IPC: E21B7/20
Filed: 1993-10-07
Abstract: PURPOSE:To prevent a pit wall from collapsing as excavation proceeds even if an excavated pit is large in diameter, and thereby materialize both the quick maintenance of a pit condition and the security of its stability. CONSTITUTION:A vertical strip folding hinge section 3 directed inward is formed in the longer direction of a spiral corrugate pipe 2 in such a way that it can be contracted in diameter. As excavation proceeds, let the spiral corrugate pipe 2 in a diameter contracted condition pass through the inside of an existing spiral corrugate pipe which is expanded in diameter so as to be pressed on a pit wall 6a, and it is then lowered down. Subsequently, the spiral corrugate pipe lowered down is then expanded in diameter so as to be connected to the lower end of the existing spiral corrugate pipe 2.

Title: Method and device for generating pulse signal
Inventor: GOTO AKIHIRO
IPC: H01L43/00
Filed: 1997-09-17
Abstract: PROBLEM TO BE SOLVED: To achieve high resolution by forming a magnetic circuit via an object to be detected at a magnetic element for applying fixed magnetic field, by causing a great Barkhausen jump by changing the magnetic field due to the behavior of the object to be detected, and by taking out a pulse signal. SOLUTION: Flux from a permanent magnet 41 for constituting a magnetic circuit formation member 4 passes through a detection part 4A. When a tooth 10 of the gear of the object to be detected reaches the detection part 4A, the strength of a magnetic field is changed due to the recesses and projections. When the tooth 10 of the gear approaches the detection part 4, the flux is concentrated to the detection part 4A, an external magnetic field to a magnetic element 1 is reduced, and the soft layer of the magnetic element 1 is magnetized oppositely to a hard layer for setting.  On the other hand, when the tooth 10 of the gear leaves the detection part 4, the flux is not concentrated, the external magnetic field to the magnetic element 1 is increased, the magnetic field is reversed, the magnetic field in the same direction as the hard layer is added, and a great Barkhausen jump is generated when critical strength is exceeded, thus generating a pulse voltage in a detection coil 2 and achieving detection regardless of the speed of the tooth 10 of the gear.

Title: Color original reader
Inventor: SHOJI TSUTOMU
IPC: H04N1/04
Filed: 1991-09-30
Abstract: PURPOSE:To reduce a required memory capacity by varying a valid picture range in the main scanning direction corresponding to the magnification and inhibiting the write of picture data at the outside of the valid picture range to a delay memory. CONSTITUTION:A 3-line CCD 1 is arranged in the subscanning direction in the order of R, G, B and an inter-line correction circuit 25 is used to match the position of preceding R, G signals with a succeeding B signal. The circuit 25 is made up of delay memories 32 whose number is equal to number of lines equivalent to the interval of each of line image sensors. A timing generating circuit 27 generates a timing designating a range in the main scanning direction in matching with the main scanning magnification at the magnification. Simultaneously, write/read of the memory 32 is implemented in matching with the timing and the write is inhibited at the outside of the valid picture range. Since the relation of required delay memory number=inter-line correction numberXvalid power supply number is in existence, the valid picture signal is varied in response to the magnification to control a write/read signal of the memory 32 thereby suppressing the increase in delay memory number attended with the magnification.

Title: Pyroelectric temperature sensor
Inventor: HASHIMOTO KAORU
IPC: G03G15/20
Filed: 1985-11-11
Abstract: PURPOSE:To prevent the output of an amplifier from being saturated and to expand a temperature measurement range by varying the chopping time of heat rays incident on a pyroelectric element. CONSTITUTION:When the output of the amplifier 4 is saturated, a level detecting means 5 detects that and generates an intermittence time switching signal. Consequently, a new intermittence time is set and the time when heat rays are incident on the pyroelectric element 3 is shortened. Consequently, a sampling time is varied eventually. The output waveform of the pyroelectric element 3 is therefore cut before reaching its original peak value and its crest value decreases. Namely, the level of an input signal to the amplifier 4 drops and its output is prevented from being saturated.

Filed: 1992-09-22
Abstract: PURPOSE:To provide the equalizer circuit in which a flat phase change characteristic is realized over a wide frequency band so as to decrease a swell of a group delay characteristic thereby suppressing the deterioration in an error rate or the like. CONSTITUTION:After a reproduction signal from a head 1 is amplified by an amplifier 2, the amplified signal is inputted to an equalizer 11 having a transfer characteristic of (omega1+s)<2>/s. The equalizer 11 has an integration characteristic in a lower frequency band then the omega1 and a differentiation characteristic in a higher frequency band than the omega1. An output signal of the equalizer 11 is inputted to a first order phase equalizer 12 whose transfer characteristic is (omega2-s)/(omega2+s) and a variable resistor (RV1) 8 is used to adjust the phase. An output signal of the phase equalizer 12 is inputted to a cosine equalizer 9, a variable resistor (RV2) 5 is used to adjust the gain and an equalized output SEQ is outputted. When the frequency phase characteristic is adjusted, the flat phase change characteristic is realized over a wide frequency band, then undulation of the frequency group delay characteristic is made less and deterioration in an error rate or the like is suppressed.
