Title: Device of switching and controlling feed water pump
Inventor: SHIBAYAMA TAKASHI
IPC: F22D5/34
Filed: 1989-02-06
Abstract: PURPOSE:To make it smooth to switch operation in a title device used for a thermal electric power plant, etc., by opening a lowest flow rate valve and returning the water to a condenser if the rotational speed of the water supply pump driven by a turbine exceeds its critical speed when the operation of a feed water pump driven by an electric motor and feed water pump driven by the turbine is switched. CONSTITUTION:The rotational speed Rn of a feed water pump 7a driven by a turbine is detected by a rotational speed detection device 12 and a detected speed is compared with a set value Ro in the critical rotational speed range by a rotational speed comparator 13. And, if Rn<Ro, a signal 14 of opening is inputted to a minimum flow valve 9 to open it. With this arrangement the discharge pressure from condensate pumps 2a-2c falls and the suction pressure of the feed water pumps 7a and 7b which are driven by a turbine is reduced and the total head of the feed water pumps 7a and 7b driven a turbine increases, and the rotational speed at the start of feed water goes out of the range of danger. With this constitution the operation switching becomes smooth.

Title: Method for preventing defective conveyance of cut sheet
Inventor: UJIIE YOICHI
IPC: G03G15/00
Filed: 1990-02-05
Abstract: PURPOSE:To prevent the occurrence of defective conveyance by cutting off the tip part of a paper by a given length so that at the starting of a print work, the deformed part of a photographic paper due to a direction converting roller is displaced from the tip part of a cut sheet. CONSTITUTION:At the starting of a work, a draw roller, a feed direction converting roller 15, and a conveyance roller are driven by a given amount to draw a paper 12 by a specified length L3. After completion of drawing a tip part 12c of the paper 12 is cut by the amount equivalent to a draw amount L3 by means of a cutter 30. Thus, the position of a deformed part 12b due to the converting roller 15 is displaced from a position intended to be cut and moved toward the central part of a cut sheet. A work is transferred to a normal print work, the paper 12 is conveyed and cut by the amount equivalent to one frame at a time, but the deformed part 12b is positioned at a central part in a state to be displaced from the cut part of the cut sheet. Thus, when a next cut surface passes a cut sheet insertion port, it is prevented from catching, and defective conveyance is prevented from occurring.

Title: Piezoelectric sounding body
Inventor: ISHIKAWA YUKITO
IPC: G10K9/122
Filed: 1996-02-14
Abstract: PROBLEM TO BE SOLVED: To prevent the degradation in characteristics such as reduction of a sound pressure level, instability of oscillation and the like by providing protrusion protruding closely to a supporting part side on a metal substrate being a constituting member of a piezoelectric vibration plate. SOLUTION: When a piezoelectric vibration plate 2 is bonded to a supporting part 7, a protrusion 9 protruding to the supporting part 7 side on a metal substrate 4 makes positioning for bonding to the supporting part 7 sure, and prevents horizontal deviation. Consequently, the piezoelectric vibration plate 2 is never made contact with an internal side surface of a case 1, reduction of a sound pressure level and instability of oscillation are prevented, an piezoelectric sounding body having high reliability can be obtained. Also, if there are three or more protrusions 9 formed on the metal substrate, positioning can be accurately performed.  This protrusion 9 does not only prevent vibration of the piezoelectric vibration plate 2, but also a gathering part of adhesive bonding the piezoelectric element 3 and the metal substrate 4 at a reverse side is formed by forming this protrusion 9, and adhesive strength is improved.

Title: Electrodeless discharge lamp
Inventor: DOBASHI MASAHIRO
IPC: H01J65/04
Filed: 1978-03-08
Abstract: PURPOSE: To prevent the reaction between alkali metals and luminous bulb material during the operation of a lamp and elongate the use life of the lamp by forming a luminous bulb (filled with alkali metals and inert gases) of single crystal or polycrystal alumina.  
     CONSTITUTION: Saphier end caps 4 and 5 are sealed at the end of a saphire tube 3 made of transparent single crystal alumina by a sealng agent 6 to form a luminous bulb 7. The bulb 7 is filled with an excess amount of Cs8 and argon at several Torr. The transparency of the bulb 7 enables efficient utilization of the Cs specturm. Because saphire is highly resistant to alkali, it does not react with Cs8 during operation which, if occured, would result in reduction in light transmissivity and dissipation of Cs8. Thus the use life of the lamp is elongated.

Abstract: PURPOSE: To decrease component parts of a signal extractor device and to improve reliability thereof by constituting same such that a wire memory is employed as an interface element with notice being taken of magnetic characteristics of the wire memory.  
     CONSTITUTION: When a process contact 1 is closed, an operation of a change-over device 15 produces an interruption of a word electric current IW, and a positive voltage is caused to appear in a beam line 10 as a differential voltage at the time of a rising edge of the word electric current IW. An output voltage e 0  of a logic level is obtained from a sense amplifier 12. The output voltage e 0  is output with being insulated from a process signal. On the other hand, when the process contact 1 is open, there flows no word electric current IW so that an operation of the change- over device 15 does not cause a voltage to be generated in the beam line 10, resulting in no change in the output voltage for the sense amplifier 12. Accordingly, make and break conditions of the process contact 1 are converted into logic signals electrically insulated therefrom through the wire memory 10.

IPC: B65H5/06
Filed: 1992-02-13
Abstract: PURPOSE:To prevent the edge part of an original from being rubbed by a feeding roller and to prevent the original from being damaged by providing a paper guide at the position of the feeding roller in parallel with an original carrying surface, passing the original on the upper surface of the paper guide and arranging the original passing surface of the paper guide on an upper side than the original carrying surface. CONSTITUTION:The feeding rollers 1a and 1b are constituted of rollers which are paired with each other. Then, the upper surface B of the paper guide is arranged so as to be positioned on the upper side than the carrying surface A. Since waviness occurs to the returning original 11b between the passing part of the feeding roller and the passing part of paper guide, stiffness is given to the original 11b and the original 11b is smoothly carried. When the original 11b is perfectly fed from the rollers 1a and 1b, the trailing edge of the original 11b is lifted more upward than the carrying surface A along the paper guide. Thus, the trailing edge part of the original 11b is loosened and brought into contact with the surface of the upper side roller out of the rollers 1a and 1b. As the result, the trailing edge of the original is not rubbed by the roller.

Title: Method for suppressing coil magnetic field fluctuation
Inventor: KOMATSUGI KAZUNARI
IPC: G01R33/20
Filed: 1988-02-08
Abstract: PURPOSE:To remove the ripple of a coil current and to cancel a magnetic field fluctuation accompanying this without using a large filter, etc., by feeding respectively from a voltage type PWM inverter having a carrier waveform having the phase difference of 90 deg. mutually to first and second coil groups. CONSTITUTION:A control signal (direct current level) compared with the carrier waveform of an inverter is set and the output voltage of the inverter is set low. At this time, when the output current of respective inverters 2A, 2C and 2B, 2D, namely, only the ripple of a current to flow at coils 1A, 1C and 1B, 1D is extracted, the ripple is comparatively made layer when respective coils are individually watched. However, since the current of respective coils 1A, 1C and 1B, 1D is mutually dislocated to 90 deg. by the phase difference of the carrier waveform, the ripple of these synthesizing current is eased more than the individual current. Consequently, the grade magnetic field based on the synthesizing coil current can be made into the current in which the fluctuation due to the carrier waveform is comparatively small.
