Title: Synchronization broadcasting system
Inventor: ONO ISAO
IPC: H01Q3/01
Filed: 1994-02-10
Abstract: PURPOSE:To prevent the occurrence of a low electric field strength and defective sound quality in an equifield zone. CONSTITUTION:An oscillator 16 of a station A generates a synchronizing signal to rotate the directivity of a 1st single directivity antenna electrically at a period being a multiple of four or over a period with respect to a modulation maximum frequency, a frequency divider 17 frequency-divides the generated synchronizing signal and the resulting signal is sent to a telephone line 18. A directivity rotation section 13 rotates the directivity of the 1st single directivity antenna synchronously with the synchronizing signal generated from the oscillator 16. The period of the directivity of 1st and 2nd single directivity antennas is made identical based on the synchronizing signal on the telephone line 18 in a station B, a synchronization oscillator 26 generates a synchronizing signal used to minimize one directivity when the other directivity is maximum with respect to the directivity of the 1st and 2nd single directivity antennas and a directivity rotation section 23 rotates the directivity of the 2nd single directivity antenna synchronously with the generated synchronizing signal.

Title: Voltage regulator for ac generator
Inventor: MATSUI BUNJI
IPC: H02J7/24
Filed: 1981-02-06
Abstract: PURPOSE:To remove the defect of radio wave noise in a 3-phase AC generator driven, for example, by an internal combustion engine by providing an output voltage detecting circuit and a voltage control transistor connected to a field coil, thereby continuously controlling an exciting current. CONSTITUTION:An AC generator 2 is driven, for example, by an internal combustion engine, and is provided with a 3-phase star-connection armature coil 5 and a field coil 6. A voltage regulator 1 continuously controls a field current to regulate the voltage of the coil 5, and the charging voltage of a storage bat- tery 4 is controlled constantly. The coil 6 is initially energized by a storage battery 4, and when the generator 2 starts rotation, the voltage generated at the coil 5 is detected by a Zener diode (ZD) through a voltage divider of resistors (R) 1, 2, and when it exceeds the prescribed voltage, the ZD is conducted, and the transistor Tr 1 is interrupted. Thus, the base currents of the Tr 1, 2 are reduced, the Tr 1, 2 are controlled so that the prescribed exciting current is applied through the Tr 3 to the coil 6, and the excessive voltage is consumed between the emitter and the collector of the Tr 1.

Title: Alignment apparatus
Inventor: NISHI TAKECHIKA
IPC: G03F9/00
Filed: 1992-01-31
Abstract: PURPOSE:To detect a mark with high accuracy and at high speed by a method wherein detection ranges of two alignment systems whose detection system mutually differ are separated from each other within the field of view of an object optical system for alignment use. CONSTITUTION:A first photodetection system FIA and a second photodetection system LIA whose optical detection system with reference to reflected light from a mark is different are installed as photodetection systems. A separation means (variable magnification, diaphragm plate) which prescribes that a detection range PE2 by means of the first photodetection system FIA and detection ranges ALx, ALy by means of the second photodetection system LIA are separated from each other is installed within the angle of field of an object optical system. Thereby, when a mark pattern on an object is detected, two different alignment systems can be used alternately only by moving the object between the two detection ranges. As a result, a mark detection and a dislocation measurement can be performed at high speed.
Patent JP-S4884954-A (JP)
IPC: B07C1/04
Filed: 1972-02-17
Abstract: A flat article separating apparatus for separating overlapping articles traveling along a feeding belt is disclosed. The apparatus includes a slipping section for causing overlapping articles to slip with respect to each other. Thereafter, the articles pass through a detector which detects the presence of an article and in response to such a detection, activates a moving roller aligned with a branching section of the feeding belt to cause the belt in the area of the branching section to bend. Bending of the feeding belt in the vicinity of the branching section allows the article in the branching section to be directed to a branch path of the feeding belt. Articles whose leading edges have passed the branching section at the time the moving roller is activated, continue to move along the main path of the feeding belt.

Title: Polarized light separating and synthesizing prism for optical device
Inventor: SHIGA MASAYUKI
IPC: G02B5/04
Filed: 1987-01-27
Abstract: PURPOSE:To eliminate reflection films and to simplify construction by bringing a prism and flat plate glass into tight contact with each other while a polarized light separating film is held interposed in approximately the central part thereof and forming the prism in such a manner that the optical path within said flat plate glass satisfies total reflection conditions on the plane opposite from the tight contact part. CONSTITUTION:The three-sided prism 1 and the flat plate glass 2 are brought into tight contact with each other while the polarized light separating film 3 is held interposed in approximately the central part thereof. The optical path in the flat plate glass 2 is so set as to satisfy the total reflection conditions on the plane opposite from the tight contact part of the flat plate glass 2, by which the need for forming the reflection film on said face is eliminated and the constitution is simplified. Reflectivity is nearly 100% with both the P wave and S wave in the case of total reflection. The dependency of the loss of the synthesized light on polarization is, therefore, decreased by using such synthesizing prism. The polarized light separating and synthesizing prism which is simple in construction and acts surely is thereby obtd.

Title: Vaporization cylinder temperature safety device
Inventor: ITO MASARU
IPC: F23N5/02
Filed: 1990-01-26
Abstract: PURPOSE:To enable detection of over-heating of the cylinder and improve the safety characteristic by a method wherein a plurality of cylinders are arranged within one cylinder cover and a temperature fuse fixing plate having the temperature fuse inserted and held at a box-like part is fixed to each of the cylinders. CONSTITUTION:Since a cylinder cover 25 is integrally formed with a right cylinder 21 and a left cylinder 21, a spacing in which a cylinder expanding part 39 is exposed and a temperature fuse 43 is placed shows a high temperature. However, a fuse 43 is positioned below the cylinder cover 25 and its atmosphere is kept at a relatively low temperature and at the same time a melting cut temperature is set at a sufficiently high temperature, so that the fuse 43 is not operated under a normal operating state. However, if a heater 22 is continuously and electrically energized due to an abnormal state of a thermistor for sensing the cylinder temperature or a control device and the cylinder 21 shows an abnormal over-heating state, its temperature is transmitted to the fuse 43 by the temperature fuse fixing plate 40, the fuse 43 is operated to stop the electrical energization for the heater 22. At this time, a temperature sensing part of the fuse 43 is substantially covered by a box-like temperature fuse holding part 41, so that an atmospheric temperature at the temperature sensing part is rapidly increased and the over-heating at the cylinder 21 is positively detected.
