Title: Servo controller
Inventor: AWAYA ICHIRO
IPC: G05B11/26
Filed: 1989-03-03
Abstract: PURPOSE:To produce the friction eliminating force with no delay by preparing a frictional characteristic model part to obtain the frictional force and a unit pulse generating part to produce a command for the pulsative frictional resistance force when a delay of response is produced. CONSTITUTION:A servo controller 1 includes a frictional characteristic model part 9 to obtain the frictional force and a unit pulse generating part 10 to produce a command for the pulsative frictional resistance force when a delay of response is produced by friction. In other words, the data having the force larger than the frictional force is prepared to instantaneously produce the pulsative frictional compensating force when a delay of response due to the influence of the friction is produced. Thus the influence of the friction is eliminated. Then the control force is quickly eliminated to the friction and the influence of the friction is instantaneously compensated with no loss of the integrated time.

Title: Dama communication system
Inventor: UENO EIKO
IPC: H04B7/208
Filed: 1989-03-03
Abstract: PURPOSE:To prevent the occurrence of the deviation of an actual internal state of a slave station from the internal state of the slave station recognized with a master station by making the internal state of the slave station coincident forcedly with the content of station information when the master station receives a signal opposed from the content of the station information from the slave station. CONSTITUTION:Suppose that an error is caused by a signal sent from a slave station 3a on a CCS line and a closing signal 33a is arrived, a master station 2 closes the state of the relay line trunk 9a of the slave station 3a and sends a closing acknowledging signal 34 to the slave station 3a. Since the relay line trunk 9a is not actually closed, a line assignment requesting signal 31 may or may not be sent. When the signal 31, is received, the master station 2 discriminates that there is any error in the closing signal 33a or the line assignment requesting signal 31. Then the master station 2 makes the state of the relay line trunk 9a idle, uses the relay line trunk 9a as the object of line assignment control and sends a release acknowledging signal 35 to the slave station 3a. Thus, the deviation between the actual internal state of the slave station and the internal state of the slave station recognized by the master station is corrected automatically.

Title: Oil level gauge
Inventor: DOUHOU MASANORI
IPC: G01F23/04
Filed: 1998-02-15
Abstract: PROBLEM TO BE SOLVED: To prevent a tip scale part from touching the inner wall of a guide curved pipe and hence improve measurement accuracy when a gauge body is inserted and forced in and is pulled by providing a pair of projections and one projection at the scale part formation side and at the opposite side of an oil level gauge body, respectively. SOLUTION: A pair of projections A and A are arranged and fixed in a zigzag while sandwiching a projection B on an outer surface 7 in that one projection B and a scale part 18 are formed at the enter of a body inner surface 6 in nearly a plate shape with the minimum radius part 9 as a boundary at the curved part of an oil level gauge body 5 that can be elastically deformed. In this case, the distance between the top parts of the projections A and B is longer than the inner diameter of the guide curved pipe when viewed from the longer direction of the gauge. However, since the projection shrinks by force-in since it is made of an elastic body and hence can be inserted freely in a guide curved pipe. Also, since there are two projections A and one projection B, deflection is made toward the side of the projection B.  Therefore, when the oil level gauge body 5 is forced in or is pulled out, it is elastically deformed as shown by a broken line and the tip scale part 18 can be separated from a guide pipe wall.

Title: Manufacture of lead bar for magnetron
Inventor: NISHIYAMA CHIKAO
IPC: H01J23/14
Filed: 1990-02-28
Abstract: PURPOSE:To provide a lead bar the tip end shape of which is suitable for butt welding, at low cost by polishing a molybdenum bar by means of barrel grind ing, forming each end section into a spherical shape, and thereby eliminating a need for shaping each end section by centerless grinding and a lathe. CONSTITUTION:A molybdenum bar is polished with sodium hydroxide solution by means of electro-polishing, is cut off to a specified length, and is polished together with water for about 5 hours by the use of a centrifugal barrel machine (high speed centrifugal fluid grinder). Each tip end section of the molybdenum bar is selectively worn by polishing as mentioned above so that it is formed into a spherical surface. Thus, each of the tip end sections 3a and 3b of the lead bar 3 is formed into a spherical surface, the whole surface of it is covered with a nickel plate layer 10, which thereby effectively prevents the lead bar made of molybdenum from being oxidized, and both solderability at foot section and weldability at the upper end section are concurrently enhanced. This thereby eliminates a need for centerless polishing of the lead bar, which result in an reduction of yield with a lot of manhours consumed, the cost of manufacture can thereby be lowered.

Abstract: PURPOSE:To secure a substrate inserter easy to insert a substrate into a card box and to extract this substrate inserter with one hand alone by installing a slide mechanism, where a pushing fitting slides on a stationary fitting when a handle part is pulled nearer to an arm part, and a reset spring of the stationary fitting, respectively. CONSTITUTION:If a handle part 2 is not grasped tight, a substrate inserter is easily inserted into an inner part of the card box as an interval between two stationary fittings 1 is narrower than that of a flange 9a of a card box 9. If the center of this handle part 2 is grasped by one hand, an interval between these stationary fittings 1 and 1 is widened with work of a slide part 8, and thereby the stationary fitting 1 is engaged and held by the flange 9a of the card box 9, and if it is further grasped tight, a pushing fitting 4 is advanced forward, pushing both ends of a substrate 10 thereinto with uniform force, and this substrate 10 is surely inserted thereinto. After insertion, if force is loosed, the stationary fitting 1 is put back to the original position by dint of spring action, and since the interval becomes narrowed again, the substrate inserter is easily extractable from the car box 9.
