IPC: H04N5/66
Filed: 1989-09-22
Abstract: PURPOSE:To light a discharge lamp as the light source or the back light of a video device in the stable state free from beat and flicker by controlling the switching of a DC-AC inverter by a pulse signal obtained by dividing the frequency of a horizontal synchronizing signal. CONSTITUTION:The frequency of a horizontal synchronizing signal fM of the NTSC video signal is divided by a frequency divider PS, and switching of a DC-AC inverter IV is driven by the output pulse signal of the frequency divider PS. That is, switching of the DC-AC inverter IV is controlled by the pulse signal which is outputted from the frequency divider PS and has the frequency synchronized with the horizontal synchronizing signal, and an AC voltage having the frequency synchronized with the horizontal synchronizing signal is generated and is supplied to a discharge lamp La. Consequently, the driving AC power to the discharge lamp La has the frequency synchronized with the video signal, and the frequency is stabilized as the signal source for driving of the DC-AC inverter IV. Thus, the discharge lamp La as the light source or the back light of the video device is stably lit without beat and flicker.

Title: Method for testing semiconductor integrated circuit device
Inventor: OZEKI MASANORI
IPC: H01L27/04
Filed: 1996-09-19
Abstract: PROBLEM TO BE SOLVED: To make it possible to narrow a defect occurring spot within a certain extent of area when the occurrence of a defect is detected in a semiconductor chip by changing the data of an arbitrary number of FFs and comparing the variable data of the measured value of a quiescent internal standby current (IDDQ). SOLUTION: A plurality of FFs, (F/Fs) l-3 constituting a scanner chain 4 is connected to an internal circuit 5. Then an IDDQ measuring environment is set so that no DC path is formed between a power source VDD and the ground by impressing 'L' upon netA by using an external signal. When the occurrence of a defect is detected in a semiconductor chip during IDDQ measurement, the set state of the arbitrary number of F/Fs is successively changed. Then the occurring spot of the defect is estimated from the data obtained when IDDQ measured values change and when the data do not change. Thus not only the defect can be discriminated, but also the occurring spot of the defect can be estimated without using any optical means.

Title: Magnetic bubble memory element
Inventor: SATO YOSHIO
IPC: G11C19/08
Filed: 1986-10-20
Abstract: PURPOSE:To impart an additional degree of margin in terms of positioning in a joint part by forming a recessed part on the joint part between the bar patterns of an ion implantation transfer path in order to specify width in an opening. CONSTITUTION:The recessed part (cusp) 15 where width in its opening 15 is less than twice the diameter of a bubble is formed on the joint part between the bar patterns 14 of the ion implantation transfer path 10. Thus the bar patterns 14 cover the bottom of the cusp 15 and its vicinity on an end part that bubbles pass by. However, the other end is away from a boundary 13 partitioning an ion implantation area 12 and an ion nonimplantation area. Thus even if the bar patterns 14 shift farther to the ion implantation area 12, the number of bubbles moving along the bar patterns 14 decreases to improve a passing margin. Hence the margin degree in terms of positioning areas to set values can be improved.
