Title: Auto reverse type cassette tape recorder
Inventor: SHIMADA HIROMICHI
IPC: G11B15/08
Filed: 1985-08-22
Abstract: PURPOSE:To remove erasing residual of a preceding signal at a terminal part and an unnecessary muting recording part by switching a tape traveling direction after a fixed time and turning a cassette tape recorder to temporarily stopped status when a reader tape part is detected during auto-recovery muting operation. CONSTITUTION:When a reader tape detecting means 22 detects a reader tape during the auto-recovery muting operation of a mechanism, tape traveling is continued only by the fixed time clocked by a timer means 34. Then, the tape traveling direction is automatically switched by a reverse operation command means 24 and a command for releating the the auto-recovery muting operation is applied to an auto-recovery muting operation command output means 26 by the output of an auto-recovery muting operation command means 28. When the command from the means 26 is interrupted, a mechanism driving control means 21 controls so that the mechanism is turned to the temporarily stopping status of recording. When the reader tape part is detected during the auto- recovery muting operation, the erasing residual of the preceding recording signal can be removed and a muting recording part immediately after the switching of tape traveling can be removed.

Title: Sense amplifier circuit
Inventor: IKENO TOMOKAZU
IPC: G11C17/18
Filed: 1992-07-13
Abstract: PURPOSE:To prevent an increase in the response time required for reading data by connecting in parallel a current source circuit to a data cell circuit being a reading object. CONSTITUTION:The current source circuit 5 is connected in parallel to the data cell circuit 4 being the reading object of a sense amplifier circuit. Thus, since a transistor N1 in a source follower circuit 1 supplying constant voltage to the data cell circuit 4 is not cut off throgh-out an entire operation period, a desensitized period in the source follower circuit 1 at the time of the rise of read current is dissolved. Thus, by suppressing dulling in the rise of read current, an increase in the response time required for reading the data is prevented.

Title: Ink jet printer
Inventor: KOIDE YOSHIO
IPC: B41J2/115
Filed: 1988-07-27
Abstract: PURPOSE:To control printing accurately by a method wherein a charged quantity of an ink particle is detected based on an electric signal statically induced with a deflecting electrode by a pass of the ink particle under a state in which voltage for generation of a deflecting electric field is not applied to the deflecting electrode. CONSTITUTION:When a period for detection of a charged quantity comes, a phase control circuit 38 detects a charged quantity of an ink particle at each angle changing a phase of a charged pulse 22 to a particle making signal 16 by each specific angle. A charged ink particle in this case should not stick to paper to be printed by receiving deflection. Therefore, application of voltage for generation of deflecting electric field to a deflecting electrode 20a is interrupted, and all ink particles are made to go straight ahead. Positive and negative pulses are generated respectively at the start and at the end of passing of a charged ink particle group by a charged pulse at each phase. Thereby, a phase when a highest amplitude pulse in charged quantity detection waveforms appear is an optimum phase of the charged pulse. By establishing the phase of the charged pulse 22 to an optimum phase, ink is charged instantaneously when the ink is made into particles, and printing is accurately controlled.

Title: Method and device for detection of knocking for internal combustion engine
Inventor: HATSUTORI TADASHI
IPC: G01L19/06
Filed: 1980-12-26
Abstract: PURPOSE:To detect the knocking of an internal combustion engine with simple and compact constitution with high accuracy, by eliminating the static hydraulic pressure from the composite pressure of the hydraulic pressure of the lubricating oil of the internal combustion engine and the pulsating hydraulic pressure which is according to the knocking. CONSTITUTION:When knocking arises, the cylinder wall surface has a distortion to produce the pulsating pressure to the lubricating oil. Then the composite pressure of the pulsating pressure and the static hydraulic pressure is transmitted to the lower surface of a diaphragm 203a of a distortion meter 203 via a diaphragm 202 and a noncompressive liquid 215. On the other hand, the synthetic pressure is applied to a compressive material 209 via a pressure lead-in hole 208. Thus the pulsating pressure is absorbed, and only the static pressure is applied to the upper surface of the diaphragm 203a via the liquid 215. Then the static pressure is eliminated by a differential pressure process, and thus only the pulsating pressure is detected by the meter 203. In such way, the knocking detection is possible with a simple and compact constitution and high accuracy.
