Title: Circuit apparatus for processing signal of inductive measuring sensor
Inventor: HERUMUUTO KUNISU
IPC: G01D5/244
Filed: 1988-03-10
Abstract: PURPOSE: To prevent the error or temperature variation of a sensor from having effect on the output signal by providing means for connecting the coil of an inductivity measuring sensor with a comparator through a coupling capacitor and compensating for the charging thereof. CONSTITUTION: A signal induced in the coil 10 of an inductivity measuring sensor is applied through a coupling capacitor 11 with a peak value detector 14. A peak value memory capacitor 18 is charged with the positive half wave of a measuring sensor through a diode 17. Charges taken away tram the coupling capacitor 11 are compensated by a current flowing into a charge compensation resistor 12. Voltage of the peak value memory capacitor 18 is used for varying the threshold voltage of a differential amplifier 16. When the output signal from the coil 10 exceeds a variable threshold voltage, an output signal appears at the output terminal 28 of the differential amplifier 16.

Abstract: PURPOSE:To prevent a lid from getting off from a bowl while solid ingredient such as ice is cut in the bowl even in the case the lid is washed with hot water and lid lips contract, resulting in a decrease in fitting force of the lid on the bowl, by a method wherein a shoulder part having a large diameter is formed around the upper periphery of the bowl, and a protrusion is provided on the lid to be fitted on the bowl. CONSTITUTION:A detachable bowl stand 23 is mounted on a main body and a bowl 24 is fitted in the bowl stand 23. A detachable lid 25 has two or more elastic lips 27 and is fitted on the upper opening of the bowl 24.

Abstract: PURPOSE:To prevent the quality of printed images from being deteriorated due to abrasion and ensure high reliability, by providing a recording needle for a recording head by a thick film printing method. CONSTITUTION:A ceramic comprising manganese oxide and silicon dioxide as main constituents is used as a material for an electrode substrate, and tungsten is used as a material for a recording needle.

Tungsten as the material for the recording needle is mixed with an organic binder, and the resultant mixtures is ground and is kneaded to produce a conductor paste. The paste is applied to the green sheet by printing, followed by firing in a reducing atmosphere to produce the recording head. When printing is conducted by the recording head in which the hardness of the recording needle is higher than that of the substrate electrode, the electrode substrate is abraded faster than the recording needle, so that a recording end face of the head is constantly maintained in the condition wherein the recording needle is projected from an end face of the electrode substrate.

Abstract: PURPOSE:To detect the continuous change in position of a body to be checked, by providing a position detecting optical fiber bundle which is formed by arranging a plurality of fibers having the same diameter in a zigzag shape or in a matrix shaped in a rectangular form, by providing an optical fiber bundle for setting a pair of detecting ranges, and converting light from a light source through the optical fiber bundles into electric signals in correspondence with the amounts of the received light rays. CONSTITUTION:When a body to be checked 51 reaches a light receiving region of a light receiving fiber bundle 13, the reflected light from the body to be checked 51 is inputted to a light receiving surface 13a of the light receiving fiber bundle 13 in response to the position of the body to be checked 51. Therefore, an output signal C of a photoelectric converter 16 is increased in correspondence with the amount of the received light. Since an output signal E of an operational amplifier 20 is linearly changed from the maximum voltage to the minimum voltage, the continuous change in position of the body to be checked 51 is detected. When the body to be checked 51 is present in the entire light receiving region of the light receiving fiber bundle 13, only the reflected light of the body to be checked 51 is inputted to the light receiving fiber bundle 13, and the output signal C of the photoelectric converter 16 becomes the maximum level.

IPC: B41J2/505
Filed: 1986-03-14
Abstract: PURPOSE:To precisely connect the image of lines to each other, when the resolving power of a line feed motor is different from that of a printing head, by adjusting the number of dots applied to the printing head to perform the printing of an image. CONSTITUTION:When the resolving power of a line feed motor is different from that of a printing head, the number of dots applied to the printing head are adjusted to perform the printing of an image. For example, when the number of dots of the printing head are 24 are the resolving power thereof is 1/180 inch=about 0.14mm, if only 20 dots from among 24 dots are used to perform printing, the size of the image comes to 20/170 inch=1/9 inch=about 2.28mm. When the resolving power of the line feed motor is 1/216 inch=about 0.12mm, if a line feed pitch is set to 24/216 inch=1/9 inch=about 2.28mm, only 20 dots are used to perform the printing of an image having a size of 1/9 inch and, after the line feed of the same 1/9 inch is performed, only 20 dots are again used to perform printing and line feed operation of 1/9 inch is repeated. Therefore, the images of lines can be precisely connected to each other.

Title: Air conditioner control system
Inventor: AOYAMA NOBUO
IPC: G05B17/02
Filed: 1991-03-20
Abstract: PURPOSE:To correct temperature/humidity setting values in automatic mode and prevent a drastic change in the temperature and humidity when starting the operation of an air conditioner during rotation-based suspension. CONSTITUTION:The measured values of temperature/humidity sensors 81 to 8n, which measure the temperature and humidity in an air conditioning area which controls the temperature and humidity in air conditioners 71 to 7n, are input into a temperature/humidity measurement collection means 3, so that the newest measured values may be stored. When starting the operation of one of the air conditioners 71 to 7n, the maximum value about the change in the temperature/humidity measured values generated at each temperature/humidity sensors 81 to 8n are stored previously. Then, they are stored in a starting time temperature/humidity properties memory means 4 as a temperature/humidity change predicted value and input into a temperature humidity setting value decision making means 5 together with the signals of a temperature humidity measured value collection means 3 and an air conditioner operation control means 2. A corrected temperature humidity setting value of this temperature humidity setting value decision making means 5 is input into a temperature humidity control means 6 where each of the air conditioners 71 to 7n is controlled until it reaches the corrected temperature setting value. It is, therefore, possible to prevent a drastic change in the temperature and humidity when starting the operation of the air conditioners 71 to 7n under suspension.
