Title: A/d converter
Inventor: NAKANO YOSHITAKA
IPC: H03M1/12
Filed: 1991-05-28
Abstract: PURPOSE:To quicken the operating speed of the A/D converter by devising the A/D converter such that a digital signal whose speed is twice the speed of each A/D converter circuit. CONSTITUTION:An analog signal (a) inputted to an A/D converter circuit (1)2 is converted by using a sampling clock (b) from an input terminal 4 into a digital signal (d). On the other hand, the analog signal (a) inputted to an A/D converter circuit (2)3 is converted by using an inverted sampling clock (c) into a digital signal (e). The digital signals d, e are inputted to a multiplexer circuit 5, in which they are subjected to time division multiplex. Since the multiplexed digital signal (f) has two sampling values for one sampling period, the signal is digitized at a double speed.

Title: Toner manufacturing method
Inventor: ABE TSUGIO
IPC: G03G9/09
Filed: 1996-05-16
Abstract: PROBLEM TO BE SOLVED: To provide a toner manufacturing method, by which a cohesive, matter and coarse grain are stably removed over a long period of time and the cohesive matter is hard to be generated to a filling process by mixing coloring particles with a specified weight average particle diameter and an external additive, and then processing the above mixture by a sieve of a twill woven net satisfying specified conditions. SOLUTION: After coloring particles with a weight average particle diameter (Dt) of 3-15u are mixed with an external additive, the mixture is processed by a sieve of a twill weave net satisfying conditions expressed by the equation 2Dt<w[μm]<35Dt. In the equation, w represents a spacing of a sieve. The average diameter d of a wire 1 is preferably 34-45μm, and the average opening of the net is preferably 40-65μm. The twill net of the sieve has a structure in which rectangular meshes are combined to form a square opening 3, so that toner can be easily passed without change of external adding state of the external additive. Accordingly, it is possible to obtain toner which is excellent in productivity, has good durability of net of the sieve, and is excellent in characteristics.

Title: Trimming of conductor pattern
Inventor: ICHIDA FUMIHIRO
IPC: H01C17/22
Filed: 1989-05-17
Abstract: PURPOSE:To obtain an integrated circuit having high reliability concerning a circuit function without damaging the substrate surface by a method wherein, when material of a part of a conductor pattern on a substrate is eliminated, spark discharge energy accompanying discharging current flowing only between the conductor pattern and a discharging electrode is used. CONSTITUTION:A conductor pattern 2 having an object part position 5 to be subjected to trimming is formed on an insulating substrate 1. When the object part position 5 is subjected to trimming, a discharging electrode 4 is arranged above the object part position 5 by interposing a suitable discharging gap (g), and a terminal electrode 3 is brought into contact with a suitable position of the pattern 2. In this state, a high voltage is applied between the terminal electrode 3 and the discharging electrode 4, thereby concentrating electric field in the gap (g) formed in the object part position 5 of the pattern 2. By the effect of spark discharge generated in the gap (g), material of the trimming object part position 5 is evaporated without fusing, so that a desired pattern is formed without damaging the substrate 1.

Title: Permanent magnet motor
Inventor: TAMURA SHINJI
IPC: H02K1/27
Filed: 1996-05-16
Abstract: PROBLEM TO BE SOLVED: To reduce the leakage magnetic fluxes from between magnetic poles in contact, with required strength kept in the iron core of a rotor, and enable the suppression of noise caused by the rigidity of the rotor, by press-fitting a permanent magnet so that it may contact with an elastic mechanism. SOLUTION: A magnetic pole coupling 7 existing between the flank of a permanent magnet 10 and the periphery of the iron core 4 of a rotor is made of a narrow part 7a narrow in diametrical direction and a wide part 7b wide in diametrical direction. In a permanent magnet constituted this way, since the magnetic pole coupling 7 is provided with the said narrow part 7a, the magnetic resistance between the adjacent magnetic poles 6 increases. Accordingly, the leakage of magnetic fluxes decreases between the magnetic poles 6, and it becomes possible to prevent the drop of motor efficiency. Moreover, since an elastic mechanism 13 is provided at a magnet insertion port 5, the permanent magnet 10 and the iron core 4 of the rotor are united, and the rigidity of the rotor is elevated. Therefore, the occurrence of the noise caused by oscillation mode can be suppressed.

Abstract: PURPOSE:To enlarge a dynamic range and to attain the simplification of the circuit constitution, speed-up and hih integration by making the threshold value of a reading means for sweeping with the aid of information stored in a memory loop free from the direction to which a current flows in the reading means, then making the current positive/negative bipolar. CONSTITUTION:Four memory cells of a memory device are constituted of memory loops 101-104, information writing means 111-114 and information reading means 121-124. In order to write information, a current is selectively added to Y lines Y1 and Y2 and X lines X1 and X2, and the writing means where both currents flow is switched, or kept in the previous state. Finally the desired information is written in the memory loop. The information to be written is fed to a Y' line in a selected address. At the time of reading information, a current flows in sense lines S1 and S2. Simultaneously a current flows in the selected Y' line, and the reading means is switched, thereby reading the state of the reading means from the S line. Since a positive/negative bipolar current can flow in the S line, the dynamic range can be enlarged, and high speed action can be possible.

Abstract: PURPOSE:To execute current detection with high accuracy without using a resistor for shunting even in a semiconductor composite circuit due to a bipolar transistor by causing an emitter part to be multi-structure and fetching a detecting current. CONSTITUTION:Darlington connection is executed for two bipolar transistors 1 and 2 and the transistor 1 is made in the multi-emitter structure to have two emitters E1 and E2, and the area ratio of the emitters E1 and E2 is set nearly '1'.

Filed: 1999-04-28
Abstract: PROBLEM TO BE SOLVED: To surely detect a nipping and quickly avoid the nipping by reversing a window glass on open side only when the reducing quantity of rotating speed of a motor is within a preset range.
