Title: Manufacture of compound semiconductor device
Inventor: KODAMA KUNIHIKO
IPC: H01L29/812
Filed: 1981-12-26
Abstract: PURPOSE:To improve the output characteristic and noise of a compound semiconductor device by covering the surface of compound semiconductor with an insulating film of Si compound, implanting H ions in the film and heat treating in H2 stream. CONSTITUTION:An n type GaAs active layer 3, source and drain electrodes 4 of Au-Ge, and Al gate electrode 5 are formed on the basis of a conventional method, and a CVD SiOx 1 is covered. Then, H ions of approx. 10<12>/cm<3> are implanted to the film 1, and are treated at 400 deg.C in H stream for approx. 20min. The H reacts with As by this treatment, thereby becoming AsH3, which volatilizes. Thus, excess Si and H performs an atomic bond, thereby eliminating dangling bond and removing the adverse influence of mutual diffusion. Then, a window is opened at the film 1, and an electrode is attached. According to this method, electric characteristics can be improved even in other III-V Group or II-VI Group compound semiconductor device. Further, instead of SiOx, SixNy may be employed.

Abstract: PURPOSE:To obtain a D/A converter at low cost, with high resolution and high accuracy by providing a switching means switching a voltage connected to other terminal of an offset level control resistor to a lower limit voltage or an upper limit voltage. CONSTITUTION:A switching means 22 switches a voltage connected to an offset level control resistor 21 from a lower limit voltage AVSS to an upper limit voltage AVDD based on the changeover of a voltage applied to a weight resistor 3 of an R-2R ladder resistor circuit 1 from the lower limit voltage AVDD to the upper limit voltage AVDD corresponding to a most significant bit d7 of, e.g. a digital input signal. Thus, even such as the variance of a resistive element being a component of a resistance circuit 1 exists, the increasing amount in the analog voltage at the time of switching from the lower limit voltage AVSS to the upper limit voltage AVDD of the voltage applied to a weight resistor 3 is not negative. Thus, the D/A converter at a low cost, with high resolution and high accuracy is obtained without requiring a highly accurate resistive element.

Filed: 1981-12-26
Abstract: PURPOSE:To improve the performance of automatic stopping mechanism of a tape recorder, by simplifying a tape termination detecting mechanism and securing an assured working of even at the time of pause. CONSTITUTION:When a recording or playback controller is operated, an idler 16 is pressed to a flywheel FW19 as well as to a drum 21 of a reel drive disk 20. The turning force of the FW16 is transmitted to the disk 20 via the idler 16 and the drum 21.
