IPC: H01L21/66
Filed: 1990-08-06
Abstract: PURPOSE:To perform a performance test at high speed by discriminating it at the time of actual operation or performance test according to the state of a test signal, and at the time of the performance test, raising the extent of responsiveness or selecting it to such a circuit as high in the responsiveness. CONSTITUTION:A voltage comparator 102 compares two voltages generated at a circuit A101, feeding a circuit B103 with the result. This comparator 102 is driven by a bias current 104 at time of usual operation.

Title: Method for assembling embedded dram device and the embedded dram device having dual gate cmos structure
Inventor: RIN EISHO
IPC: H01L27/10
Filed: 1998-07-23
Abstract: PROBLEM TO BE SOLVED: To prevent a shallow PN junction between a source/drain region and a substrate from being made still thinner by a self-aligned silicide process. SOLUTION: An SEG process is carried out for forming plural amorphous silicon layers on polycrystalline silicon for various FETs and source/drain regions. A self-aligned silicide process is carried out on the layers to form titanium silicide layers 344, 346, 348 and 350, and the titanium silicide layers 344, 346, 348 and 350 are spaced from the substrate by source/drain regions. Since the formation of the titanium silicide layers 344, 346, 348 and 350 does not deplete the silicon atoms part of a substrate 300, shallow junctions causing leakage current in a DRAM device are prevented from being still thinner.  In the case of a dual gate complementary metal oxide semiconductor(CMOS) structure, since the silicide layers are formed after the activation of impurities in the source/drain regions generation of mutual diffusion effect between an N-type polycrystalline silicon layer and a P-type polycrystal silicon layer can be prevented.

Title: Tilt servo device
Inventor: SUGIMOTO KAZUHIKO
IPC: G11B7/09
Filed: 1989-08-11
Abstract: PURPOSE:To reduce the level of the offset deviation of tilt servo to the one without generating a trouble in practical use by automatically performing the switching of tilt offset corresponding to a plane confronting with a pickup. CONSTITUTION:The opening/closing of a switch 43 is controlled with the output of a motor rotational direction detection circuit 44 which performs the detection of a spindle motor 33 rotating a disk optically or magnetically in a rotational direction, and the pickup 2 reproduces the lower plane of the disk. When the spindle motor 33 is rotated in a forward direction, an open state where L output is issued from the motor rotational direction detection circuit 44 is set. Adversely, when the upper plane of the disk is reproduced and the spindle motor 33 is rotated in a backward direction, a closed state where H output is issued from the motor rotational direction detection circuit 44 is set. In such a way, the offset deviation in the tilt servo can be reduced to the level without generating the trouble in practical use.

IPC: B23K9/12
Filed: 1987-08-24
Abstract: PURPOSE:To perform the satisfactory welding by detecting an inclination of a weld zone by an inclination detection means and holding the weld zone of a work horizontally by a work supporting means based on its result to hold the weld zone of the work at a prescribed angle with a welding torch at all times. CONSTITUTION:The work 5 is positioned and fitted on a positioner 6 and the welding torch 2 is positioned with respect to the weld zone of the work 5. While the welding torch 2 is moved in the longitudinal direction of the weld zone, a travelling carriage 1 is brought into contact with the vicinity of the weld zone of the work 5 to detect the inclination of the weld zone of the work 5. Based on this detected result of the inclination, the positioner 6 is controlled to control the inclination of the work 5 continuously so that the weld zone is always held horizontally. By this method, the continuous welding is performed while the welding torch 2 is held at the prescribed angle and the quality of the weld zone can be improved.

IPC: A61B5/04
Filed: 1998-07-23
Abstract: PROBLEM TO BE SOLVED: To provide a biological signal telemetry instrument capable of precisely receiving a signal from plural transmitters by one receiver. SOLUTION: Frequency of data transmitted from plural transmitters are all made nearly equal and an ID signal for confirming from which transmitter data is transmitted is incorporated in this data. Then, this data is transmitted plural times in a prescribed period. In addition, transmission interval between data transmission of a first time and that of a second time in each of the plural transmitters is set to become winder in order and at the time of comparing transmission intervals which are adjacent to each other in their sizes, the transmission interval of the transmitter of a longer transmission interval is set to be longer than a length obtained by adding a time for transmitting data twice to the transmission interval of a transmitter of a shorter transmission interval. Thus, whichever data among plural data may interfere, the interference of other data is prevented.

Title: Magneto-optical recording and reproducing device
Inventor: FUJINAGA TERUAKI
IPC: G11B11/105
Filed: 1989-08-10
Abstract: PURPOSE:To obtain good regenerative signal quality against surface rocking of a magneto-optical recording medium by making the direction of an incident plane of inclined incident light approximately orthogonal to a recording track of the magneto-optical recording medium. CONSTITUTION:An in-plane magnetization film to be magnetized in the in-plane direction is used for a magneto-optical disk 1, and at the time of reproducing information, linearly polarized light generated from a semiconductor laser 3 irradiates a required part of the in-plane magnetization film of the magneto- optical disk 1 via a condenser lens 4, a shaping prism 5 and an objective lens 6. In this case, since the incident plane of the inclined incident light is orientated approximately in the orthogonal direction to the lengthwise direction of the recording track, even when the surface locking happens to the magneto-optical disk 1, a dislocation of a condensing position is replaced with a track shift. Consequently, this dislocation is compensated by performing a track servo, etc. By this method, the good regenerative signal against the surface locking is obtained.

Title: Formation of resist pattern
Inventor: NAKAMURA HIROYUKI
IPC: H05K3/00
Filed: 1990-08-08
Abstract: PURPOSE:To make it possible to reduce the number of times to detect alignment marks and hence enhance throughput by recognizing even a large pattern as a set of finely divided patterns and directly drawing said pattern based on line exposure. CONSTITUTION:When finely divided patterns and a large pattern coexist, only a fine beam whose beam diameter is throttled, is adopted. The fine pattern is recognized as a single line while the large pattern is recognized as a set of the finely divided patterns. They are not separated into several types of patterns based on the size of lithography patterns but handled as a single type of lithography pattern data for simplification. For example, a lithography pattern 14 is prepared to write a gate pattern 11, using an electron beam. A pad section 12 is arranged to be zigzag line data, which is prepared by the same data to the line data of a gate pattern. It is, therefore, possible to finish an electron beam lithography process at one time.
