IPC: H03H9/64
Filed: 1979-12-13
Abstract: PURPOSE: To reduce the variations in the characteristic, which are caused at the time of mass production, by forming stepwise a shape of the opposed electrode of the elastic surface wave transducer for which a piezoelectric thin film is used.  
     CONSTITUTION: A shape of the opposed electrode 25 is formed stepwise. That is to say, the external shape of the opposed electrode 25 is formed so that the parallel segment in the lengthwise direction of the electrode finger 23, and the orthogonal segment in the lengthwise direction of the electrode finger 23 are repeated alternately. In this case, the parallel segment is arranged at the position opposed to the space part between the electrode fingers 23, and also the orthogonal segment is arranged so that it covers the part of the electrode finger 23. According to this constitution, the variations in the characteristic as a transducer can be reduced remarkably against the relative shift of the mask alignment at the time of production of the elastic surface wave transducer.

Filed: 1991-07-03
Abstract: PURPOSE:To delete an image correctly by applying a deletion energy for deleting a visible image after performing a preliminary deletion thereof using a lower energy than the energy used for deleting the visible image in a recording device which forms and deletes the visible image by changing a white turbid and transparent state thermally. CONSTITUTION:Thermal energy is applied to a recording medium carried from an arrow (a) from a heater 11 to change an image from a white turbid state to a transition state which allows a shift to a transparent state. Next, the existing image is completely deleted by applying the thermal energy to change the recording medium to a transparent state using a heater 15. After that, highlighted pixels to be reoorded are checked and their accumulated heat amounts calculated from a reference area around the highlighted pixels, if the dots are marks which form an image, while no operating action is taken, if the dots are space dots which do not form an image. Finally data is recorded by giving an energy using a thermal head 19.

Abstract: PURPOSE:To make the suppressing of effect possible by a jamming electromagnetic wave to its minimum thereof by switching a feed forward type automatic gain control circuit and a feed back type automatic gain control circuit properly by an output of a pulse width detection circuit. CONSTITUTION:A pulse width of a mono pulse sum signal is detected with a pulse width detection circuit 15 connected to an output terminal T2 to which the mono pulse sum signal is outputted of a mono pulse comparator 2 linked to an antenna 1 which receives electromagnetic waves. It is judged from the pulse width whether or not the signal received is a jamming electromagnetic wave. As a result, when the signal received is the jamming electromagnetic wave, a feed forward automatic gain control circuit 13 connected to the output terminal T2 is switched, otherwise, a feed back automatic gain control circuit 9 is done with a switch 14 which is opened or closed by an output of the detection circuit 15. This makes the suppressing of damage of a tracking apparatus possible and the drop in accuracy of an angle error signal even when the jamming electromagnetic wave with a large power is received.

Title: Refrigerating cycle device
Inventor: MORITA KEIICHI
IPC: F04C28/16
Filed: 1981-10-13
Abstract: PURPOSE:To make capacity variance possible with only one switching valve operated as  well as to aim at simplification in a refrigerating cycle, by interconnecting a cylinder  chamber with a high-pressure side refrigerating pipe of a compressor, while setting up a  pocket part, which comes to clearance for refrigerant, in this bypass circuit. CONSTITUTION:When capacity up is the case, a switching valve 27 is turned to open.  Refrigerant compressed by and discharged from a compressor 20 is inducted into a condenser 21, a capillary tube 22 and an evaporator 23 and serves for a refrigerating action. A part of refrigerant out of the compressor 20 is introduced into a bypass circuit  28 and applies highly intensified back pressure to a check valve 35 via the switching  valve 27 and a pocket part 39 of said bypass circuit. Therefore, a valve body 36 is displaced in defiance of resilient force of a spring 37, closing a bypass port 34. An ample amount of refrigerant is conducted into the evaporator 23 so that capacity upping is attainable. When capacity down is the case, the switching valve 27 is turned to close. Refrigerant discharged from the compressor 20 is checked by the valve 27 and thereby it  does not pass through the bypass circuit 28 any longer. As a result, the quantity of refrigerant discharged from the compressor 20 decreases and capacity down is thus secured.
