Title: Semiconductor integrated circuit chip
Inventor: TAZAKI KATSUHISA
IPC: H01L21/66
Filed: 1990-11-02
Abstract: PURPOSE:To immediately recognize information on production and quality level by a method wherein a control information application region other than an inner function region or the like is provided on a main surface of a semiconductor substrate. CONSTITUTION:A semiconductor integrated circuit chip 1 comprises an inner circuit function region 2, an input/output buffer region 3, a bonding pad region 4, and a control information application region 5 of production information, quality level information or the like. This control information application region 5 is completely insulated from the circuit function region 2d and the input/output buffer region, and after a physical and machine application, the region 5 does not give an influence on an operational function of the semiconductor integrated circuit chip itself. Thus, only 2-stage control such as 'good' and 'inferiority' can conventionally be carried out, however in this embodiment, several stages are separated, and control of the finest wafer or a chip unit can be carried out.

Title: Method and device for gas turbine combustion
Inventor: BANDAI SHIGEMI
IPC: F23R3/00
Filed: 1987-11-27
Abstract: PURPOSE:To maintain the differential pressure of fuels at an optimum level to perform a stable combustion by supplying either part of main fuel or fluid other than fuel such as air, nitrogen, steam, etc., to at least either one of pilot fuel and main fuel in proportion to the amount of fuel. CONSTITUTION:An auxiliary line 10 is provided as a branch of a main fuel pipe 4, and, at the end of the auxiliary line, an auxiliary nozzle 10 is provided as a pilot fuel nozzle.

Filed: 1998-10-05
Abstract: PROBLEM TO BE SOLVED: To provide a wire cutting electric discharge machining method capable of enhancing the accuracy of profile processing substantially when an out-corner is processed in a second cutting process. SOLUTION: When a second cutting process is carried out for the side surface of the corner part of a work piece 16 while let pulsive electric discharge be intermittently applied between the work piece W and a wire electrode 2 supported by a wire guide 4 to be relatively moved with respect to the work piece along a relative moving route (off-set locus) 54, just before processing by means of the wire electrode 2, arrives at the corner point 16A of a corner part 16, and the advancing direction of the wire guide 4 is directed to the oblique escaping direction so as to allow the wire guide 4 to be parted from one processing surface while the corner point 16A is being held in between.  Subsequently, after the wire electrode 2 has passed its target corner point, the advancing direction of the wire guide 4 is directed toward the oblique approaching direction so as to allow the wire guide 4 to be approached to the other processing side surface, so that let the wire electrode 2 be thereby returned to the original off-set locus 54. By this constitution, when the out-corner is processed at the time of second processing, the accuracy of profile processing can thereby enhanced substantially.

IPC: H01F7/18
Filed: 1986-12-16
Abstract: PURPOSE:To make the making current of a contact point of a change-over switch nearly equal to zero, and prevent contact point transfer of the change- over switch, by connecting in series the change-over switch, a second resistor, and the light emitting diode of a photocoupler, between the DC output terminals of a full-wave rectifier, and connecting the phototriac of a photocoupler in parallel with a first condenser and a first resistor. CONSTITUTION:A change-over switch 8, which acts linking to the operation of a moving-iron core 10, opens just before the moving-iron core in attracted to the fixed-iron core, and cuts off a current flowing toward a light emitting diode 13.

The current flowing through the change-over switch 8 is limited by the resistor 11, and the contact cut-off current at the time of opening instance of the change-over switch 9 is very small. The change-over switch 8 closes after the energy of a electromagnetic coil 2 is discharged by a flywheel circuit composed of a full-wave rectifier 1 and a transistor 3, so that the current becomes nearly equal to zero, and contact point transfer of the change-over switch can be prevented.

Title: Portable electronic device and method for checking its memory
Inventor: KURIYAMA RYOICHI
IPC: G06F12/16
Filed: 1988-11-25
Abstract: PURPOSE:To shorten check time by writing optional data generated by a data generating means and data obtained by inverting the bits of the optional data in the whole space of a memory part and discriminating whether a memory part is normal or not based upon respective results of 1st and 2nd check means for checking whether writing is normally executed or not. CONSTITUTION:An optional data (a character) is inputted from the external and written in the memory part 12 to verify it. A data obtained by inverting the bit of the optional data is inputted from the external and written in the memory part 12 to verify it. When the data is not normally written as the checked result, a control element 11 outputs status meaning memory abnormality to a terminal equipment. Although 256 writing/verifying operations are required for checking one byte in an ordinary method, the memory part 12 can be checked by two writing/verifying operations in this method. Consequently, the check time can be shortened and load for the number of times of guarantee of the memory part 12 can be reduced.

Title: D/a converter
Inventor: NAKAMURA YASUYUKI
IPC: H03M1/10
Filed: 1987-11-25
Abstract: PURPOSE:To obtain a D/A converter with high linearity by correcting the fluctuation of a bias condition of a control element constituting a D/A conversion section depending on an inputted digital quantity. CONSTITUTION:If a 1st output current outputted to a 1st output terminal 3 is changed in response to a digital quantity inputted to a D/A conversion section 1, the potential of the 1st output terminal 3 is changed. Thus, the bias condition of the control element connected to the 1st output terminal 3 in control elements being components of the D/A conversion section 1 is changed to change a current flowing to the control elements. In such a case, a 2nd output current supplied to a 2nd output terminal 4 changes in an opposite direction to the 1st output current in a direction to compensate the current changed flowing to the control element connected to the 1st output terminal 3. Thus, the deterioration in the linearity of the output of D/A converter is prevented.
