Title: Low-pressure vapor electric-discharge lamp
Inventor: MIKOSHIBA SHIGEO
IPC: H01J61/70
Filed: 1981-12-16
Abstract: PURPOSE:To obtain a compact single-base incandescent-lamp-type fluorescent lamp, which can be easily made and which has a high efficiency and a small luminance nonuniformity, by curving at least one of inner tubes into an almost U shape so as to make the length of the inner tube larger than that of the outer tube. CONSTITUTION:Since an electric-discharge lamp is constituted by folding a positive column four times its entire length is about one fourth of that of the conventional straight electric-discharge lamp. Therefore, the lamp can be remarkably easily handled, and has an excellent appearance. When this electric-discharge lamp is compared with the conventional electric-discharge lamp while maintaining their output luminious flux constant, since the surface area of this lamp is smaller than that of the conventional one, the luminance of this lamp becomes higher than that of the conventional one, and this lamp is used as a high luminance lamp to a larger extent. In addition, in the lamp, visible light discharge from the open end of an inner tube 103 in the axial direction, after once passing through an outer tube stem 102, returns back by being reflected by a visible-light reflecting layer provided near the stem 102. As a result, the extreme luminance nonuniformity caused on the surface of an outer tube is decreased.

Filed: 1993-08-13
Abstract: PURPOSE:To prevent pollution and to reduce operating costs by using a synthetic isoparaffin hydrocarbon cleaning agent which does not freeze at specified low temperature and does not boil at specified high temperature, as a common medium for both a cryostat and a thermostat. CONSTITUTION:A synthetic isoparaffin hydrocarbon available on the market, having a pour point of -70 deg.C or less and a boiling point of 210 to 265 deg.C, is used as a common medium at low and high temperatures. A testing device is sealed to avoid inflammation and to prevent the medium from being released into the atmosphere. In addition to sealing, the liquid phase portion of the medium may be replaced by an inert gas. The synthetic hydrocarbon has a low pour point, and therefore good flowability and low viscosity, so that little of adheres to a subject to be tested as the subject goes out of a cryostat; even if it is released into the atmosphere, its effects on the environment are almost negligible.

Title: Laser scanner
Inventor: NISHIMURA KOJI
IPC: G02B26/10
Filed: 1994-08-26
Abstract: PURPOSE: To obtain a high-resolution and low-priced laser scanner by constituting a 1st lens group movably in a direction parallel with an optical axis direction, thereby adjusting the deviation of the position of the image point of a scanning lens caused with temperature change. CONSTITUTION: Temperature is measured by a temperature sensor 13 provided near the plastic scanning lens 5, and a lens driving mechanism 14 is actuated in accordance with the temperature so as to adjust the position of the image point of the scanning lens 5. The mechanism 14 is actuated by using an exclusive controller 15. The image point position correcting mechanism is used to adjust the position of the image point in a direction perpendicular to a scanning direction, so that the deviation after correction becomes zero. In the case of correcting the deviation of the position of the image point in a main scanning direction, the same result is obtained by adjusting the position of a collimator lens 2. The temperature sensor 13 for measuring the temperature may be arranged at the optional place of a scanning optical system but it is desirable to provide it near the scanning lens 5.  It is needless to say to provide the sensor 13 inside the scanning lens 5.

IPC: H02H3/08
Filed: 1993-07-22
Abstract: PURPOSE:To surely protect an apparatus to which a current is supplied by previously obtaining an upper and a lower limit current corresponding to variation of ambient temperature, comparing next a supply current with the limit current and intercepting the supply current when an abnormal current is applied. CONSTITUTION:A current detecting means 2 detects a current supplied to an apparatus 1 to which a current is applied and outputs the detection result to a current range judging means 5. A temperature detecting means 3 is located near the apparatus 1 to detect the ambient temperature thereof and then outputs the detected temperature to a limit current range setting means 4. Here, an upper and a lower current ranges are set depending on an ambient temperature detecting signal input and it is then outputted to a current range judging means 5. In this apparatus, the supply current is compared with the limit current value. When the supply current is larger than the limit current, the supply current is judged as an abnormal current. Upon this judgement, an overcurrent protection means 6 intercepts supply of current to the apparatus 1 in order to protect the apparatus from an overcurrent.
