Title: Semiconductor wafer, semiconductor chip and dicing method therefor
Inventor: SAKAZUME TATSUMI
IPC: H01L21/301
Filed: 1993-03-19
Abstract: PURPOSE:To prevent damage of an element by dicing by so providing deeper grooves than a depth of the element as to be disposed along a cut zone at both sides of the zone of a semiconductor wafer. CONSTITUTION:A semiconductor wafer 10 is provided with grooves 12 along a cut zone 11 at both sides of the zone 11. The grooves 12 are formed deeper than an element 5. Dicing is conducted along a center of a cut zone 11 by a blade 14 attached to a spindle 15. The blade 14 is first brought into contact with a surface of the wafer 10, and then moved in a depth direction to be cut. In this case, a crack 4 is generated at a cutting end, and extended in the depth direction or a lateral direction. When the crack 4 reaches the grooves 12 at both sides of the zone 11 of the wafer 10, an end of the crack 4 is formed in a space region, and hence the extension is discontinued to prevent it from invading to an element. Thus, a malfunction is reduced to improve its yield.

Title: Receiver and its method
Inventor: TAKABAYASHI KAZUHIKO
IPC: H04L12/54
Filed: 1999-03-08
Abstract: PROBLEM TO BE SOLVED: To allow a user to operate in time series contents broadcast and distributed as continuous data. SOLUTION: Contents are fragmented in a meaningful structure unit and meta information relating to fragment data is added to the fragment data and the resulting fragment data are distributed (A). The meta information is attribute information of the fragment data and consists of a positioning of the fragment data in a contents structure, a temporal arrangement and a unique ID or the like. A receiver stores the fragment data and corresponding meta information in cross reference with each other (B). The fragment data with the same ID cannot be stored on the meta information. Each of the fragment data can be controlled for the reproduction. In the case of reproducing the fragment data in parallel with the reception of contents, repetitive reproduction of the desired fragment data of the user and the temporal stop of reproduction are attained (C).  After the distribution of the contents, the sequence of the stored fragment data is revised according to the desire of the user and reproduced (D).

Title: Motor-driven power steering device
Inventor: TAKEUCHI KANJI
IPC: B62D5/04
Filed: 1995-03-20
Abstract: PURPOSE: To simplify the constitution in an interface part between a microcomputer and a torque servo system composed of an analog circuit. CONSTITUTION: Motor assist control is performed by a torque servo system reaching an electric current detecting part 9 from a phase compensating filter 2 on the basis of a steering torque signal from a torque sensor 1. A microcomputer 20 outputs a first pulse signal of the duty ratio to show a restoration compensating value to a neutral steering angle and a second pulse signal of the duty ratio to show car speed sensitive gain. In the torque servo system, an adding operation part 3 performs processing to add the restoration compensating value by the duty ratio of the first pulse signal to the steering torque signal, and a multiplying operation part 5 performs processing to multiply an assist torque signal by the car speed sensitive gain by the duty ratio of the second pulse signal. In this way, since a PWM signal is used, the constitution in its interface part can be simplified.

Title: Method for detecting stop position of, and control equipment for drive of, brushless motor
Inventor: YAMAMOTO KIYOSHI
IPC: H02P6/20
Filed: 1994-03-30
Abstract: PURPOSE:To make it possible to smoothly start a brushless motor without rotor vibration or reversing in a short time, and to miniaturize the motor, by detecting the stop position of rotor rotation by a static method without use of any sensor element. CONSTITUTION:When a diagnostic signal T of a frequency higher than that of exciting signal at start-up is applied between winding U and winding V, a rotor does not rotate but induced voltage signal S due to mutual induction is observed in winding W. The induced signal S reflects the magnetic resistance (mutual inductance M) determined according to the area (number of magnetic poles) and polarity of the magnetic pole of the rotor to which the winding W is opposed depending on the stop position of rotor rotation. The phase and level (voltage) of the induced signal S are periodically varied. Thus the stop position of rotor rotation (excited phase) can be identified by detecting the induced signal S, its phase, voltage and the like.

Title: Method for regulating composition of molten pig iron
Inventor: UNO SHIGENORI
IPC: C21C1/08
Filed: 1985-03-27
Abstract: PURPOSE:To improve the addition yield of an Si additive as well as to simply prevent a drop in the temp. of molten pig iron at a low cost by simultaneously adding the Si additive and a combustion material to the molten pig iron. CONSTITUTION:When an Si additive such as Fe-Si is added to molten pig iron, the Si additive and a combustion material are simultaneously added. A material having higher oxidizability and combustibility than Fe-Si, e.g., C, Ti, Mg, sawdust or coke breeze is used as the combustion material. Before the Si additive is oxidized during addition, the combustion material burns and forms a nonoxidizing atmosphere, so the Si additive is added without oxidizing Si. The temp. of the molten pig iron is increased by the heat of combustion of the combustion material. Thus, the addition yield of the Si additive is stably improved.

Title: Formation of phosphor pattern
Inventor: TANAKA TATSUO
IPC: H01J9/227
Filed: 1980-05-07
Abstract: PURPOSE:To obtain a strikingly clear phosphor pattern by evenly applying a phosphor powder to a photosensitive film exposed into a given pattern, before the film is subjected to development. CONSTITUTION:Three different original color stripes R, G and B are formed on a glass panel GL of an index tube, with black stripes BS interposed between them. At the same time, each group consisting of three stripes R, G and B is covered with a metal backing MB. A photosensitive film PC is evenly applied to the metal backing MB, before the film PC is exposed to an ultraviolet ray VL or the like by using a mask MK which is provided with a given index pattern. Thus treated undeveloped photosensitive film PC is evenly coated with a water-containing phosphor powder FP which is usually used for an index stripe. Following that, developing treatment is performed on the film PC coated with the power FP. As a result, phosphor powder applied to parts of the film PC which are exposed and hardened remains, and that applied to the other parts of the film PC is washed and removed. Consequently, the outline of the phosphor pattern is made extremely clear.
