Title: Detection of wire-breaking of heating element
Inventor: YAMAMIYA OSAMU
IPC: F02P19/02
Filed: 1982-04-02
Abstract: PURPOSE:To correctly detect the wire-breaking from the length of the time by measuring the time necessary for a group of heating element to reach a prescribed heating state, in an apparatus consisting of a plurality of heating element connected in parallel such as glow plugs for Diesel engine. CONSTITUTION:When electric current supply is started for four glow plugs 9 (9a-9b), the temperature of the glow plug 9 sharply rises, and the voltage ratio reduces together with the rise of the temperature, since the resistance of plug 9 possesses a positive temperature coefficient. When the total resistance value of all the glow plugs 9 becomes a prescribed value (corresponding to about 900 deg.C), the output of a voltage comparison circuit 12 becomes H, a main relay 3 is put OFF by a driving a circuit 23, and a contact 5 is opened. Then it any one of the glow plugs 9 is disconnected, the time necessary for the total resistance value of all the glow plugs to reach a prescribed value is shortened, and an output is generated in a wire-breaking detection circuit 6 according to the result of the comparison between the above-mentioned time and a reference time, and a warning indication lamp 31 comes ON.

Title: Disk device and information signal transmitter-receiver
Inventor: HARAGUCHI HIDEO
IPC: G11B21/08
Filed: 1994-03-25
Abstract: PURPOSE:To enhance the operation rate of a disk device. CONSTITUTION:A 2-head HDD device concerned has two heads 1 and 2, and while the head 1 is operated to read out data during a span of 20 (msec), the head 2 is operated for access. Then, while the head 1 is operated to access a span of 20 (msec), the head 2 is operated to read out the data. In other words, an access time of the head 1 and a reproducing time of the head 2 is superposed on a reproducing time of the head 1 and an access time of the head 2. Consequently, the access time is virtually zero by this 2-head HDD device.

Title: Combine
IPC: A01F12/60
Filed: 1992-03-16
Abstract: PURPOSE:To effectively utilize the reserve tank capacity for holding grains in reaping operation and to improve the running stability without necessitating the operation by the operator. CONSTITUTION:A main tank 5 and a reserve tank 12 for holding grains supplied from a thresher 4 are placed at a side and under the thresher, respectively. The amount of grains stored in the reserve tank 12 is detected by a grain quantity detecting means S1 and the supply of grains from the thresher 4 to the reserve tank 12 is interrupted by interruption means 13-15 controlled by a controlling means 100. The controlling means 100 allows the supply of grains to the reserve tank 12 by inactivating the interruption means 13-15 when the amount of grains in the reserve tank 12 is decreased below a preset level G based on the detection information transmitted from the grain quantity detecting means S1 and stops the supply of the grains to the reserve tank 12 by actuating the interruption means 13-15 when the grain quantity in the reserve tank 12 reaches the preset level G.

IPC: G06G7/186
Filed: 1995-03-15
Abstract: PURPOSE: To optimize set ring time for all the output by providing a correction signal generator in an integrator and inputting a correction signal which shortens the set ring time of an operational amplifier by the correction signal generator to the integrator. CONSTITUTION: A correction pulse e2 generated from a programmable correction pulse generator 5 is supplied to one input terminal of the slow-speed operational amplifier 8 of the integrator (resistor 13, slow-speed operational amplifier 8 and capacitor 14) via a resistor 12. The polarity of the correction pulse e2 is the one opposite to the polarity of differential potential generated when a step voltage e1 rises. The amplitude (pulse height) and pulse width of the correction pulse e2 are selected so that the product (pulse area) of them can be equal to the integral capacity (amplitude is integrated by time) of the differential potential.  The change of potential V is reduced by setting the pulse area equal to the integral capacity of the differential potential, and a transient voltage superimposed on an output voltage e3 is reduced, which optimizes (shortens) the set ring time of the output voltage e3.

Title: Production of phosphor
Inventor: ISHII TAKASHI
IPC: C09K11/08
Filed: 1978-05-11
Abstract: PURPOSE: To obtain a magnesium zinc orthophosphate base phosphor with remarkably enhanced water resistance by adding a predetermined amt. of ZnO and/or ZnS to phosphor raw material mixed powder of zinc orthophosphate, magnesium phosphate and an activator followed by calcination.  
     CONSTITUTION: 0.2W2.0 wt% of ZnO and/or ZnS is added to coprecipitated crystal mixed powder of zinc orthophosphate, magnesium phosphate and manganess phosphate as an activator followed by calcination at 900W1050°C. The resulting magnesium zinc orthophosphate phosphor is not immediately hydrolyzed when suspended in water or a photosensitive resist soln., and hence the phosphor can be preserved over a long time. Accordingly, the productivity is enhanced, the sensitivity of a photosensitive resist is not changed at all during production, and defects such as a pinhole phenomenon and exfoliation of a photosensitive element can be eliminated.

Title: Magnetic recording medium
Inventor: KATSUTA YOSHIHARU
IPC: C09D5/23
Filed: 1985-03-20
Abstract: PURPOSE:To prevent the decrease in the output in a middle frequency range by using iron oxide magnetic powder of which the average of particle void fraction is specific vol% or below for the magnetic powder of at least either of two upper and lower magnetic layers of which the coercive force or the particle size of the magnetic powder has a specific relation. CONSTITUTION:The magnetic layer which is provided on a substrate and contains the magnetic powder and binder is made into the two-layered structure consisting of the upper and lower layers and is so formed as to satisfy the conditions of the equations I, II. The output in the low and high frequency ranges is improved by satisfying the equation I. The decrease of noise is attained by satisfying the equation II. The iron oxide magnetic powder of which the particle void fraction is average <=5vol% is used for the magnetic powder of at least either of such upper and lower layers in the magnetic layer made into the double-layered construction. The decrease in the output of the middle- frequency range (about 1-5kHz) which is heretofore considered the disadvantage with the magnetic layer made into the two-layered structure is thus suppressed and the expansion of the dynamic range in the entire range from the low to high frequency range is made possible.
