Title: Ejector device for magnetic recording and reproducing device
Inventor: YAMASHITA KOJI
IPC: G11B15/675
Filed: 1985-10-08
Abstract: PURPOSE:To absorb effectively the excessive force applied to a tape pack during a course between a mobile dish and an overstroke mechanism, by providing a slider which absorbs the excessive force. CONSTITUTION:The excessive force is applied to a mobile dish 3 to push it into a machine while the dish 3 is moving to a position where the ejection is through with a tape pack 100. Thus the pack 100 first abuts on a pawl 27 of a slider 25 to push this pawl and moves against the force of a tension spring 30 to absorb and reduce the applied force. Then the slider 25 moves and the rear end part of a slit 28 formed to a slider main body 26 moves up to a set position to abut on a guide pin 29 provided to the dish 3. Under such a condition, the front end part of the pack 100 is projected over the front end part in the push-in direction. When the larger excessive force is applied, the dish 3 moves together with the pack 100 since the 2nd driven gear 18 can be revolved. Then the 3rd driven gear 23 having an arm 24 is revolved and the gear 18 revolves while winding a torsion spring 22 to absorb and reduce the excessive force.

Title: Surface acoustic wave filter
Inventor: YAMADA JIYUN
IPC: H03H9/145
Filed: 1983-11-30
Abstract: PURPOSE:To eliminate the need for control and at the same time to attain miniaturization of a surface acoustic wave filter, by having the incomplete unidirectively of an electrode and therefore increasing the range of normalized conductance. CONSTITUTION:At least one of roller screen type input and output electrodes is connected to two electrodes which are set so as to produce a phase difference of phiM radian in terms of space via a phase shifter which gives an electrical phase difference phiE radian to those two electrodes. At the same time, the sum phiM+phiE of above-mentioned phase differences is set unequal to radian. When a scale (a) of directivity is increased, an area (b) where a prescribed reflected wave suppressing level is satisfied is increased. Furthermore the (b) moves to the larger side compared with a case (a=0) of the complete unidirectivity. In other words, a prescribed phase difference is secured for both the arrangement of electrodes and the phase shifter. Thus the unidirectivity becomes incomplete. This can increase the selection range for the radiation conductance of the electrode or an external load conductance which suppresses an undesired reflected wave down to a desired level.

IPC: H05B37/02
Filed: 1992-08-24
Abstract: PURPOSE:To change brightness of illumination loads smoothly even if a changing period of transmitted light dimming levels becomes large. CONSTITUTION:Signals to show light dimming levels to light dimming units 41-4n are transmitted to a light dimming unit panel 31 from a light dimming console 32 by means of multiplex transmission.

Title: Abnormal synchronizing signal elimination method
Inventor: KIM BYEONG-SOO
IPC: H04N19/00
Filed: 1998-08-07
Abstract: PROBLEM TO BE SOLVED: To detect only normal synchronizing signals by detecting specified pattern data from input data, judging them as synchronizing signals, when the detected synchronizing signals are provided with a periodicity while otherwise invalidating them. SOLUTION: For input data, a synchronizing signal is detected through the use of a reproduction clock (s101). Whether or not the detected synchronizing signal is provided with a periodicity is inspected (s102), and returning to the start is performed when it is not provided with a periodicity and advancing to the next is performed, when it is detected successively for N times (N is an integer equal to or more than 1) (s103), and then it is proceeded to the next step. Then, whether or not identification(ID) information following the synchronizing signal is detected is inspected (s104), and when the ID value is a specified value, the synchronizing signal is defined. Furthermore, by using a window generated at a synchronizing signal position, whether or not the detected synchronizing signal is due to a burst error is inspected (s105).  When the burst error is generated, it is invalidated. returning to the first is performed and detection is started. When it is not due to a burst error, it is recognized as a normal synchronizing signal (s106).

Title: Circuit board
Inventor: TOYODA NAOYUKI
IPC: H05K1/11
Filed: 1996-08-08
Abstract: PROBLEM TO BE SOLVED: To ease the connection of circuit components with a thick conductor of a circuit board through soldering. SOLUTION: A thick conductor 2 which is a metallic plate punched into a specified pattern is adhered to a pattern conductor 4 which is formed by pattern-etching a metallic foil on the surface of an insulation substrate 1. Then a through hole 5 formed on the substrate 1 and a pattern conductor 4 is made larger in diameter than that 3 formed in the conductor 2, thereby making a clearance between the through hole 5 and the conductor 2. When a lead terminal of the circuit components is soldered to the through hole 5, heat of soldering is hard to be released to the conductor 2, permitting easy soldering. Further the outer circumferential part of the conductor 4 in the boundary between the through holes 5 and 3 is covered with a layer made of adhesives so that a solder may not flow toward the conductor 2 when soldering a lead thermal.  Thus it is more effective to provide such a layer made of adhesives.
