Title: Thermal printer
Inventor: MATSUKAWA HIROYUKI
IPC: B41J2/325
Filed: 1998-09-07
Abstract: PROBLEM TO BE SOLVED: To sufficiently reduce a friction coefficient between a thermal head and thermal recording paper by preventing occurrence of printing variation. SOLUTION: A color thermal recording paper 3 is nipped between a platen roller 12 and each heating element 17 and is transported toward a discharge passage by a rotation of the platen roller 12 in a forward direction. While each heating element 17 is driven, a friction coefficient between the color thermal recording paper 3 and a thermal head 13 is reduced by virtue of the heat of each heating element 17 so that a piezoelectric element 19 is not driven. A vibration controller 21 calculates a driving time of the piezoelectric element 19 based on an average driving time of the previous heating elements, then the piezoelectric element 19 is driven after the average driving time has elapsed. A resonance vibrator 20 is resonated, then the thermal head 13 is vibrated so that the friction coefficient is reduced.  The similar operation is repeated and a yellow image is thermally recorded till the last line is completed. The thermally recorded yellow thermal coloring layer is optically fixed by an ultraviolet lamp 22 for yellow. After that, the platen roller 12 is rotated in the reverse direction so that the color thermal recording paper is returned to a starting position for the thermal recording. Thus, each image recording for magenta and cyan is performed, similarly.

Title: Measuring method of acoustic output
Inventor: HASHIMOTO YOSHIKI
IPC: G01H3/12
Filed: 1984-11-29
Abstract: PURPOSE:To measure acoustic output power easily at a practical particle speed level in a short time by inserting a transmitter in which an annular electromagnetic oscillation detector is fitted into an ultrasonic oscillation system, and detecting data at a node position of the standing wave in the transmitter. CONSTITUTION:The transmitter 10 in which the annular electromagnetic oscillation detector 12 is fitted is interposed between an acoustic load 11 and an oscillator 8, and the detector 12 is fixed at a node position of the standing wave in the transmitter to measure acoustic output power through the operation of an acoustic output meter part 9 or 9'. Namely, the transmitter 10 is run through the hole 4 of the detector 12 of this structure or circuit to transmit oscillation, and then voltages proportional to the particle speed are induced across coils 3 and 3'. Therefore, the sum of the two voltages is also proportional to the particle speed, so when the position where the sum voltage is reduced to minimum is derived, the position is as the node of the standing wave. The differential electric power between the coils 3 and 3' at the node position is proportional to force F, so the acoustic output power is found by calculating the product of the difference voltage and sum voltage.

Title: Wide dynamic range current source circuit
Inventor: HAYASHI SHIGERO
IPC: G05F3/22
Filed: 1989-09-28
Abstract: PURPOSE:To enlarge a dynamic range by permitting a current larger than that of a non-linear operation area in a first current mirror circuit to flow by means of a second current mirror circuit. CONSTITUTION:The second current mirror circuit 2 consists of a pair of npn- type bipolar transistors Q3 and Q4 and a resistor R2. The collector of the transis tor Q3 is connected between the collector of a first transistor Q2 in the first current mirror circuit 1 and a resistor R1, and an emitter is connected to the ground GND. When a voltage impressed on the control voltage input terminal of the second mirror circuit 2 is fixed, a constant current is pulled out from the second current mirror circuit 2 as against the transistor of an input-side current path in the first current mirror circuit 1. Consequently, the inter-terminal voltage of a resistance element connected to the collector does not come to depend on the change of a control voltage. Thus, the circuit can be used as a current source circuit with a wide dynamic range.

Title: Dry control system for grain dryer
Inventor: KOREHISA MASAKI
IPC: F26B17/14
Filed: 1989-09-27
Abstract: PURPOSE:To reduce cost by comparing the differential temperature between the temperature of draft on a feed side and a discharge side which passes through a drying chamber with the temperature of grains in the drying chamber and halting the drying operation when the temperature of grain exceeds a specified temperature and eliminating the need for a circulation sensor. CONSTITUTION:During drying operation, a hot air temperature sensor 13 detects the temperature of hot air in a hot air chamber 12 while an exhausted air temperature sensor 15 detects the temperature of exhausted air in an exhausted air chamber 14. The differential temperature between the detected hot air temperature and the detected exhausted air temperature is calculated. The temperature of grains in a drying chamber 1 is detected by a grain temperature sensor 11 and the detected grain temperature is compared with the aforesaid differential temperature. When the detected grain temperature exceeds a specified temperature, it is detected that the grains fail to circulate so that the hot air generated from a burner may be suspended. As a result, the drying operation is switched over to draft drying induced by open air to be sucked and exhausted by an exhauster 7 and the grains are dried.
