Title: Methode d'acces a une memoire de micro-ordinateur
Inventor: UMEKI TSUNENORI
IPC: G06F12/02
Filed: 1992-01-08
Abstract: The following measures are taken to obtain a microcomputer which securely fetches an instruction code from a low-speed memory to improve the reliability when the instruction code is not present in an instruction queue buffer.  When the requested instruction code is not present in the instruction queue buffer, a CPU judges whether the memory to be accessed is a high-speed memory or low-speed memory.  When the memory to be accessed is a high-speed memory, the CPU fetches the instruction code directly from the memory by skipping the instruction queue buffer.          Meanwhile, when the memory to be accessed is a low-speed memory, the CPU does not skip the instruction queue buffer but it waits for the instruction code to be fetched to the instruction queue buffer.  Thus, the instruction code is securely fetched, the reliability is improved, and the timing is easily set for design.

Patent CA-2062944-A1 (CA)
Title: Method and apparatus for non-destructive testing
Inventor: HARRISON DAVID J
IPC: G01N27/90
Filed: 1990-07-13
Abstract: Eddy current based method and apparatus uses a repetitive square wave signal applied to an excitation coil and operates in a pulse echo mode by gating the detected field signal at synchronised intervals to generate one or more sequences of like gated slices obtained from respective detector positions on a circular scan path.  Suitable time gating to exclude surface and near-sur-face reflections overcomes surface clutter and flaws are detected by examination of the sequence of slices for characteristic changes in level. Both method and apparatus have special application for crack investigation at rivet fasteners or similar, e.g. in airframes, and have ability to cope with ferrous fasteners in non-ferrous material. Excitation coil and magnetic detector are com-bined in a probe and the latter is driven around a circular scan path. A  centring display is derived by examination of the near-sur-face reflection signal to determine the position and level of the peak slice level on the scan path sequence of slices.

Title: Cell-cycle-dependent regulation of phosphorylation of the human retinoblastoma gene product
Inventor: FUNG YUEN K
IPC: C12Q1/22
Filed: 1990-12-07
Abstract: In the field of regulation of cell proliferation, a method of inhibiting or preventing cell proliferation is disclosed. Rb, a stable protein encoded by the retinoblastoma gene (RB1), is synthesized at all phases of the cell cycle. Newly synthesized Rb is underphosphorylated during the G0 and G1 phases but is phosphorylated at multiple sites at the G1/S boundary and during S phase.  HL-60 cells lose their ability to multiply phosphorylate newly synthesized Rb when induced to terminally differentiate by chemicals such as dimethylsulfoxide, retinoic acid and butyric acid. A  method of using these chemicals to inhibit or prevent cell proliferation in cells containing Rb is disclosed.

Abstract: ABSTRACT      Rail learning is combined with feedback in a control for improving ride quality in an elevator.  For example, a pre-stored signal indicative of a horizontal deviation of the rail's surface from a vertical reference is retrieved and used along with a sensed signal indicative of a horizontal position (or other parameter indicative of a disturbance of the elevator) relative to the rail's surface (or a reference) for controlling an actuable horizontal suspension for reducing horizontal disturban-ces of the elevator while guiding an elevator vertically in a hoistway along a rail.  As another example, a sensed force signal is averaged over a plurality of trips under differing load conditions and the average is pre-stored for retrieval at various vertical points in the hoistway and may be used, in combination with a feedback loop, to predict horizontal forces about to act on the car.
