Title: Magnetic recording amplifier
Inventor: TANAHASHI MAKOTO
IPC: H03F1/34
Filed: 1986-02-20
Abstract: PURPOSE:To smooth the frequency characteristic near the resonance point of a magnetic head without using a damping resistance by operating a magnetic recording amplifier so that it has a constant current characteristic in a low frequency area of a recording signal and has a constant voltage characteristic in a high frequency area. CONSTITUTION:A voltage feedback circuit F surrounded with a long and short dash alternating line feeds back the voltage in the output side (point A) to the input side (point B) by a resistance R1 and a capacitor C1. The recording signal inputted from a terminal T1 at the recording time is supplied to a magnetic head 4 with the constant current characteristic by a recording amplifier 10. A voltage eR of an output terminal rises in the low frequency area of the recording signal in accordance with a formula eR=iR.omegaL where iR is the recording current and Z(omega) is the impedance of the magnetic head 4, and this voltage is fed back as a feedback voltage to the input side. Consequently, omegaL is very small and the feedback quantity is very small in the low frequency area, but the impedance Z(omega) rises quickly by resonance of the magnetic head 4 near the resonance point of the magnetic head 4 and the voltage eR rises quickly and the feedback quantity is increased there.

Title: Slip control device for vehicle
Inventor: YAMASHITA TETSUHIRO
IPC: F02P5/15
Filed: 1993-01-27
Abstract: PURPOSE:To prevent the occurrence of an engine stall during a start on an ascending slope, improve acceleration properties and improve the driving stability. CONSTITUTION:When, during running on an ascending slope, the number of revolutions of an engine N is lowered owing to slip control, it is decided that a high mu-state is produced and a mu-decision flag F is set to '1'. During a time in which the flag F is 1, slip control is suspended. After the number of revolutions is increased by alpha(alpha=200rpm) from a point of time B1 when the number of revolutions is lowest, return to slip control is effected. Even during a time in which the flag F is '1', computation of a final control level FC (k) of slip control is continued. During return to slip control, a first correction value (a) is added to a computation value of the FC (k) for a specific time ta to reinforce suppression of the occurrence of a slip. When a rate of increase of the number N of revolutions of an engine is high, it is decided that a low mu-state is produced and the mu-decision flag F is set to '2' to execute slip control. However, when it is decided that a low mu-state is produced, a second correction value (b) is added for a given time tb to reinforce suppression of the occurrence of a slip. When, during a start on an ascending slope, backward movement occurs, a period of a flange F='1' is extended to a time therebefore or thereafter to reinforce an objective function.

Title: Piezoelectric vibrator and fine adjustment method of its frequency
Inventor: NAKAI TOSHIYUKI
IPC: H03H3/04
Filed: 1988-02-17
Abstract: PURPOSE:To continuously and efficiently apply fine adjustment to the frequency in air by evaporating a metallic coat film by a laser beam through a transparent cover and depositing the evaporated material onto a main electrode of the vibrating chip. CONSTITUTION:The vibrating chip 6 whose front and rear face are provided with a main electrode 7 is supported by a support 4 of a lead terminal 3 by a conductive adhesives 5. The metallic coat film 9 is applied to the middle part of the transparent glass cover 1 by the vapor-deposition method. The vibrating chip 6 is subjected to airtight sealing by the case 2 and the cover 1 by using an adhesive 8. A YAG laser beam is radiated externally through the cover 1 while being focused near the coating film 9. The YAG laser beam evaporates only the coat film 9 selectively momentarily. Since the evaporated metal is deposited on one face of a main electrode 7 arranged to the vibration chip, the oscillated frequency of the vibration chip 6 is decreased by the mass addition effect. The YAG laser beam is applied repetitively to obtain a desired oscillation frequency. Thus, the frequency can be adjusted minutely continuously and efficiently in air.

Filed: 1991-02-28
Abstract: PURPOSE:To expose and transcribe a fine isolated pattern by a method wherein one periodic pattern and another pattern which have been formed in different places on one original plate are overlapped and exposed to light and a projection-type aligner provided with a specific illumination optical system is used. CONSTITUTION:One pattern PA which is to be overlapped and exposed to light is formed in such a way that, as one example, three light-shielding patterns PA1, PA2, PA3 are formed in a line-and-space shape (at a duty of 1:1). A first exposure operation is executed to a resist layer on a wafer W. An isolated line pattern which is to be formed on the wafer W is originally the light- shielding pattern PA2. The other pattern PB which is to be overlapped and exposed to light is arranged instead of the pattern PA, and a second exposure operation is executed to the same position on the wafer W. At this time, the width Db of the pattern PB is decided to be narrower than the interval Da between the line patterns PA1, PA3 on both sides of the pattern PA and to be larger than the line width of the line pattern PA2.
