Title: Jitters detection circuit for optical disk device
Inventor: SHIMOJIMA AKIRA
IPC: G11B20/14
Filed: 1995-02-22
Abstract: PURPOSE:To detect jitters at the time of recording/reproducing even when a kind of an optical disk is different by obtaining a time width of an NT (N: integer 3<=N<=11) pulse signal in which the jitters occur by the number of clock pulse signals counted by a count circuit. CONSTITUTION:A 3T length measuring circuit 2 inputs a system clock pulse signal CLK and a regenerative EFM signal, and counts the number of the signals CLK incorporated in the time width of the regenerative EFM signal, and outputs the signal corresponding to a detection range. On the other hand, the count circuit 3 is constituted of four count blocks 30a-30d, and the number of 3T pulse signals respectively incorporated in first to fourth detection ranges are counted respectively. By such a constitution, since how many 3T pulses are incorporated in respective four detection ranges is obtained easily, by operation processing the serial data outputted from the count block 30a, the occurrence condition of the jitters is obtained easily.

Title: Needle thread-controlling device for sewing machine
Inventor: SEKI MASAYUKI
IPC: D05B69/20
Filed: 1989-02-13
Abstract: PURPOSE:To make it possible to automatically balance the stitch and tense the thread in any movement of feeding by providing a timing-deciding device by which work- feeding is partially done while a needle thread is released by both of contact members after an output from a phase-detecting device for an arm shaft and a stitch-pattern data from a storing device are received, and the larger the feeding movement of work is, the later the starting timing of a period of the needle thread being released is made. CONSTITUTION:A timing-deciding device is operated by a phase signal from a phase- detecting device and a stitch-pattern data from a storing device, and work-feeding is partially done while a needle thread is released by a pair of contact members. The starting timing of a period of the needle thread being released is also so decided that the larger the feeding movement of work is, the later the time of the needle thread being released is made. Since a controlling device controls a contact member- driving device so that the needle thread can be released by its starting timing, the needle thread is released after both of the contact members are relatively shifted from an access position to a separate position. As a result of it, the needle thread is fully tightened by being operated together with the feeding movement while restricted, and is fed to a thread take-up lever from a thread-spooling piece, which is necessary for forming the next stitch.

Title: Temperature controller
Inventor: SHIOHAMA EIJI
IPC: G05D23/19
Filed: 1990-02-15
Abstract: PURPOSE:To keep a second heating element within an allowable operation temperature range and to bring a first heating element to the operation temperature in a short time by making the thermal time constant of the first heating element larger than that of the second heating element. CONSTITUTION:A cooling fan 15 is periodically turned on for a certain time and is interruptedly operated. Consequently, the temperature of a switch element 22 mounted on a circuit board rises during turning-off of the cooling fan 15 and falls during turning-on of the cooling fan 15. Since the thermal time constant of the switch element 22 is small, the temperature quickly falls when the cooling fan 15 is turned on. Since a display element 11 has a thermal time constant considerably larger than that of the switch element 22, the display element arrives at the upper limit of the set range of the operation temperature in the time approximately equal to the time which is spent in arrival with the cooling fan 15 turned off. Thus, the second heating element is kept within the allowable operation temperature range and the first heating element arrives at the operation temperature in a short time.

Title: Steam cooled gas turbine
Inventor: AOKI SUNAO
IPC: F01D11/02
Filed: 1998-02-17
Abstract: PROBLEM TO BE SOLVED: To enable efficient recovery of steam that leaks from a seal on a supply side by supplying steam from the center area of the rotating shaft such that the steam is recovered from the outside, and furthermore, to also enable the recovery of heat extension. SOLUTION: The steam 30 on the supply side is supplied to a cavity 27 from within a cylinder 10. The steam 30 then passes through a groove provided in the coupling surface 26 of the turbine main shaft 1 of a four-step disc 24, and then passes from a supply duct 15 through supply ducts 11a, 12a so as to be supplied to rotor blades 11, 12. The steam 31 on the recovery side after cooling passes from the recovery ducts 11a, 12b through a recovery duct 16, a radial recovery duct 17, and an axial recovery duct 18 where it is recovered from a hole. In the turbine main shaft 1, the coupling surface 26 side becomes cool and the opposite side becomes hot. As a result, the abutted surface 26 closes due to the thermal stress, thereby preventing leakage of the steam 30 on the supply side.  Also, the turbine main shaft 1 is sealed by a static side seal 4a and a rotary side seal 4b such that steam which leaks from the seal is efficiently recovered. Axial movement is possible by a piston ring of the cylinder 10 and a centering piece 6 such that the thermal stress is absorbed.
