Title: Dynamic random access memory
Inventor: KUROKI OSAMU
IPC: G11C11/406
Filed: 1999-11-18
Abstract: PROBLEM TO BE SOLVED: To provide a dynamic random access memory(DRAM), capable of controlling the cycle of self-refresh operation. SOLUTION: When a monitor trigger signal MON is applied from the outside in addition to a self-refresh signal SRF from a timing generator 12, a self-refresh timer circuit 100 generates an internal timing signal TIM in a fixed cycle with a ring oscillation circuit provided therein and outputs a monitor output signal MOT corresponding to the first cycle of this internal timing signal TIM. The monitor output signal MOT is passed through an output circuit 200 and outputted from an output electrode as an output signal OUT for measurement. The ring oscillation circuit inside the self-refresh timer circuit 100 has an inversion amplifier capable of increasing/decreasing delay times by cutting a fuse and in a wafer check process, the cycle of the internal timing signal TIM can be controlled suitably, on the basis of the measured result of the output signal OUT.

Title: Improved sintering method for thin film manufacturing of calcium phosphate material
Inventor: SHIDONII EMU PIYUU
IPC: C03C17/25
Filed: 1995-12-18
Abstract: PROBLEM TO BE SOLVED: To make it possible to form a thin film of a calcium phosphate material on a base layer in order to support osteocyte activity by selecting a sintering temp. from a prescribed range where the range of a ratio of hydroxyapatite to αtricalcium phosphate is the prescribed range. SOLUTION: The method of forming the thin film of the calcium phosphate material on the base layer in order to support the osteocyte activity thereon is executed by sintering the film at the temp. selected from the temp. range where the compsn. of the calcium phosphate material in the film is optimized and converting the hydroxyapatite to the α tricalcium phosphate in a sintering stage. At this time, the degree of such conversion is dependent upon temp. The optimized compsn. is 50:50 to 20:80 in the ratio of the hydroxyapatite to the α tricalcium phosphate. The sintering temp. is selected from a range of 920 to 1100 deg.C. At this time, the conversion rate is approximated more to the upper limit ratio 20:80 as the sintering temp. is higher.

Title: Measuring method for state of road surface
Inventor: IMOTO HARUO
IPC: G01B21/00
Filed: 1995-12-18
Abstract: PROBLEM TO BE SOLVED: To obtain a measuring method in which the analytical operation of a crack on a road surface is made efficient by recording distance data on one recording medium together with image data. SOLUTION: An area shutter camera 1 photographs the state of a crack on a road surface, and it outputs image data. In addition, a range finder 2 acquires running distance data on a measuring vehicle so as to be output, and the running distance data is added 3 to the frame signal of an image signal so as to be recorded on a video tape 5 by a video deck 4. When the crack on the road surface is analyzed, the video tape 5 on which the data is recorded is read out by the deck 4, an image signal which contains the running distance data is sent to a distance-data separation device 6, and only the running distance data is separated form the image signal by using the device 6.  By making use of the data, the overlap amount of the image frame of image data on every road surface is computed so as to be excluded, and it is analyzed as the image of the continuous state of the crack on the road surface. In this manner, since the running distance data is recorded on one recording medium together with the image data on the road surface, an analytical operation such as a data processing operation, a retrieval operation or the like can be made efficient.

Title: Vibrational angular velocity meter
Inventor: FUJIO HISAMITSU
IPC: G01C19/56
Filed: 1993-12-27
Abstract: PURPOSE:To realize compact size and low cost by constituting a vibrator of a plurality of beam type vibrators formed within the same plane, supporting one side of the vibrator on a substrate and further supporting a weight on the other side of the vibrator. CONSTITUTION:A silicon vibration weight 4 is fixed to a silicon substrate 1 with four silicon vibrator beams 2. When AC voltage near the resonance frequency of a vibrator is applied to a driving voltage and electrostrictive thin film 4, a natural vibration is excited on the vibrator, due to a piezoelectric inverse effect. At this stage, when the beams 2 begin to rotate about a shaft, a Coriolis' force Fc expressed as Fc=2m[V.OMEGA] is generated in both axial and vibrational directions of the beams 2, where (m) stands for the mass of the vibrator, V for vibrational speed and OMEGA for rotational angular velocity. Strain occurring in the beams 2 is detected as a piezoelectric signal via a detecting piezoelectric and electrostrictive thin film 6. As a result, the rotational angular velcoty Q around two shafts orthogonal with each other can be detected with a single element.
