Title: Thermal printer
Inventor: MORIMOTO TSUNEHIKO
IPC: B41J25/312
Filed: 1984-04-03
Abstract: PURPOSE:To maintain the force for pressing a thermal head against a recording paper to be constant, by a simple construction wherein a thermal head is pressed through a spring member. CONSTITUTION:A plunger 17a for a solenoid 17 penetrates through a front wall of a carriage 4, and makes contact with a part near a free end of the spring member 15 fixed to the back side of a tiltable member 14. Therefore, when the plunger 17a is protruded by operating the solenoid 17, the member 14 normally attracted in a direction for separating away from the platen 1 by an elastic member (not shown) is energized through the spring member 15, whereby it is tilted with a pivotal point as a center, thereby pressing the thermal head 13 againt the platen 1. By this pressing of the head 13, an ink ribbon (a) pressed against the recording paper fitted on the platen 1, and a heating element in the head 13 is operated to heat, thereby printing.

Filed: 1995-03-27
Abstract: PURPOSE: To prevent knocking by setting an advance value according to temperature of an engine at a time of changing when an automatic gear is changed from a non traveling position to a traveling position and advancing ignition timing with the advance value. CONSTITUTION: An electronic control device 4 takes in a shift detection signal b from a A/T switch 9, a water temperature signal STHW and speed signal c from temperature, speed sensors 8 and 10. Difference between the taken speed signal c and previous taken in signal is operated and if the speed increases to upper limit speed, a speed flag is set ON and if the speed decreases to lower limit speed, the speed flag is set OFF. Whether the A/T switch 9 is OFF or not is determined by the taken in shift signal b and if OFF, that is at traveling position, whether cooling water temperature at this time is less than a determined value or not is determined from the water temperature signal STHW.  If the temperature is less than the determined value, whether the speed flag is ON or not is determined and if it is ON, a value corresponding to the cooling water temperature at this time is read out from a water temperature-advance table and the advance value is set to the value.

Then, pressure impressed on the surface by pressure fluctuation caused in an area to be measured is transmitted to the inner peripheral part of a piezo-electric element 15 by a pressure transmission member 14, and sharing stress occurs inside the element 15 because the outer periphery part of the element 15 is fixed by an upper fixing screw 16, then charge in accordance with the sharing stress is generated in the electrode part on the inner or the outer periphery of the element 15. Thus, the fluctuation of the preliminary stress of the element 15 caused by the distortion in the axial direction of the housing is not caused and the output variation is removed.

Abstract: PURPOSE:To make highly sensitive reagent for estimation of hedrogen peroxide by using a specific imidazole derivative. CONSTITUTION:An imidazole derivative expressed by the formula is used for a reagent for the analysis of hydrogen peroxide. Using such a reagent, hydrogen peroxide and the imidazole derivative expressed by the formula are made to react with each other, so as to produce dyestuff of 1mol with hydrogen peroxide of 1mol. The analysis is performed by detecting the dyestuff thus produced. This reagent is made applicable in a wider sphere as a reagent for estimation by combining the imidazole derivative expressed by the formula with peroxidase and further with oxidase. In other words, in the case when a material to be quantified finally produces hydrogen peroxide under the effect of oxidase, the combination of the oxidase with a reagent system of the present invention enables the estimation of various subject materials through the estimation of the hydrogen peroxide thus produced. In the formula, R<1> denotes an aryl in which an ortho-position or a para-position is substituted by a hydroxyl-radical. R<2> and R<3> denote an aryl, a substituted aryl or a furyl-radical, respectively, and at least one of R<2> and R<3> denotes a furyl radical.
