Title: Scanning apparatus in cassegrainian optical system
Inventor: MATSUMURA ATSUKI
IPC: G02B26/10
Filed: 1987-04-30
Abstract: PURPOSE:To improve measuring accuracy and to expand a measuring range, by providing a driving mechanism, which turns the secondary mirror of a Cassegrainian optical system at a specified period, and providing a synchronization control mechanism, which synchronizes the operation of the driving mechanism and the operation of a galvanomirror. CONSTITUTION:Light, which is emitted from a sample 1, is reflected with a main mirror 3, a secondary mirror 4 and a galvanomirror 8 of a Cassegrainian optical system. The light is inputted into a detector 14 and transduced into an electric signal corresponding to the intensity of the light. The signal is inputted into a synchronization control mechanism 18. A signal of, e.g. 50Hz, is applied to the mirror 8 from the control mechanism, and the sample 1 is scanned in the direction X. Likewise, a signal of 0.5Hz is applied to a motor 5, and the secondary mirror 4 is scanned in the direction Y. Meanwhile, a chopper 9 is operated at a frequency of 5kHz with a chopper controller 10. When, the chopper 9 is opened, the emitted light from the sample and stray light I due to the optical system and the like are detected 14. When the chopper 9 is closed, emitted light I0 from a sensor calibrating cavity 11 is detected. Therefore, the emitted light from the sample can be obtained as I-I0. The electric signal from the detector 14 is inputted into a data processor 19 and transduced into temperature.

Title: Position control method of magnetic head
Inventor: KUWAJIMA TAKAO
IPC: G11B5/56
Filed: 1980-08-07
Abstract: PURPOSE:To carry out an azimuth control simultaneously with a control of height of a magnetic head without exchanging the magnetic tape, by performing the height control of the magnetic head in the state under which the tape is actually travels. CONSTITUTION:A test tape 1 is started to vary the height of a magnetic head and the azimuth. Thus the output voltage (frequency f1) caused by the leakage flux given from a recorded part 3 varies, and a voltmeter 9 indicates the maximum value when a magnetic gap of a magnetic head 5 is set at the center of width l2 of a recorded part 2. Accordingly the height of the head 5 is controlled so that the voltmeter 9 indicates the minimum value, and thus the magnetic gap is set at the center position of a prescribed track. Furthermore the azimuth is controlled to obtain the maximum level of the output voltage of frequency f2. As a result, the azimuth can be set at the best point.

Title: Method of sealing pipe joint
Inventor: YAMADA NORIFUMI
IPC: F17D3/12
Filed: 1979-08-22
Abstract: PURPOSE: To vaporize a liquid sealant in the seal of a buried pipe such as city gas pipe with a relatively little energy, by converting the sealant into mistlike particles and then subjecting said particles to induction heating.  
     CONSTITUTION: City gas is forced from a guide pipe 19 into a sealed container 10 by means of a blower 20. In this installation, the energy required to atomize ethylene glycol as a sealant is relatively small as the purpose of a supersonic vibrator 18 is to impart its energy only to that portion of the sealant which is present in an independent chamber 17 in the sealed container 10. An inductive heater 8 is capable of heating the sealant according to the distance with which the sealant must travel through a pipe 1, depending on the fact that the finer the sealant is atomized, the more the distance is increased. The maximum distance is obtained when the sealant is thoroughly evaporated.

Abstract: PURPOSE:To decrease a required bit length by selecting each register length Ai of registers of the i-stage having a prescribed relation decreased sequentially in the increasing direction of a track number in response to a bit number M and a track number T of a data word, sending data other than the MSB of each register to the lower stage and recording the MSB on a tape. CONSTITUTION:The bit length Ai of registers 5-1-5-10 being the same number as T=10 is decided to satisfy a prescribed relation in response to the minimum values of integers l, n satisfying the relation of integer K=M/l=T/n>1, where ZNT(X) is an integer not exceeding X, and the minimum values of l, n in case of T=M=10 are '1'. Thus, the relation of A1=M, A2=9...A10=1 is obtained, and the integer l is a register bit reduction between tracks. The data other than the MSB latched in each register is fed sequentially to the lower stage from the register 5-1, and the MSB of each stage is fed to a tape track corresponding sequentially selectively and recorded. Thus, the required bit length is reduced sequentially to attain cost-down.
