Inventor: BABA TAKEKAZU
IPC: E02D3/12
Filed: 1994-12-28
Abstract: PURPOSE: To make sufficient stirring and mixing without making rotating together not only in the direction parallel with an excavation shaft and in the vertical direction thereof by revolving multistage stirring blades arranged up and down alternatively in the opposite direction each other. CONSTITUTION: Since an outside shaft 11 and an inside shaft 12 are revolved in the opposite direction each other, stirring blade bodies 15 and 16 following the rotation of the outside shaft 11 and stirring blade bodies 17 and 18 following the rotation of the inside shaft 12 are revolved in the opposte direction each other, and excavated soil and hardener are stirred to mix. Then, linear stirring blades 16 and 17 formed in the shape of a plate or a blade as nest of boxes incorporated in frame shaped stirring blade bodies 15 and 18 formed in a roughly U-shape pass while they are inverted. By the constitution, alternatively arranged up and down mutistage invertion stirring blade construction is formed, and sufficient stirring and mixing are made. Since both radial and axial directions of an excavation shaft 10 are cut off, common rotation of the stirring blades 15-18 is prevented.

Title: Optical connector
Inventor: TAKIZAWA KAZUHIRO
IPC: G02B6/36
Filed: 1996-12-06
Abstract: PROBLEM TO BE SOLVED: To facilitate the cleaning of the connection end face of the ferrule inside an adapter, by constituting an optical connector so that a guide pin relatively protrudes from the connection end face and to move into the guide pin hole of the ferrule on the opposite side corresponding to the backward movement of the ferrule inside the adapter when the ferule on the opposite side is inserted into the adapter. SOLUTION: When a ferrule 2 of an optical connector plug 20B is inserted from an inserting port 4 in the case of connector connection, the ferrule 2 inside the adapter 3 is pushed by the top end of the inserted ferrule 2, and the ferrule 2 is moved back against the energizing force of an energizing means 16. At such a time, the guide pin 8 relatively protrudes from a connection end face 10 and moves into the guide pin hole of the optical connector plug 20B on the opposite side corresponding to the backward movement of the ferrule 2. Thus, both the ferrules 2 are abutted and connected while being aligned. Then, by engaging an elastic pawl 9 with a rear end flange part 2a of the ferrule 2 on the opposite side, the ferrules 2 are prevented from being dropped and the state of stable connection is maintained.

Title: Speed controller for induction motor
Inventor: OGAWA HARUTAKE
IPC: H02P21/36
Filed: 1990-11-27
Abstract: PURPOSE:To prevent a speed control system from entering into unstable state, even if the gain of the speed control system in a speed controller is increased in a mechanical system containing gears, by a constitution wherein the speed controller switches the gain of the speed control system when a switch selecting means switches a switch selectively. CONSTITUTION:In a speed controller, an acceleration controller 13 determines the acceleration ACC of a device based on a speed detected through a speed detector. In case of acceleration/deceleration or variation of load, acceleration takes place on the side of a load device and since the speed response is required to be increased, a switch 16 is closed to increase the gain in speed control. According to the constitution, a more linear control system is realized by switching the gain according to respective stages even when a nonlinear system, e.g. backlash of gear, exists in the control system.

Title: Printer
Inventor: SHIBATA KIYOSHI
IPC: B41J19/18
Filed: 1998-11-18
Abstract: PROBLEM TO BE SOLVED: To shorten print time by shifting a recording head from a home position to the start point of each line recorded at a start/end point recording section when each line of a print data is printed and shifting the recording head to the home position when it is shifted to an end position recorded at the start/ end point recording section. SOLUTION: When printing of each line is ended, a recording head is shifted to a home position. Since the recording head is shifted is shifted from the end position B1 of line I to the start point A2 or end point B2 of line I+1 before printing of the line I+1 is started, the shifting distance is shortened and thereby printing time is shortened. The recording head can be shifted between the start and end positions repeatedly and alternately such that the recording head is shifted from B1 to B2 before a line is printed and then it is shifted from A2 to A3 before another line is printed.

Title: Projection aligner
Inventor: KAWASHIMA TAKASHI
IPC: H01L21/027
Filed: 1990-11-28
Abstract: PURPOSE:To obtain a projection aligner equipped with an illuminance meter capable of measuring the illuminance distribution in each process stage, without extending the movable range of a specimen stand stage, by installing a photodetector in a retainer of an object to be exposed. CONSTITUTION:Illuminace distribution is usually measured at the beginning of a lot. A process wafer (irradiation plate) 25 is set on a horizontal part 14a by a wafer loader, and vacuum-sucked by a vacuum pump. At this time, a pin hole 19 of the process wafer 25 coincides with a pin hole 18. A shutter is opened in the state that a reticle is taken off; a wafer stage 12 is two- dimensionally moved on a horizontal surface by using a laser interferometer; illuminance of each grating point of an exposure field is measured in order with a photodetector 22. After the illuminance distribution is measured in this manner, a reticle is prepared; wafers 25a subsequent to the first wafer of the lot are actually exposed; thus a mask pattern is formed. Hence the accurate illuminance distribution corresponding with the wafer which is exposed in each process can be obtained.

Title: Method for detecting fault in transmission line of communication system
Inventor: FUKUDA YOSHIMASA
IPC: H04L69/40
Filed: 1995-12-18
Abstract: PROBLEM TO BE SOLVED: To prevent production of a call loss even when a fault takes place in a transmission line in the communication system where a D-channel signal is sent between 1st and 2nd communication equipments via a primary group interface. SOLUTION: When no expiration of a timer T309 is discriminated in the confirmation as to whether or not the timer T309 expires, whether or not a fault takes place frequently is confirmed. In this case, it is preferable to confirm whether or not faults of a prescribed number of times or over take place within a prescribed time as criterion data to discriminate a fault of D-channel to be in a fixed fault. When it is confirmed that faults of a prescribed number of times or over take place within a prescribed time, an initial setup request of layer 3 is started and transmitted. On the other hand, when it is confirmed that faults of a prescribed number of times or over does not take place within a prescribed time, it is discriminated that the fault is not a fixed fault and a state notice or a state inquiry procedure is executed.

CONSTITUTION:The two through-holes 2 are bored in proximity in the hollow rubber ball 1. One end of the cord 3 is inserted into both through-holes 2 and is tied to the intermediate wall 4. The other end of the cord 3 is inserted into a pipe arm 5 and is successively connected to a spring 8, a swivel 9 and one end of a base cord 11 via plural connectors 6, 7. Further, the other end of the base cord 11 is fixed to a clamp 10 at the base of the pipe arm 5. Then, the rubber ball 1 flies in a prescribed direction and falls to the prescribed direction together with the pipe arm 5 when the rubber ball 1 is hit by a racket at the time of training tennis. At this time, the deformation of the rubber ball 1 is facilitated by the effect of both through-holes 2. The cushion property is thus improved and the breakdown of the tied part of the cord 3 is prevented.
