Title: Optical star coupler and its production
Inventor: IMOTO KATSUYUKI
IPC: G02B6/28
Filed: 1983-07-21
Abstract: PURPOSE:To decrease insertion loss and variance in distribution by heating a hollow glass tube in which an optical fiber bundle is inserted, twisting the tube to weld the hollow glass tube to the optical fiber bundle then stretching axially the welded part thereby forming a tapered part. CONSTITUTION:The light propagated rightward in one optical fiber on a left side is distributed to each optical fiber by the radiating and mixing effect in a tapered part 14 and the equally distributed light output is obtd. at the output end of each optical fiber on the right side. The light propagated rightward in the other optical fiber on the left side is similarly distributed equally to the output end of each optical fiber on the right side and is outputted. The same holds of course true of the light propagated in the optical fiber on the right side. The radiating and mixing effect in the part 14 is adjustable with the number of twisting and the stretching magnification of the part 14 or the length of the tapered part etc. For example, the degree of coupling between the optical fibers is increased if the number of twisting is increased and the variance in distribution is decreased if the stretching magnification and the length of the tapered part are increased.

Title: Light applied voltage and electric field sensor
Inventor: TADA KOUJI
IPC: G01R15/24
Filed: 1981-08-25
Abstract: PURPOSE:To eliminate the influence of resonance and expand the band of a sensor by forming parallel grooves which have finite depth in the advancing direction of light in a crystal surface crossing the advancing direction of the light at right angles. CONSTITUTION:Light incident to an optical fiber 1 is passed through a rod lens 2, a polarizer 3, and a half-wavelength plate 4 to reach a bismuth silicon oxide (BSO) element 5 formed by making parallel grooves 9 in a BSO plate of[width (w)X length (l)X depth (d)]and then dividing the whole into (n). This light changes in the state of polarization according to the level of a voltage applied from an input voltage source 7 to the BSO element 5 through an electrode, so the state of polarization is detected to detect the level of an input voltage to be detected. Consequently, while (n) is increased to decrease width T, a resonance frequency nearly depends only upon T and is increased high without reference to (l), and the transmission loss of light is reduced by decreasing groove width (t) until it causes no problem substantially.

Title: Power source equipment
Inventor: SUZUKI KOJI
IPC: H02J3/00
Filed: 1988-06-02
Abstract: PURPOSE:To produce a plurality of high voltage outputs having different output timing from a single transformer, by arranging a voltage doubler rectifier and an output control element connected to the prestage thereof at the secondary of a booster transformer. CONSTITUTION:When a transistor Q3 is controlled through a terminal P3 into non-conducting state, a capacitor C9 is charged only but voltage doubling/ rectifying operation is not carried out and thereby no DC component is outputted to a terminal J2. When the transistor Q3 is controlled into positively biased conducting state by means of a timing signal applied onto the input terminal P3, clamping operation is carried out through a clamp circuit comprising a capacitor C8, a transistor Q3 and a diode D2. Consequently, the collector voltage has maximum voltage of 0V and the output from the collector has a DC level shifted waveform. When this AC signal is rectified, DC output is produced at the anode of a diode D9.

Abstract: PURPOSE:To eliminate the need to consider the specially tight fixation of an electronic component to the surface of a printed board by forming the printed board cylindrically with its component surface in and aligning the center axis of rotation of the cylinder with the center axis of a rotary drum. CONSTITUTION:An electronic circuit is mounted on one surface of the flexible printed board 13, which is formed cylindrically with its component mounting surface in and fixed to the inner peripheral surface of the rotary drum 1. The board 13 has its axis of rotation aligned with the center axis l-m of rotation of the drum 1. Then when the drum 1 rotates at a high speed as shown by D, the electronic circuit component receives a centrifugal force in a direction F. At this time, the electronic circuit component mounted on the drum 1 is fixed on the inner peripheral surface of the drum 1, so it is pressed against the surface of the board 13 more strongly. Therefore, when the electronic circuit is assembled, the fixation need not be considered specially and the high- reliability rotary drum can be formed.
