Abstract: PURPOSE: To improve workability by successively disposing a gripper hung down by a wire, an epicycle speed increasing gear, a cylindrical support, from which a fit is projected, and an excavating tool downwards in a casing tube in a coaxial manner. CONSTITUTION: When a hollow excavator 20 is lowered into a casing tube 01 and a lower end is grounded, a wire 010 is loosened and a weight 3 is brought down, and a gripper 6 is pushed against the inner wall of the tube 01 by an upper link 7, thus fixing the excavator 20. A support 23 is fastened to the ground, and a screw 28 is pushed into the ground while rotating the tube 01. The speed of a ring gear 14 is increased and the revolving torque of the ring gear 14 is transmitted to a sun gear 11 through a planetary gear 13 at that time, the screw 28 is driven and the ground is excavated. When the screw 28 is pushed and the revolution of the sun gear 11 is fixed and the tube 01 is turned, the outer circumference of the screw 28 is excavated by the support 23. Accordingly, vibrations can be reduced, and even the hard ground can be excavated.

Title: Foaming toner
Inventor: NARISAWA TOSHIAKI
IPC: G03G9/08
Filed: 1979-10-09
Abstract: PURPOSE: To increase the fixing area of a toner and raise the density of an image by adding a foaming agent to the toner, which foams at a suitable temp. to foam the toner in fixing.  
     CONSTITUTION: To a toner is added an adequate amount of a foaming agent which does not foam in a toner manufacturing process, a developing process or other process and foams at 90W320°C in a fixing process. The agent includes azo compounds such as azobisformamide which foams at 190W210°C and azobisisobutyronitrile which foams at 110W115°C, nitroso compounds, azide compounds and hydrazide compounds. Thus, the volume of the toner is increased 1.2W2 times by foaming, and simultaneously the toner is fluidized to expand the fixing area. Accordingly, this foaming toner gives a fixed image of higher optical density as compared to a conventional toner used in the same amount.

Title: Volume controller
Inventor: YOSHIJI SHIYUNJI
IPC: H03G1/02
Filed: 1977-10-27
Abstract: PURPOSE:To enable the control between the maximum volume and minimum volume determined by a viewer, by exercising the control of a control signal with its pulse width varied on a remote volume controller. CONSTITUTION:One control signal with its pulse width varied is inputted to the volume control input ot turn ON-OFF transistor Tr7. While Tr7 is OFF, capacitor C4 is charged via variable resistance 1 and fixed resistance R2, and while Tr7 is On, on the other hand, the chrge of C4 is discharged via R2 and R3. As for input- output characteristics of sound amplifier 9, supplying a volume control signal from the remote controller results in that the input of amplifier 9 will be at maximum and its output will be at minimum with Tr7 OFF since the output voltage decreases as the input voltage increases. As shown by lines (a), (b) and (c), they concentrate upon one point with the sound control input small, so that minimum sound will be fixed and the maximum sound will depend upon resistance 1. The control between this maximum sound and minimum sound is exercised with a control signal.

Title: Safety device for gas appliance
Inventor: ITO YOSHINORI
IPC: F23K5/16
Filed: 1989-05-23
Abstract: PURPOSE:To improve safety by a method wherein a disengagement member is formed of a shape memory material and a part thereof changing in a shape when a set temperature is exceeded is fitted to a position whereat it pushes the outside of a gas cylinder. CONSTITUTION:A gas cylinder 1 is connected to a connection port 10 of a governor 9, a flange 3 is held magnetically by a magnetic holding mechanism 11 and fitted, and the title device operates when the peripheral temperature of the gas cylinder rises abnormally due to extraordinary handling while a gas appliance is employed. When the temperature rises above a set value, a concretely, the shape of a disengagement member 14 changes into a shape memorized beforehand and the member pushes the rear of front part of the gas cylinder 1 by the active end part 17 thereof, so as to disengage the gas cylinder 1 held by magnetism. Consequently, a valve nozzle 4 is made to project, so as to stop discharge of a gas, and combustion is stopped. Even when the gas cylinder is heated due to extraordinary handling of the gas appliance, according to this constitution, the disengagement member operates when the set value determined beforehand is exceeded, and it pushes the gas cylinder, so as to remove the connection. Therefore combustion can not be continued and, accordingly, the temperature does not rise further. Thus, safety is much improved.

Title: Display case
Inventor: TAKENAKA KENGO
IPC: A47F3/04
Filed: 1995-05-29
Abstract: PURPOSE: To efficiently cool and cold insulate in a display case without drawing the atmosphere into the case by allowing a straightening plate to protrude into a vent passage to form a cold air curtain in an opening on the inner surface of a ceiling wall this side of the air outlet of the passage. CONSTITUTION: A straightening plate 8 is mounted on the inner surface of the corner 5e of the ceiling wall of a vent passage 5b. The air stream flowing forward in the passage 5b is prevented at the outside by the plate 8 to partly become a turbulent flow to be decelerated at the speed and fed to the plate 8. Accordingly, the cold air curtain 7b formed in the opening 1a by straightening by the plate 8 is decelerated at the outer flowing speed from the inner flowing speed. The height (h) of the plate 8 is set to 1/6 to 1/3 of the height H of the passage 5b. Thus, the drawing of the outer curtain 7c and the outer atmosphere by the curtain 7b is excluded, and the case can be efficiently cooled and cold insulated.

Filed: 1984-06-26
Abstract: PURPOSE:To dissolve the shortage of power of a motor by reconstructing the outside part of the sealed container of a Freon compressor equipped with a pipe for introducing Freon gas during compression cycle and connecting said pipe to a suction pipe and using said Freon compressor as helium compressor. CONSTITUTION:When the captioned apparatus is used as Freon compressor, the part before the gate valve 5 of a cylinder 2 and the outer peripheral space 10 of the cylinder 2 in a container 1 are connected through a short pipe 9, penetrating through a sealed container 1. Further, at the introducing port of a pipe 13 opened to the cylinder 2 before the pipe 9, the connection to a separator is realized. When the captioned apparatus is used as helium compressor, the pipe 13 is reconstructed so as to be connected to a suction pipe 8, and helium gas is used as working fluid in substitution for Freon gas. Therefore, in a space 6 in compression cycle, a portion of the inside gas returns into the suction pipe 8 having a low pressure through the pipe 13, and the amount of compressed gas in the space 6 reduces, and therefore, the power necessary for the compression of a motor 4 is reduced, and the shortage of power of the motor which is generated in the case when the Freon compressor is used as helium compressor can be dissolved.

Abstract: PURPOSE: To dispense a frozen dessert product by setting a chamber having a specified volume, determining the time in which the chamber is filled with a substance, distributing the substance only for the total time which is multiples of the time for determination to easily and inexpensively control the dispensing. CONSTITUTION: When a substance of a pre-selected volume larger than a specified minimum value is dispensed from a supply source to the selected point, a chamber of a specified volume not exceeding the minimum value is set. Then, the substance is distributed in the chamber with a specified flow rate to determine the time required to fill the chamber. Then, the substance is distributed to the selected point for the total time which is multiples of the time of determination. The multiple is equal to the multiple smaller than the ratio of the pre- selected volume to the chamber volume. When the total time is completed, the distribution is stopped, and the whole volume of the chamber is discharged to the selected point. In implementation, a frozen dessert dispensing apparatus 10 provided with a dispensing station 12, a bulk product section 14 and a control section 16 is used.
