Title: Air-cooled condenser
Inventor: MATSUO ATSUJI
IPC: F28B1/06
Filed: 1997-07-04
Abstract: PROBLEM TO BE SOLVED: To enhance the condensation performance of an air-cooled condenser for condensing steam by cooling with the air. SOLUTION: Steam from an inlet pipe 1 passes through an inlet chamber 2 and flows into a heating tube 3 arranged vertically. The condensate flows from an outlet chamber 4 into an outlet pipe 5 and uncondensed gas flows out from a bent pipe 6. The air flows in from below through a fan 7 being driven by a motor 8 and cools down the heating tubes 3 sequentially from the lower stage toward the upper stage. Consequently, the steam in the heating tube 3 is condensed and liquefied on the outlet side before flowing out from an outlet pipe 6. Each heating tube 3 is provided with an orifice 11 except the lowermost stage and the orifice 11 is made narrower toward the upper stage. Since the temperature difference between the steam and the air decreases toward the upper stage, the condensation capacity is decreased toward the upper stage.  Heat transmission area of the heating tube 3 is utilized effectively by restricting the quantity of steam toward the upper stage so that condensation just completes on the outlet side of each heating tube 3.

Title: Developing device and development method as well as production of master disk
Inventor: KOYAMA EIJI
IPC: H01L21/027
Filed: 1999-06-25
Abstract: PROBLEM TO BE SOLVED: To provide a developing device which is capable of preventing the occurrence of an uneven development and surely removing the exposed parts exposed with fine patterns, and a process for development. SOLUTION: The developing device has an ultrasonic vibrator 3 supported by a supporting plate 7 above a master disk 1. The developer is filled between the supporting plate 7 and the master disk 1 and the master disk 1 is rotated by a turn table 4 while ultrasonic waves are generated by the ultrasonic vibrator 3. As a result, the ultrasonic waves are propagated to the developer 14 and the penetration of the developer 14 to photoresist is made uniform. The ultrasonic vibrator 3 is moved relatively with the master disk 1 by rotating the master disk 1, thereby, the uniform propagation of the ultrasonic waves to the developer 14 formed over the entire part of the master disk is made possible. As a result, the occurrence of the uneven development is prevented and the formation of the desired patterns to the photoresist is made possible.

Title: Reproducing device for optical information signal
Inventor: TAJIMA OSAMU
IPC: G11B7/12
Filed: 1981-11-10
Abstract: PURPOSE:To control even the light emission part temperature and oscillation wavelength of a semiconductor laser by using an interference filter and a photodetecting device used as a focus error detecting means even for the detection of variation in the oscillation wavelength of the semiconductor laser. CONSTITUTION:Output signals from photodetecting elements 9Ta and 9Tb of a photodetecting device 9T are summed up by an adder 16, whose output signal varies according to variation in the oscillation wavelength of a laser 1 as the quantity of trasmitted light of an interference filter 8 varies. On the other hand, output signals from photodetecting elements 9Ra and 9Rb are summed up by an adder 15, whose output decreases according to an increase in the quantity of transmitted light of the interference filter 8. Therefore, the output of a subtracter 13 which subtracts the output of the adder 15 from that of the adder 16 shows the direction and value of the increase or decrease in the oscillation wavelength of the laser 1. This output is supplied through an amplifier 19 to a heating and cooling element 20 to control the temperature of the laser 1, and then the light emission part temperature and oscillation wavelength of the laser 1 are controlled automatically to specified values.

Abstract: PURPOSE:To realize both the reading and writing operations for a magnetic disk device and at the same time to cope with an alteration of the format on a medium, by varying the control information of a first-in/first-out type buffer register with a microprogram. CONSTITUTION:When a data is read out of a magnetic disk device 3, a microprogram loads the prescribed information to a first-in/first-out type buffer register controller FIFO207 and then clears a byte counter 209 when an index mark is sent from the device 3. The the output of the FIFO207 is set to a gap counter 208. Then the FIF 207 shifts by a word after setting the count value to the counter 208. The counter 208 produces a carry when finising its counting. Then the output of the FIFO207 is set to the counter 208 with the carry with which the counting is through, and at the same time the output of the FIFO207 is set to an FF211 to open a read gate to the device 3.
