Patent JP-S62140278-A (JP)
Title: Head positioning control system
Inventor: NISHINOMIYA TAKESHI
IPC: G11B21/10
Filed: 1985-12-13
Abstract: PURPOSE:To prevent the performance of head positioning control from deteriorating by stopping the transmission of an integral value sent out of an integration circuit which is utilized for a signal for the position correction of a head for a prescribed time right after coarse control is switched to fine control. CONSTITUTION:When a control mode switching circuit 3 sends out a fine control signal, a switch 17 sends out the output of an adding circuit 15 to a motor driving circuit 18, but a delay circuit 26 delays a control signal by a prescribed time and then sends it out to a switch 25, which is operated. Therefore, the current integration signal obtained by integrating a motor current signal detected by a motor current detecting circuit 19 by an integration circuit 14 is delayed by a prescribed time and inputted to the adding circuit 15. Consequently, the influence of the large apparent moving speed of a head upon a position correcting signal is removed. Thus, the performance of head positioning control is prevented from deteriorating.

Title: Shutoff nozzle for injection molding machine
Inventor: MITSUI MASATAKA
IPC: B29C45/23
Filed: 1995-10-27
Abstract: PROBLEM TO BE SOLVED: To provide a shutoff nozzle free from a resin leakage and capable of withstanding a long time of use by forming a cooling passage in parallel with the axial core direction, from both end parts to the center part, of each of a housing and a rotary valve. SOLUTION: The surroundings of a molten resin passage 10 is properly heated by a cartridge heater inserted into a heater mounting part 12 without disordering a normal melting and circulating process. However, if the remote surroundings of the molten resin passage 10 are heated by the cartridge heater, the viscosity of a resin is reduced, and the leakage of the resin easily occurs under the effect of rising of resin pressure at the time of starting dwelling. In order to prevent this phenomenon from occurring, cooling parts 33, 40 are provided in a rotary valve 2 and a housing 4 to cool only the remote peripheral part of the molten resin passage 10. Thus, a cooling passage 34 is arranged in parallel with the axial core running from both end parts to the center part of the rotary valve 2.

Title: Method for dehydrating organic sludge
Inventor: YAMAGUCHI MIKIMASA
IPC: C02F11/14
Filed: 1984-12-27
Abstract: PURPOSE:To increase remarkably the capacity of existing sludge treating equipment by adding an acidic flocculant to org. sludge to enhance the filtrability, concentrating the sludge by a filtration and concentration apparatus and then dehydrating mechanically the sludge. CONSTITUTION:About 8.2wt% ferric chloride, etc., is added as an acidic flocculant to org. sludge, and the sludge is concd. by using a filtration and concn. apparatus. The putrefaction of sludge can be controlled for a long time by the addition of the ferric chloride, etc. About 30wt%, based on the solid matter in sludge, slaked lime is added to the concd. sludge as a filter aid, and mixed sufficiently.

Abstract: PURPOSE:To evaluate resistance against electromigration and the like based on the results of measurements by using converged ion beams, forming voids at arbitray sizes, depths and densities at the intended places of the internal wirings of a semiconductor device, and making a current flow through the wiring. CONSTITUTION:Voids 5 and 6 are formed at the intended places of internal wirings 1 and 2 of a semiconductor device with converged ion beams (FIB) 4. A measuring system 3 for measuring the changes such as wire breakdown, increase in resistance value and the like is formed between the wirings 1 and 2. Thereafter, the semiconductor device is placed in the environment of constant-current stress, high temperature and high humidity for a long time (usually 1,000-2,000 hours) continuously. Thus tests are conducted. As a result, the phenomena such as wire breakdown in wirings and the increase in resistance values due to electromigration and the like in the wirings 1 and 2 of the semiconductor device are induced and generated by the factors of the voids 5 and 6 formed with the FIB 4. In this constitution, the changes such as the wire breakdown between the wirings 1 and 2 and the increase in resistance value are measured with the measuring system 3. The statistical analysis of the defects can be performed based on the measured results.

Abstract: PURPOSE:To vary a variable prize-winning device in a profitable state for a player by generating a prize mode when a result of operation in the third arithmetic and storing means amounts to the number of pinballs set by a difference number-setting device. CONSTITUTION:After a shot pinball falls into a prize-winning pocket, it is detected by a safe pinball sensor 52 provided on a safe pinball-dropping route 51, and then the number of prize pinballs set by a setting switch 65 for them is added on a prize pinball memory of the second arithmetic and storing means.

Whenever a safe pinball or an out pinball is detected by a retrieved pinball sensor 55 provided on a retrieved pinball-dropping route 54, the number of 1 is added on a retrieved pinball memory of the first arithmetic unit and resister in a CPU 57. When the value on a memory of a retrieved pinball signal exceeds the number of 10, it is deducted by the number of 10 after the retrieved pinball signal is outputted. A difference of the number between retrieved and prize pinballs is operated and stored by a difference-operating resister of the third arithmetic and storing means in the CPU 57. When the above difference is equal to a difference of the number between retrieved and discharged pinballs, a special game is started.
