IPC: F16L55/16
Filed: 1993-07-26
Abstract: PURPOSE:To prevent generation of deflection between a lining material and a conduit by forming a circular protrusion protruded inward at a certain depth of the terminal of the conduit, then providing the lining material on the inner surface of the conduit, fitting a development ring to a position on the pipe end side close to the circular protrusion, and developing it. CONSTITUTION:A circular protrusion 3 protruded inward is formed in an inner surface of a position at a certain depth of a terminal part of a conduit 1 such as a gas guide pipe or the like embedded under the ground, and a lining material 2 is lined on the inner surface of the conduit 1. The position of the circular protrusion 3 in this lining material 2 is formed to be a swollen part 4 swollen inward. A development ring 5 of a rigid ring of metal or the like is then installed on the inner side of the lining material 2 on the pipe end side close to this swollen part, and this is developed from the inner side to be plastically deformed, so the lining material 2 is held between the conduit 1 and the swollen part 4. Generation of deflection at the terminal of the lining material can thus be prevented in the case where the lining material 2 is not strongly bound to the conduit 1 for the whole length of the conduit 1.

Filed: 1989-08-08
Abstract: PURPOSE:To prolong the life of an ink ribbon by adjusting the impact strength of a printing hammer in accordance with the detection result of the ink content of the ink ribbon. CONSTITUTION:A detector 3 sorts the density into 3 stages in accordance with the ink content and, correspondingly to the stage, outputs a detection signal to a control part 2 through control lines 101 - 103. When receiving a change-over instruction signal from the control part 2 through a control line 112, an impact change-over device 4 supplies an electric power to a hammer group 5 through a supply line 121 and controls the oscillating strength of the hammer group 5 to be stronger than that when receiving a change-over instruction signal from the control part 2 through a control line 111. In this manner, an electric power supplied from the impact change-over device 4 to the hammer group 5 is adjusted in accordance with the ink content of the ink ribbon in use detected by the detector 3, whereby the oscillating strength of the hammer group 5 is decreased with the large content of the ink ribbon. Thus, the life of the ink ribbon in use can be made twice or more longer than that in a prior art.

IPC: G03G15/04
Filed: 1984-09-28
Abstract: PURPOSE:To inform of an operator that the copying machine is under an automatic exposing operation by clearing the display of set data during the time when the setting operation of copying image density is executed by automatic exposing and displaying the set data after the setting operation of the copying image density ends. CONSTITUTION:Whether an automatic exposing mode is selected or not is discriminated and if the automatic exposing mode is selected, the display of the data on the set copying image density in a display part is cleared and the setting operation of the data by a key for setting the copying density on a display panel is prohibited by a data input prohibiting circuit 84. The display of the data on the set copying image density in the display part is cleared during the time when the automatic exposing operation is executed and therefore the data on the set copying image density is not known at all in the case of executing the copying operation and this state is usable as the display of the executing state of the automatic exposing.

Title: Ribbon lift mechanism of typewriter
Inventor: ARAI TOMIO
IPC: B41J35/14
Filed: 1984-09-29
Abstract: PURPOSE:To simplify a mechanism by dispensing with the cam for a wobbler eccentric, by operating the wobbler eccentric for performing a minute amount of lift by using the change in the rotary angle of a lift cam being a main lift mechanism as a signal. CONSTITUTION:When a cam shaft 11 is driven by a stepping motor and a ribbon lift cam 10 is revolved, a ribbon is lifted at a fundamental truck position. When the ribbon lift cam 10 is rotated by 240 deg., the projection pat 50 of the cam 10 pushes a wobbler lever 51 which is, in turn, revolved around a shaft 52 to push a wobbler eccentric 16. At this time, the pawl 51a on the upper surface of the lever 51 is engaged with the groove 55a of a holding member 55 and the ribbon is lifted at a shifted truck position. When the cam 10 is further rotated, the pawl 51a is engaged with the separated groove 55b of the holding member 55 and the ribbon is lifted at a further shifted position. When the cam 10 further rotates and there is no groove corresponding to the pawl 51a, the engagement of the lever 51 and the wobbler eccentric 16 is released and the ribbon is returned to a home position.

Title: Water cut-off method for construction joint of underground concrete structure and water cut-off structure
Inventor: KAWAGUCHI HIROYUKI
IPC: E04G21/02
Filed: 1999-07-19
Abstract: PROBLEM TO BE SOLVED: To cut off water by corresponding to a joint opening amount of a construction joint by forming a groove on a tip face on a following concrete wall side and arranging a bentonite water cut-off material expanding due to the reaction with water in the groove to place and join a following concrete wall. SOLUTION: A bentonite water cut-off material 15 is used as a water cut-off material and expands due to the reaction with underground water when the underground water enters a construction joint of an underground concrete structure. Furthermore, the construction joint is blocked due to clogging of the construction joint, and the construction joint is blocked to cut off water even when a joint opening amount of the construction joint is large. In this case, it is unnecessary to predict the construction joint opening amount of the construction joint in advance to correspond flexibly in accordance with the construction joint opening amount. Even when a concrete wall is wet, the bentonite water cut-off material 15 reacts with water, expands, and adheres closely on the concrete wall to cut off water.  Consequently, it is possible to position and fix the bentonite water cut-off material 15 easily at a low cost by arranging the bentonite water cut-off material 15 in a groove 21.
