Title: Comparator
Inventor: TAKEDA MASAO
IPC: H04B3/10
Filed: 1982-07-07
Abstract: PURPOSE:To realize a low cost and miniaturization of a comparator, by providing the 1st comparator which compares two kinds of threshold voltages, the 2nd comparator and a logical circuit, then setting automatically the threshold voltages of different hysteresis widths set after restoration in response to those two types of threshold voltages. CONSTITUTION:Resistances R8 and R9 are set so that the threshold value Vth3 is set between the value Vth1 and the value Vth2' obtained after recovery. When resistances R6 and R7 or R7 are short-circuited and opened, these resistances are set so that the threshold value is set to Vth2 or Vth1, and Vth2' or Vth1' for the minus input terminal of a comparator 8. The voltage of said minus input terminal is set to Vth1 when a pilot signal is lowered in level than the reference level by 1db. The output of the comparator is set to ''1'' when the signal level is normal. As the voltage Vth1 of the minus input terminal of a comparator 9 is higher than the value Vth3, the output of the comparator 9 is set to ''O''. Then a TRQ2 short-circuits the resistance R7. This enables control. When the level of the pilot signal is made higher than the reference level by <=1db, the R7 is recovered from short-circuiting. Then the voltage of the minus input terminal of the comparator 8 is set to Vth1' obtained at a time point of restoration. The same effect is obtained in a case where the pilot signal is lowered by 5db. An IC formation enable part is shown by 7'.

Title: Surface acoustic wave device
Inventor: OKAMOTO TAKESHI
IPC: H03H9/02
Filed: 1982-07-06
Abstract: PURPOSE:To attain a unidirectional transducer with an improved yield, by constituting an upper electrode provided on a piezoelectric thin film on an elastic substance substrate with plural electrodes arranged separately in a direction. CONSTITUTION:A lower electrode comprising a rectangular electrode 14 is provided on the elastic substance substrate 12 of a piezoelectric substrate 1 having a piezoelectric thin film 13 on the elastic substrate 12 and an upper electrode comprising comb electrodes 15A-15C is provided on the piezoelectric thin film 13 to constitute a so-called single phased transducer. Since the electrode width W and the interval L are widened by twice or four times in comparison with a connertional normal electrode because those of the comb electrodes 15A-15C are lambda0/2, the accuracy of the processing technology is relaxed and the yield is improved. Thus, the cost reduction is attained and the manufacture of high frequency transducers is made easy.

IPC: H02N2/00
Filed: 1998-04-28
Abstract: PROBLEM TO BE SOLVED: To obtain a surveying instrument in which a motor formed in a unit can be used to turn a vertical axis, by a method wherein an arm is installed at a motor case so as to protrude to the outside, and the arm is fixed around an instrument-body casing via a universal joint error absorption mechanism. SOLUTION: A hollow ultrasonic motor 40B which turns a telescope is installed at the other end of a horizontal axis 32. That is to say, the output shaft 41 of the ultrasonic motor 40B is connected directly to the horizontal axis 32, and one arm 46 which is installed so as to protrude at a motor case 40a is fixed to a pillar-shaped-part formation wall via a universal joint error absorption mechanism B so as not to be turned. Consequently, an unexpected load (stress) which is generated by attaching and fixing the ultrasonic motor 40B to a part between the horizontal axis 32 and the pillar-shaped-part formation wall is not generated at all between the output shaft 41 which is fixed to the horizontal axis 32 and a rotor 44 as well as between the motor case 40a which is attached so as to be rotatable with reference to them and a stator 42.

Abstract: PROBLEM TO BE SOLVED: To increase the strength at welds and ensure an enough pressure resistant reliability by a method wherein split bodies of a resin product, which are produced by integrally welding the resin split bodies, are made of a polyamide 6 and, at the same time, the respective split bodies are integrally joined by injection-welding with a polyamide 66. SOLUTION: When split bodies 2 and 3, the shapes of which are obtained by bisecting an intake manifold 1 along an axial crosssection, are respectively injection-molded out of a resin material made of a polyamide, notched parts 2b and 3b are formed over the whole periphery of the outer peripheral part on respective joint areas 2a and 3a sides. After being cooled and hardened, the split bodies are placed in a mold under the state that the joint areas 2a and 3a are abutted against each other, the notched parts are injection-welded. As a welding resin 4, the resin material made of a polyamide 66 is used so as to ill in a filling hole 5 formed by both the notched parts 2b and 3b. After the cooling and hardening of the resin material, the mold is opened and predetermined after workings such as deburring and the like are executed so as to complete an intake manifold 1.  Thus, the strength at the weld can be improved and the high pressure resistant reliability can be ensured.

Title: Protective coating material for annealing for grain-oriented electrical steel sheet
Inventor: KONNO TOYOHIKO
IPC: C23C22/00
Filed: 1987-05-16
Abstract: PURPOSE:To stabilize secondary recrystallization by incorporating a specified amt. of ferromolybdenum nitride into a magnesia-based protective coating material for annealing. CONSTITUTION:This protective coating material for annealing is obtd. by adding 0.2-20pts.wt. ferromolybdenum nitride to 100pts.wt. magnesia. The nitride has 600-900 deg.C decomposition temp. and is effective in raising the partial pressure of nitrogen in an annealing atmosphere from the early stage of finish annealing. The nitride makes the partial pressure of nitrogen uniform in the lateral direction of a coil over a wide temp. range like ferromanganese nitride and Mo oxide produced after the release of nitrogen hardly causes film defects. Accordingly, when the protective coating material is used, secondary recrystallization especially during finish annealing is stabilized and a product having superior magnetic characteristics can stably be produced.

Abstract: PURPOSE:To prevent increase of accumulative errors of control timing, by dividing the output pulse of a pick up means for detecting the ring gear of a fly-wheel with a specified dividing ratio having a constant period and a constant interval in relation to the explosion period of an engine. CONSTITUTION:The ring gear of a fly-wheel in an engine is detected in a pick-up unit A, so that the control timing of the engine is set on the basis of the counted value of a detected output pulse. In this occasion, the output pluse from the pick-up unit A is inputted to a programable dividing circuit C through a wave forming unit B, so that the output pluse is devided with a prescribed deviding ratio. And a value corresponding to each round-up value and the round-down value, which is equivalently to an explosion period, of the output pluse numbers in the pick up unit A is set alternately by an engine control unit D as the abovementioned dividing ratio. Thereby, it is possible to prevent increase of accumulative errors of control timing caused by the tooth number of ring gear set as a prime number.

Abstract: PURPOSE: To minimize the thickness of an adiabatic material and also to facilitate sticking work of the adiabatic material by a method wherein a hydrate performing endothermic or exothermic reaction according to change in temperature is incorporated in a regenerative tank connected in circulation to a heating unit, heat radiation in the regenerative tank is controlled to accelerate a regenerating action chemically.  
     CONSTITUTION: Hot water tanks 9, 15, 32 for hot water coming from a solar heat collecting unit are made to work as a regenerative tank, and a hydrate performing endothermic or exothermic reaction according to change in temperature like hydrate of calcium chloride is incorporated in the hot water tanks. Upon receipt of the solar heat, the hydrate is decomposed to separate water content through endothermic reaction in accordance as water temperature rises. Then, where the solar heat decreases and water temperature drops accordingly, the hydrate is combined to generate heat, thus controlling temperature drop. Since heat radiation can be controlled through endothermic and exothermic reactions according to change in temperature, thickness of an adiabatic material can be minimized and a sticking work can also be decreased.
