Inventor: IWATA JUN
IPC: G06F11/32
Filed: 1991-03-11
Abstract: Abstract of the Disclosure:         In a display control apparatus for controlling a display unit for displaying operation performance of an arithmetic processor with reference to a performance signal representative of the operation performance, a first producing circuit (28) produces a peak signal in compliance with a count signal produced by a counting circuit (22) which is for counting an operation number of operation of the arithmetic processor.  A comparing circuit (31) carries out comparison between the peak and the performance signals to produce a result signal representative of a result of the comparison.  A second producing circuit (29) produces the performance signal with reference to the result signal.

Abstract: APPARATUS AND METHOD FOR DETECTING THE POWER LEVEL    IN SINGLE AND MULTI-STRIPE INTEGRATED LASERS                         ABSTRACT OF THE DISCLOSURE The purpose of the present invention is to provide an apparatus for detection of a laser output on a semiconductor wafer, especially where the laser and detector are formed by similar or simultaneous processes on the same substrate. A laser cavity and a detection cavity are formed on a semiconductor wafer. The two are formed in parallel such that each has a generally axial orientation. Light emitted laterally from the laser cavity is detected by the detection cavity. The amount of light detected can then be transformed into data, which in turn can be used to control the output of the laser. Advantages of the present invention include the ability to simultaneously form the laser and detector portions, the detector portion so formed does not interfere with the beam being provided by the laser, and the ability to integrate multiple laser-sensor pairs in a semiconductor device.

Title: Rock drill
Inventor: RUMPP GERHARD
IPC: E21B10/44
Filed: 1991-04-09
Abstract: A rock drill has an axially extending shank (1) with a drill head (2) on one end.  The drill head (2) has an end face (3) with a cutting blade (4) and cutting pins (5)  extending outwardly from the and face in the drilling direction.   The cutting blade (4) extends, diametrically across the end face and projects radially outwardly from the drill head (2) said axially outwardly from the end face (3).   The cutting pins  (5)  are arranged on a diameter of the drill head which forms an acute angle relative to the cutting blade (4).  Due to the acute angle between the cutting pins and the diametrically arranged cutting blade, removal grooves extending axially from the end face can be enlarged.
Patent CA-2044397-A1 (CA)
Inventor: OSTAPCHENKO GEORGE J
IPC: A61L27/56
Filed: 1991-06-12
Abstract: ABSTRACT OF THE DISCLOSURE A process for producing an article of a synthetic resin material or a thermoplastic resin blend having a microcellular structure comprises dispersing in  a solid thermoplastic resin matrix having hydrophilic functional groups a finely divided water-soluble material, shaping the resin matrix containing the water-soluble material into the desired article, and immersing the shaped article in water at suitable temperature to cause the resin matrix to well to an extent of at least about 50% by volume while wet.  The immersion causes water to diffuse into the resin matrix and solvate the water-soluble material, which becomes encased in water-filled cells that have solid walls, are substantially closed, and do not form an interconnecting porous network.          Articles made by this process include, among others, vascular grafts and organoids.

Title: Transmission chain structure
Inventor: TUOMIKOSKI PEKKA
IPC: F16G13/02
Filed: 1991-10-02
Abstract: The invention relates to chain structure comprising several form pieces (1) and a wheel arrangement comprising at least one drive wheel (7) for transferring the chain, which is formed of said form pieces (1). The bearing surface (1B) of each form piece (1) consists of at least one transverse opening (2) which is arranged to be situated near one of the articulations (4, 5), which opening consists of the contact edge, the bottom and the back edge. When the chain is in mesh said openings (2) of the chain co-operate with the transverse joint pins (9) belonging to said drive wheels (7). The free length of the joint pins (9) essentially correspond to the width of the form pieces (1), whereupon the contact area formed during the contact situation in said mesh of said pins (9) and the openings (2) essentially corresponds in length to the width of the form pieces (1). After said contact situation said pin (9) leaves the opening (2) of the chain from that end thereof which is on the side of the trailing edge. In said contact situation and seen from a direction perpendicular to the largest axial cross-sectional area of pin (9), the free area of said opening (2) is essentially larger than the cross-sectional area of the correspond-ing pin (9), whereupon said contact area is formed on that part of the contact edge of the opening (2) on the bearing surface (1B) which joins said bottom. Furthermore, the largest distance of said contact edge from the centre line (K), which goes through the centres of the holes at the ends of the form piece (1), is essen-tially larger than the corresponding distance of said trailing edge from said centre line (K).
