Title: Focusing device for video camera or the like
Inventor: SAKURAI HIROSHI
IPC: G02B7/08
Filed: 1988-06-03
Abstract: PURPOSE:To accomplish focusing over a wide range with good operability by moving a focusing lens with the aid of an electronic control in response to a manual operation by a focusing means and performing focusing. CONSTITUTION:A voltage VM corresponding to the position of a focusing ring 2 and a voltage VL corresponding to the position of a master lens 9 outputted from a lens position detector 11 are compared in a comparison circuit 12 and a focusing motor 15 is controlled to be driven through a motor control circuit 13 and a motor driving circuit 14. Therefore, the master lens 9 can be controlled to be stopped corresponding to the turning position of the focusing ring 2. Thus, focusing can be continuously performed from an ordinary photographing area to a macrophotographing area with the same touch as at the time of operating to turn the distance ring of a lens and focusing with a front lens, so that the device is easy to be operated.

Title: Mask for exposure
Inventor: KAWASHIMA HIDEAKI
IPC: G02B1/11
Filed: 1991-05-10
Abstract: PURPOSE:To prevent unnecessary illumination light in a glass substrate from being reflected by an end surface of the glass substrate at the time of exposure by providing reflection preventive films which prevent the illumination light in the glass substrate from being reflected at the end parts of the glass substrate. CONSTITUTION:The reflection preventive films 4 are formed on all the end surfaces 2a of the outer periphery of the glass substrate 2 of the mask 1 for exposure. The reflection preventive films 4 are formed of a light-absorbing material such as chromium oxide by, for example, vapor deposition. The reflection preventive films 4 are formed extending round to the outer peripheral part of the surface of the glass substrate 2. Consequently, when pattern exposure is performed while the mask is mounted on an exposure device, irregularly reflected illumination light R which is generated by the irregular reflection of the illumination light P in a circuit pattern 3 is absorbed by the reflection preventive films 4 formed on the end surfaces 2a of the glass substrate 2, so the irregularly reflected illumination light R is prevented from being reflected by the end surfaces 2a. Further, illumination light R' which is made incident obliquely on the glass substrate 2 is absorbed by the end surfaces 2a similarly.

Title: Protecting device for refrigeration device
Inventor: MATSUZAKI TAKASHI
IPC: F04B49/00
Filed: 1987-05-29
Abstract: PURPOSE:To prevent the excessive rise in gas temperature by restraining or removing the restriction of the upper limit value of the capacity value of a compressor in accordance with the temperature value at which the discharge gas temperature of the compressor is kept in a defined range in the vicinity of its limit for favorably maintaining the performance of a compressor lubrication oil. CONSTITUTION:At the time of a refrigerating operation, the temperature of a discharge gas is detected each time a defined time elapsed and, when the temperature still exceeds a defined range, the upper limit values of the capacities of compressors 1, 2 are restricted to the low by a capacity restricting means 52 lowering the capacities. While the lowering control of the discharge gas temperature is repeated, when the temperature is lowered below the defined range, on the other hand, since the discharge gas temperature is within a safe range with no excessive rise, this restriction is removed increasing the capacities. Thereby, excessive increase in compression ratio can be prevented while preventing excessive rise in the discharge gas temperature.

IPC: H04N5/00
Filed: 1979-10-20
Abstract: PURPOSE:To reduce the cost of reception system by separately receiving two superposed broadcast signals, differing in frequency band, after AGC amplification. CONSTITUTION:A VHF broadcast signal, received by the antenna, is amplified as it is and a UHF broadcast signal, on the other hand, is converted by the frequency converter into a signal of a frequency in the middle band, which is mixed with a pilot signal and frequency-converted signal and sent to one transmission line before reaching input terminal 11 of the line amplifier. Those input signals are distributed  to two by distributing circuit 36; one signal is amplified by AGC amplifier 14 and  the other is inputted to frequency converter 15. In converter 15, the middle-band  signal reaches mixing part 31 by way of BPF28, amplification part 29 and BPF30.  On the other hand, the signal extracted by frequency-converting signal selection  part 33 is supplied to mixing part 31 via multiplying circuit 34 and converted into a  signal of UHF, which is outputted from terminal 13 together with the output of  amplifier 14 by way of mixing circuit 37 and distributing circuit 16. This amplifying circuit provides AGC amplification on the basis of the pilot signal, so that amplifiers, when cascaded in several stages, can perform excellent reception.

Title: Optical disk device
Inventor: SAKATA SHINGO
IPC: G11B7/09
Filed: 1995-06-02
Abstract: PURPOSE: To cancel DC offset operation at high speed by detecting the DC offset of a tracking error signal by means of a DC offset detector and outputting it to an offset detecting instrument. CONSTITUTION: When an optical disk is rotated, a fine adjustment indicator 34 sends a signal FD to a driving amplifier 31 and finely move a bobbin 2 by a current complied with the signal FD. A DC offset detector 23 sends the detected signal to a converter 24 of a measuring instrument 27. Thus, the converter 24 performs A/D conversion of the signal, sends it to a microcomputer 25 as the offset data and sends cancel instructing data based on the state of the displacement of a tracking position to a D/A converter 26. The converter 26 D/A converts the instructed data and sends a cancel instructing signal to a variable resistor 28. Consequently, a tracking error signal from which the DC offset of a signal TE is automatically removed is obtained.
