Abstract: PURPOSE:To make it possible to write and read data stably by forming focusing plate springs which support a holding part of an objective lens in an approximately H shape by using two strip-shaped parts and a bridging part for linking the strip- shaped parts. CONSTITUTION:This apparatus is composed of an objective lens 1, a holding part 2 for the objective lens 2, a pair of upper and lower plate springs 7a and 7b for rotatably supporting the holding part 2 in the direction of an optical axis, a relay member 4 for fixing one end of each plate spring and a tracking plate spring 5 one end of which is fixed to the relay member 4 and the other end of which is fixed to a base 6. The focusing plate springs 7a and 7b have the plate surfaces crossing the optical axis at right angles. Both springs are arranged in parallel to each other. One end of a strip-shaped part 7c is fixed to the holding part 2, and the other end is fixed to the relay member 4.

Title: Radio receiver
Inventor: YOSHITAKE TSUTOMU
IPC: H01L39/04
Filed: 1999-11-09
Abstract: PROBLEM TO BE SOLVED: To provide a mount method of a radio receiver by which a cooling efficiency of a reception band pass filter and a reception low noise amplifier on a cooling stage can be improved. SOLUTION: A 1st reception band pass filter 2 is placed on a cooling stage 6. The cooling stage 6 and the 1st reception band pass filter 2 are cooled to a sufficiently low temperature such as about 70K or below. A reception low noise amplifier 3 is placed on a 2nd cooling stage 11. The 2nd cooling stage 11 is kept to a temperature higher than that of the cooling stage 6, on which the 1st reception band pass filter 2 is placed, such as about 10K. The thermal noise of the reception low noise amplifier 3 is almost unchanged between 100K and a lower temperature such as 70K. Thus, in order to realize a low noise characteristic for the high sensitivity wireless receiver, cooling at about 100K is enough for the reception low noise amplifier 3 and then the cooling load can be reduced accordingly.

Title: Voltage sensing circuit
Inventor: HIRANO HIROSHIGE
IPC: G05F3/24
Filed: 1994-12-22
Abstract: PURPOSE: To suppress the peak of consumption current in a temporarily short- circuited state and reduce the consumption of current of a whole circuit by connecting a NOT circuit to a third node connected to a fourth resistor. CONSTITUTION: A source, a gate and a drain of a P-channel type MOS transistor Qp12 are respectively connected to power supply voltage VDD and nodes N11, 13, while a source of a P-channel type MOS transistor Qp13 constituting a NOT circuit is connected to the node N13. Since potential of a node N12 being an input of a circuit 11 comprising the transistor Qp13 and an N-channel type MOS transistor Qn12 is intermediate voltage between ground voltage Vss and the node 13 when the voltage VDD is approximately 3.5 V, both transistors Qp13, Qn12 are turned on to be in a temporarily short-circuited state, thereby maximizing a current value. Since the transistor Qp12 suppresses the current value, however, consumption current In10 of the transistor Qn12 is a peak of 0.05μA. In addition, when the voltage VDD is not approximately 3.5V, current In10 is 0.1μA or less.

Title: Formation of protective coat in feedwater line for boiler
Inventor: KAWACHI ATSUSHI
IPC: F22B37/00
Filed: 1994-12-22
Abstract: PURPOSE: To lessen the corrosion of the inner surface of a feedwater pipe for a boiler. CONSTITUTION: Concentrated oxygen gas is supplied to the boiler water which flows through a feedwater pipe 16 provided between a boiler 3 and a condenser 13. The oxygen gas dissolves in the boiler water, which then becomes oxygenated water. By contact of the oxygenated water with the inner surface of the feedwater pipe 16 a protective coat of iron oxide for preventing corrosion is formed on the inner surface. The oxygen gas contains corrosive gases, such as carbon monoxide and carbon dioxide, as components, but since their concentrations are extremely low, the inner surface of the feedwater pipe 16 becomes difficult of corrosion before formation of the protective coat.
