Abstract: PROBLEM TO BE SOLVED: To enable discharge machining for many small holes with very small spaces by arranging plural electrode projecting parts at very small spaces, setting a workpiece negative, and specifying a duty factor and a discharge pulse width to perform discharge machining. SOLUTION: A conductive layer 1 is formed on the surface to be worked of a ceramics 3. A lot working electrode 2 is driven by a single power supply, and formed as an electrically integrated frog-like working electrode by the same metal. The ceramic 3 is made negative, and discharge machining is performed with a duty factor ranging from 9 to 25% and with a discharge pulse width ranging from 1 to 8μsec to machine very small holes at very small spaces. If the duty factor is 25% or more, the tip projecting parts of the working electrodes 2 are connected to each other not to machine the workpiece according to the form of the electrode. If the discharge pulse width is 1μsec or less and the duty factor is 9% or less, the ceramic 3 can not be machined.

Title: Game machine
Inventor: UGAWA SHOHACHI
IPC: A63F7/02
Filed: 1999-03-19
Abstract: PROBLEM TO BE SOLVED: To provide a game machine in which the burdens of control relating to the identification information display of a game control means is further reduced and time usable for original game control by the game control means is increased. SOLUTION: A CPU for display control on a display control substrate decides a ready-for-winning state at the time of receiving a command for indicating that the ready-for-winning is attained or losing is defined and the command for specifying left, right and center stop patterns from the game control means of a game control substrate. That is, at the time of receiving the command for specifying the fluctuation period of the pattern from the game control means, a random number of the ready-for-winning is extracted and it is decided to use the ready-for-winning state decided by the fluctuation time specified by the command and the random number. Thus, since the game control means is not required to perform any control relating to ready-for-winning state decision, the loads required for the display control of the game control means are reduced.

Filed: 1996-03-29
Abstract: PROBLEM TO BE SOLVED: To improve the power factor if a capacitor input switching power supply circuit, suppressing its harmonic currents, by widening the conducting angle of its input current. SOLUTION: When a mains witch Q is in ON-state, an energy is stored in the excitation inductance of a primary winding N1 of a main transformer T, and a DC energy is transmitted to the secondary side of the main transformer T. Further, when the main switch Q is in OFF-state, generating a voltage in a clamping wending N3 based on the excitation energy of the main transformer T, a boosting capacitor C3 is charged by this voltage via a diode D7 to generate a charged voltage VC3 in the capacitor C3 . To the side of a power supply rectifier R, the polarity of the character voltage VC3 of the boosting capacitor C3 is opposite to the one of a voltage VC1 of an input capacitor C1 .  Therefore, sine a current flows from the power supply rectifier R even in the term of the rectification output voltage of the power supply rectifier R being lower than the voltage VC1 of the input capacitor C1 , the conducting angle of the input current of a capacitor input type power supply circuit can be widened.

Abstract: PURPOSE:To simplify the equipment while preventing the generation of a false contour by representing the number of kind in the concentration of colors, yellow, magenta and cyan by NY, NM and NC to meet the relationship of NM, NC>NY. CONSTITUTION:Various digital signals from a line memory are converted to a concentration data of YMC with a converter 101 and then, into gamma with a converter 102. A colorless component K as YMC common component is obtained with a ground color removing circuit 103 to be subtracted from the YMC and effect attributed to a turbidity component of an ink is removed with a color correction circuit 104. Then, a voltage signals which are to be outputted to reference tables 105-106 of colors and applied to a head according to the density are outputted to drivers for YMC and black heads in yellow as YU' and YK', in magenta as MU'-MK', in cyan as CU'-CK' and K' as intact respectively. Thus, as many kinds of concentrations are prepared, highly sensitive colors M and C can prevent the generation of a false contour and the simplification of the equipment is possible because of limited kinds of the color Y.

Title: Fire alarm
Inventor: OKADA TOSHITAKA
IPC: G08B17/00
Filed: 1996-03-29
Abstract: PROBLEM TO BE SOLVED: To obtain the fire alarm which is thin and lightweight and makes a fire detecting circuit operate stably and has a low fault rate by providing an alarm and an alarm dummy resistance which is connected between the plus output terminal and minus output terminal of a full-wave rectifying circuit and has the same resistance value with the alarm connected in series with the normally closed contact of a relay. SOLUTION: If a fire takes places, currents flow to the relay 19 and alarm 20, but when a fire is monitored, the current flows to a relay dummy resistance 18 instead of the relay 19 and the current flows to the alarm dummy resistance 21 instead of the alarm 20. The relay 19 and relay dummy resistance 18 are equalized in resistance value and the alarm 20 and alarm dummy resistance 21 are also equalized in resistance value.  Consequently, the main load on the output side of the full-wave rectifying circuit 7 has no variance between the fire time and monitor time and the load circuit voltage on the output side of the full-wave rectifying circuit 7 does not vary, so the operations of the relay 19, alarm 20, etc., become stable and the possibility that a current flows to a constant voltage element 8 is small, so the constant voltage element becomes harder to get out of order, so that the fault rate of the alarm itself decreases.

Inventor: FURUMURA YOSHIYUKI
IPC: B81C1/00
Filed: 1998-03-11
Abstract: PROBLEM TO BE SOLVED: To efficiently measure the accuracy of an etching depth in a noncontact manner by a method wherein a pattern which contains a test pattern is formed on a protective film on the face of a wafer, the pattern is changed into a pattern which can observe a change in proportion to the etching depth in the vertical direction and the remaining etching time required for setting a depth to a prescribed value in an inspection is computed. SOLUTION: The 100 plane crystal is used as a surface, and a test pattern 5 is formed in such a way that its L-shaped side 5a becomes a 111 orientation. In this state, an anisotropic etching operation is performed, and the exposed surface of a silicon chip is etched in a direction perpendicular to the surface of a wafer. The image of the test pattern 5 on the surface of the wafer is inspected under a microscope, and a change which is proportional to an etching depth in the vertical direction can be observed as a length A. Then, in the halfway part of an anisotropic etching process, the image of the test pattern 5 is inspected. On the basis of information on its inspection, the remaining etching time required for setting the etching depth to a prescribed value is computed.  When the image on the surface of the wafer is observed in this manner, the accuracy of the etching depth can be inspected in a noncontact manner, and the measurement of the etching depth can be made efficient.
