Abstract: PURPOSE: To increase the fidelity of the disk reproduction and thus to obtain a high-performance head shell by giving the casting connection to both the main body and the holder via the nonoxide-group ceramics featuring the light weight and high rigidity.  
     CONSTITUTION: The nonoxide-group ceramics such as the silicon nitride, silicon carbide or the like which features the light weight, high rigidity and intensity plus the excellent heat impact properties each is used for the material of ceramic substrate 1. And the aluminum alloy, magnesium alloy and the like is used for the metal material of terminal holder 2. Holder 2 is then connected to one end of substrate 1 through the casting method. Thus the harmful vibration can be reduced extremely to enhance the reproduction at the middle and low sound ranges, and also the casting via the diecast or the like. As a result, a shell form of the L-shaped cross section can be obtained with a high measurement accuracy and flatness.

Filed: 1987-06-30
Abstract: PURPOSE:To precisely form an image on a specified position by detecting the position of a register mark in the midst of forming the image and correcting the position of the image on an image carrier in the midst of forming the image based on the detection signal. CONSTITUTION:The image 33 is formed on a belt 8 and the crossed register marks 16 and 17 are continuously formed out of an image area (on both sides of the image 33) in a moving direction of the belt (simultaneously with the image) in an electrophotography method, then the belt 8 proceeds in a direction shown with an arrow 11. Pickup elements 14 and 15 pick up the marks 16 and 17 in a timing when the register marks 16 and 17 primarily pass pickup points 14a and 15a (fixed) based on the sequence signal from a sequence controller. When the arrival of the marks 16 and 17 at the pickup points is later than an ideal timing, the quantity of delay is detected from a mark pickup signal in the timing when the marks primarily pass. Based on the quantity of the delay, the phase of a DELAY(CV) signal is made to proceed and the timing of a vertical synchronizing signal is advanced by reducing the value of the margin register. The slurring of color can be corrected.

IPC: G11C11/413
Filed: 1997-06-18
Abstract: PROBLEM TO BE SOLVED: To make it possible to provide the semiconductor memory device, which is operated stably even when a power supply voltage is less than 1 V, by increasing the potentials of a power supply line and a word line to a perfect CMOS type memory cell at the time of reading. SOLUTION: On a main substrate P<-> of a semiconductor, an N well N<-> is formed. Furthermore, P<+> diffused regions P11 and P12 and P21 and P22 of P-type transistors P1 and P2 and a potential fixing N<+> diffused region N30 furthermore are formed. A power supply line VM to a memory cell is connected to only the P<+> diffused regions P11 and P21. A power supply VDD is connected to the N<+> diffused region N30. Thus, a pn connecting diode is formed in the forward direction from the P<+> diffused regions P11 and P21 to an N well N<-> . In the region where the power supply voltage is less than 1 V, the increasing voltage to the degree of a threshold value for activating the diode is not required. There is no leakage to the N well N<-> . By separating the power supply line VM from the N well N<-> in this way, the capacity, which is added to the power supply line of a non-boosting line, can be decreased, and the voltage increasing efficiency can be improved.

Filed: 1992-05-29
Abstract: PURPOSE:To suppress degrading in quality of picture of a tomographic image by applying an inclined magnetic field in the direction of encoding the phase of a pattern in such a manner that the intensity of a phase offset inclined mag netic field does not change at a DC part and near the DC part. CONSTITUTION:The intensity of an inclined magnetic field in the direction of encoding the phase and that of a phase offset inclined magnetic field which is applied immediately before a signal reading inclined magnetic field to be applied in the direction of encoding the frequency are determined to a specified value, respectively, by an inclined magnetic field generation system 3. Then, the inclined magnetic field in the direction of encoding the phase of a pattern is applied in such a manner that the intensity of the phase offset inclined magnetic field does not change at the DC part on an original data space (space K) of an echo signal to be measured and at a low frequency area near the DC part. As a result, an area is photographed other than the DC part on the space K and the low-frequency area near the DC part. This constitution enables the suppression of degrading in quality of picture as caused by a large change in the intensity of the inclined magnetic field in the direction of encoding the phase.
