Abstract: PROBLEM TO BE SOLVED: To provide a sapphire plate for increasing brightness, a sapphire plate with a polarizing plate attached thereto, and a liquid crystal projector. SOLUTION: The sapphire plate 15 is cut out of a sapphire ingot so as to make two light transmission planes through which incident light 80 is transmitted, be in parallel to each other. With respect to a C-axis 70 of the sapphire plate 15, taking the light transmission plane 20 as a standard, the incident light side and the sapphire side of the standard are assumed as the plus side and the minus side respectively. The C-axis of the sapphire plate 15 is located in an angular range 75 of <=10 deg. in the plus side and of <=10 deg. in the minus side. Taking the light transmission plane 20 on the transmitting side as the standard results in the same location of the C-axis.

Title: Train control system
Inventor: OKUYA TAMIO
IPC: B60L3/08
Filed: 2002-04-02
Abstract: <P>PROBLEM TO BE SOLVED: To accurately stop a train in front of a target stop position.  <P>SOLUTION: A train control system 10 generates a train control signal based on an upper limit speed pattern set based on P signal after receiving YP signal transmitted toward the train 12 from the ground side and a current speed of the train 12. In this system 10, a first upper limit speed pattern in which speed is gradually reduced from a predetermined speed to a predetermined terminal speed in a section C1 to be controlled whose distance is a distance L1 from a position B1 where the train arrives after a predetermined time elapses from the start of YP signal reception to the target stop position S or less is used. Consequently, when setting of the upper limit speed pattern is completed within time shorter than the predetermined time from the start of YP signal reception, train speed can be reduced to be the predetermined terminal speed or less in front of the target stop position more securely. When receiving P signal only without receiving YP signal, a device on a car performs low speed control (for example, 7.5 km/h).  <P>COPYRIGHT: (C)2004,JPO

Abstract: <P>PROBLEM TO BE SOLVED: To suppress output fluctuating due to abrupt increase in the output voltage for stable operation.  <P>SOLUTION: A switching power supply unit is provided with a current- limiting circuit, which when an inverter 3 is controlled to the stop side due to abrupt increase in output voltage, operates to suppress increase in pull-in current due to an error amplifier 9. The current-limiting circuit comprises a current limiting transistor 12 and a base bias circuit. The current-limiting transistor 12 is inserted and connected by emitter and collector, in a line which connects a power line of output voltage and the output of the error amplifier 9 via a current-limiting resistor R4 and a photocoupler light-emitting portion 11a. The base bias circuit divides a voltage, obtained by rectifying a voltage produced in a secondary winding L2 of a transformer 4 and applies the obtained voltage to the base of the current-limiting transistor 12. In response to drop in the voltage produced in the secondary winding, due to the stop-side operation of an inverter element 5, the current-limiting transistor 12 is operated in the off direction, and thereby the pull-in current of the error amplifier 9 is limited.  <P>COPYRIGHT: (C)2004,JPO
