Title: Phase adjustment device, phase adjustment method and display device
Inventor: MORITA HIDEO
IPC: G09G3/20
Filed: 1997-09-02
Abstract: PROBLEM TO BE SOLVED: To considerably improve the operability by counting number of clocks between two prescribed pixels in an optional horizontal line of an image over a plurality of frames and adjusting the phase of the clock signal to be in matching with a phase of an image signal depending on the count result. SOLUTION: Under the control of a control section 6, the phase is adjusted depending on the result of each counter of an H counter circuit 4 and a V counter circuit 7. When the control section 6 receives a count signal S6 from the H counter circuit 4, the control section 6 starts a phase adjustment processing procedure and allows the V counter circuit 7 to select a desire line. The control section 6 measures a clock number within a count period of a selected line in a 1st frame and measures a clock number within a count period of the selected line even in a 2nd frame. The control section 6 discriminates whether or not number of blocks is equal to a total frequency division number of 1H line and the control section 6 discriminates whether or not the difference of the clock number is two or over when the former discrimination indicates a negation result.

Filed: 1998-08-25
Abstract: PROBLEM TO BE SOLVED: To unnecessitate the erasing operation of a message window picture by automatically erasing the displayed message window picture after a fixed display time elapses. SOLUTION: When the message window picture is displayed, a controller 4 judged whether or not the screen reports an important message which is not suitable for automatic erasion such as 'system abnormality' or the like. Unless the message is the important one, the controller 4 issues sound such as the beep one or the like for catching user's attention by controlling a sound issuing device 5. The controller 4 obtains the length of a message character string on the displayed message window picture. Then, the controller 4 waits for time elapse only by reference time 'To' and also waits for another time elapse by 'character string length × T1 (T1 is an additional time)'. Then, the controller 4 erases the displayed message window picture.

Abstract: PROBLEM TO BE SOLVED: To prevent a back flow after the election of a grout, and to generate cracks in the horizontal direction surely without vertically expanding the jet of the grout by extending the opposed end sections of upper-lower two elastic sleeves to the outside in the radial direction respectively and forming lip sections. SOLUTION: Lip sections 12, 12 elongated to the outside in the radial direction are formed oppositely to elastic sleeves 11, 11 for a sleeve valve. Consequently, parallel surface sections D1 by the lip sections 12, 12 are formed to a nozzle D pushed open by a grout C and formed at the time of grout injection. Accordingly, the grout C is guided by the parallel surface sections D1 at the time of grout injection, and ejected as a jet E in the horizontal direction under the state of an approximately laminar flow. Cracks in the horizontal direction are generated surely in a ground by the jet E, and the effect of grout injection is improved. Pressure is applied to the upper and lower surfaces of the lip sections 12, 12 after grout injection, and the parallel surface sections D1 are fast stuck and a back flow is prevented.

Abstract: PURPOSE:To suppress generation of iron loss in a core by dividing the core into a first core of the front end side of an armature and a second core of the rear end side of the armature, and forming a laminated structure. CONSTITUTION:A core 12 for attracting a bias leaf spring (BB) 7 and an armature (AC) 10 is formed at an attraction point A side for attracting the BB7 and AC10, i.e., the part of the front end side of the AC10 as a first core 12c, and formed of a material having high saturated magnetic flux density.
