Filed: 1999-05-17
Abstract: PROBLEM TO BE SOLVED: To obtain noodles which are in no way inferior to usual noodles in palatability, having no problem in noodle-making by containing a fine cellulose-containing composite material as one of main ingredients and reinforcing necessary dietary fibers. SOLUTION: Noodles are made by using a fine cellulose-containing composite material in preferably 3-30 wt.% of the main ingredients, mixing the main ingredients in powders, then adding water and forming a dough to make noodles. The aforesaid composite material preferably comprises 40-70% of fine cellulose, 30-60% of digestion resistant dextrin and 0-3% of a thickening stabilizer (e.g. gellan gum). The aforementioned composite material is obtained by hydrolyzing a cellulose-based material such as wood pulp and the like to depolymerize to have 30-375 average degree of polymerization, subsequently grinding with mechanical shear (shearing force), adding digestion resistant dextrin, mixing and drying the mixture.

Title: Two-line ac contactless switch
Inventor: NODERA HISATOSHI
IPC: H03K17/945
Filed: 1977-11-11
Abstract: PURPOSE:To raise the brightness of a luminescent diode even with inductance load, by changing the position of connection of the luminescent diode when a circuit consisting of two silicon controlled rectifiers and a constant voltage diode is controlled through a sensor circuit. CONSTITUTION:A transistor 24 is turned on or off by the action of the sensor circuit 1 such as a proximity switch to control the silicon controlled rectifiers 22, 23. The cathode of a diode 32 is connected to the node of a resistor 26 with a capacitor 29, and the anode of the diode 32 is connected to the cathode of the constant voltage diode 30 through the luminescent diode 34. Current is kept by the diode 32 from flowing through the resistor 26. Thereby, the leaking current during the turn-off of the silicon controlled rectifier 22 is reduced. When the rectifier 22 is closed, current supplied to the sensor circuit 1 flows through the luminescent diode 34. Therefore, the luminescent diode 34 can be very brightly lighted on even with inductance load.

Title: Internal grinder
Inventor: NISHI KENICHI
IPC: B24B49/00
Filed: 1980-09-30
Abstract: PURPOSE: To protect a work from damage by a method wherein the preliminary tremor of an earthquake is detected and grindstone is stopped after retracting it from the interior of the work.  
     CONSTITUTION: A primary wave sensor feeds out a detection signal 9 when it detects the longitudinal primary wave, namely, the preliminary tremor of an earth- quake, resulting in that a controller 6 is inputted with a pulse 11 through a non-shot multivibrator 10 and then with a pulse 13 through a delay circuit 12. A mechanism 4 retracts the grindstone 1 from the interior of the work 2 on the basis of the pulse 11, and then mechanism 3 and 5 are operated on the basis of the pulse 13 to stop the rotation of the grindstone 1 and the work 2. Accordingly, the grindstone and the work are separated from each other before the arrival of the transverse secondary wave, namely, the mainshock of the earthquake, thereby protecting both the grindstone and the work from damage.

Title: Rotation braking device for magnetic disk
Inventor: FUJIOKA MASAHIKO
IPC: G11B19/22
Filed: 1978-11-08
Abstract: PURPOSE:To prevent a magnetic head from wearing by braking a motor for a magnetic disk at the same time as the landing of a contact start-stop type magnetic head, on detecting the rotational frequency of the magnetic disk lowering. CONSTITUTION:To the tip of rotary arm type actuator 18, contact start-stop type magnetic head 19 is fitted. On detecting the rotational frequency of magnetic disk 10 lowering, index mark detector 21 allows rotational-frequency decision unit 23 to send a rotational-frequency decrease report signal. Switch 24, connected between power supply 25 and electromagnetic brake 17, operates electromagnetic brake 17 in response to the generation of the rotational-frequency decrease report signal. Consequently, the magnetic head can be prevented from wearing because the braking mechanism is operated after the rotation of the magnetic disk decreases to a certain degree to minimize the wearing of the braking mechanism.

Title: Rotary head assembly for magnetic recording and reproducing device
Inventor: FURUKAWA HIROMICHI
IPC: G11B15/61
Filed: 1987-05-29
Abstract: PURPOSE:To uniformize the deformation of a magnetic tape over the section from the central point of the tape winding section to the tape separating point of a fixed cylinder so as to stabilize the transmission of recording and reproduced signals, by forming a projecting section at a prescribed position on the upper end face of the outer peripheral section of the cylinder. CONSTITUTION:At the midpoint of the section between the central point B of the magnetic tape 4 winding section and the tape separating point C of a fixed cylinder 5A on the upper end face 503 of the outer peripheral section of the fixed cylinder 5A, a projecting section 504 facing a head chip 101 is provided. A recessed section 505 is similarly formed at the midpoint of the section from the tape winding starting point A to the central point B. By the projecting and recessed sections 504 and 505, the clearance 14 on the bottom side of the head chip 101 becomes larger on the recessed side and smaller on the projecting side. Since the deformation of the magnetic tape 9 against the fixed cylinder 5a is stabilized and uniformized over the full tape winding section when such constitution is used, the transmission of recording and reproduced signals between the recording and reproducing head and magnetic tape can be stabilized.

Filed: 1978-11-08
Abstract: PURPOSE: To quickly perform phase synchronism for the servo circuit, by continuously changing the phase gain of the phase error signal in proportion to the phase difference between the servo system output signal and the reference signal with control signal.  
     CONSTITUTION: The saw tooth wave or trapezoid wave generating circuit 5 outputs the saw tooth wave 2 or trapezoid wave 6 with the constant current 3 inputted from the constant current source 2 when the servo system output signal 4 is inputted. The sampling generation circuit 9 produces the sampling pulse 10 with the input of the reference signal 8 and outputs it to the sampling hold circuit 7. The circuit 7 samples the saw tooth wave or trapezoid wave 6 with the sampling pulse 10 and holds it until the next pulse 10 comes to output the phase error signal 11 in proportion to the phase difference between the signals 4 and 8. Thus, the phase gain of the signal 11 can continously be changed with the control signal 1.
