IPC: G21F9/30
Filed: 1979-07-04
Abstract: PURPOSE: To prevent occurrence of cracks in cutter, by pushing rotary cutters onto the outer surface of a cylindrical member to be cut which is turned around a shaft, in the manner that these rotary cutters are turned together with the cylindrical member, and urging the cutters into the outer surface of cylindrical member while producing plastic deformation in the form of a V-shaped groove in the outer surface of cylindrical member.  
     CONSTITUTION: Included angles of rotary cutters 26 and 27 are set at 35 degress and 50 degrees, respectively, and clearance angles of these rotary cutters 26, 27 are both set at 50 degrees. A plurality of such rotary cutters 26, 27 are disposed around a turning cylindrical member 10 in the manner that they are turned together with the cylindrical member 10. Here, the rotary cutters 26 are used only for cutting the cylindrical member 10 whereas the rotary cutter 27 are used only for  enlarching the cut formed in the member 10 by the rotary cutters 26. By use of such  rotary cutters 26, 27, cylindrical member 10 is cut while producing a V-shaped  groove in the outer surface thereof. By employing such a method, it is enabled to  prevent occurrence of cracks in cutters due to cutting resistance acted in forming a V-shaped groove in the member 10.

Title: Signal receiving system in sound in-band signal device
Inventor: ASANO SHIZUO
IPC: H04Q1/446
Filed: 1984-05-01
Abstract: PURPOSE:To miniaturize a device and to improve cost performance by utilizing a level detection circuit for deciding definitely the difference between levels of a sound signal and a dial signal. CONSTITUTION:A specific signal corresponding to a dial signal is equalized in terms of amplitude by an equalizer 1, and inputted to a level detection circuit 12 through a signal filter 2 and a rectifier 3, thereby detecting the specific signal. The sound signal is obtained by synthesizing various types of single frequencies, and a level of each single frequency takes a smaller value. The dial signal is a single frequency and its level is substantially higher, compared with that of the sound signal. Paying attention to this fact, the circuit 12 compares a dial signal (a) with the sound signal level in the vicinity of the frequency of the dial signal. When it is larger than a level decision point of (a+b)/2, it is decided to be the dial signal. However, when it is lower, it is decided to be the sound signal; therefore a secure decision can be possible.

Title: Liquefaction preventive pile and sheet-pile
Inventor: IIDA TAKESHI
IPC: E02D5/04
Filed: 1990-03-30
Abstract: PURPOSE:To prevent the peripheral foundation of a pile or sheet-pile from being liquefied by proving a plurality of holes on a liquefaction preventive pipe, a filter for preventing the invasion of soil in each hole, or a plurality of drain members on the outer surface of a pile main body or a sheet-pile main body. CONSTITUTION:A liquefaction preventive pile 1 (1') and a liquefaction preventive sheet-pile 2 are piled in a sandy foundation 21 through a soften foundation or viscous soil foundation 20. Prior to the piling work, in order to prevent holes 3, 4 and a soil invasion filter 5 from being packed with viscous soil or the like, the holes 3, 4 having the filter 5 are filled with such a material as to be soluble after the elapse of the predetermined time. Thus, the pile 1 or sheet-pile 2 is piled. Subsequently, after the predetermined time, the filling material 10 is dissolved in underground water to thereby achieve the drain function, as a result of which the holes and filters are prevented from being packed with viscous soil or the like. Therefore, it is possible to prevent the side flow and slippage of the foundation and also prevent the liquefaction due to the vibrational outer force such as earthquake and wave.

Title: Gas laser oscillator device
Inventor: MASUDA KOICHI
IPC: H01S3/036
Filed: 1989-04-05
Abstract: PURPOSE:To reduce the uptake of lasing gas by controlling an increase or a decrease of gas supply by gas supply adjusting means on the basis of the amount of discharge power current supplied to an oscillator body or the amount of a discharge current. CONSTITUTION:Greater discharge power is supplied from a power supply device 17 to an oscillator body 11 when a laser output is set greater, whereby deterioration of laser gas in the oscillator body 11 is promoted. Thereupon, a control device 15 controls the device such that gas supply by gas supply adjusting means 18 is increased depending on the discharge power. Accordingly, the laser gas in the oscillator body 11 is exchanged rapidly to prevent the laser output from being lowered. Alternatively, when the laser output is set smaller, the discharge power from the power supply device 17 to the oscillator body 11 is reduced and hence deterioration of the laser gas is also suppressed. Therefore, the control means 15 adjusts the device such that the gas supply by the gas supply adjusting means 18 is decreased. Hereby, the consumption of the laser gas is reduced.

Filed: 1995-04-12
Abstract: PURPOSE: To realize stable focus servo pull-in operation by obtaining always stable focus servo loop performance independently of the amplitude of a focus error signal at the time of focus servo pull-in. CONSTITUTION: Before the focus servo pull-in operation, an objective lens 4 is moved back and forth in the focus direction once or plural times. In this back and forth moving process, the amplitude of the focus error signal FE is measured with an amplitude measuring circuit 1b of FE signal, and a focus servo gain is measured corresponding to the amplitude of the FE signal. Thus, the always stable focus servo setting operation is obtained even when the amplitude of FE signal is extremely large or small due to the variance in the signal performance in an optical pickup or the variance in the reflectance of an optical disk.
