Patent JP-H0192816-A (JP)
Title: Driving circuit
Inventor: OSHIZAWA HIDEKAZU
IPC: H01F7/18
Filed: 1987-10-02
Abstract: PURPOSE:To attain stably power supply control to a load by forming a feedback control loop for an operational amplifier through a negative feedback circuit when a driving transistor (TR) is OFF. CONSTITUTION:Since the feedback control loop based upon the operation amplifier 13 is formed through the negative feedback circuit 30 and voltage Vp' is fed back even when the TR is OFF, the operational amplifier 13 is not saturated and its output voltage is not boosted. Since the TR 4 is not saturated when the TR 4 is turned from OFF to ON in the succeeding time, overshooting with a large current supply Ia is not generated and the overshooting can be suppressed to a negligible level. Consequently, stable power supply control to a solenoid 1 can be attained.

Title: Automatic sorting apparatus for fruits or the like
Inventor: SUZUKI KAZUHIRO
IPC: G01G15/00
Filed: 1983-12-26
Abstract: PURPOSE:To immediately detect the drift of a zero point of a load cell beyond a tolerance limit and thereby to facilitate the zero point adjustment, by detecting whether a detection output of a weight detector is within a prescribed range or not, and by controlling a display means for lighting on the basis of the above detection. CONSTITUTION:Based on an output of an AD converter 8, CPU1 detects sequentially the weight of each cup passing on a load cell 4. When a cup loaded with a substance to be sorted is detected, the weight of an empty cup is read out of RAM13, the weight of the substance to be sorted is calculated therefrom, and sorters 11-1-11-n are controlled according to the result of the calculation. CPU1 samples the output of the AD converter 8 to determine whether the value thereof is within a prescribed range in ROM2 or not. A light-emitting diode 10 is lighted when said value is within the range, and is extinguished when it is beyond the range. The light-emitting diode 10 is extinguished, on the other hand, when the drift of the zero point of the load cell 4 is beyond a tolerance limit. Thus, the zero point adjustment is performed easily.

Title: Banknote storing method
Inventor: IMI YUJI
IPC: B65H29/18
Filed: 1985-11-07
Abstract: PURPOSE:To make the storage of new banknotes smooth by elevating the bottom plate of a storage box when banknotes are stored, to decrease the contact pressure between a conveying belt and the banknotes on the bottom plate, and then by slightly lowering the bottom plate. CONSTITUTION:A banknote introduced in the direction R is advanced along the guide surface of a direction changing rail 11, and drive force is obtained from a retaining roller 12 to convey the banknote toward a belt pulley 2 where both edges of the banknote 10 are guided along the upper surface of a rotary guide plate 22. The banknote 10 is then slightly pressed against a conveyer belt 5 so that it is conveyed to a position regulating lever 26 by friction force between the banknote and the belt 5. Under a storing instruction the rotary guide plate 22 is rotated upward, and therefore, the banknotes 10 is stacked onto the topmost one of banknotes 10A having been already stored on a bottom plate 25 which has been elevated in association with the rotation of a motor. Then the motor is slightly reversed to lower the bottom plate 25 to allow the rotary guide plate 22 to return its original position. Thereby it is possible to make the storage of new banknotes smooth.

Title: Musical sound generator
Inventor: FUJII KATSUYOSHI
IPC: G10H7/00
Filed: 1990-09-18
Abstract: PURPOSE:To reduce a memory capacity by decreasing the band waveform data bit length of a band waveform generating part with the increase of the frequency, and controlling the amplitude of each band waveform data. CONSTITUTION:A band waveform generating part 1 divides musical sound signals into plural frequency bands, generates the band waveform data, and stores the waveform of each frequency band in a bit length memory 2 as the digital data of the bit length corresponding to the amplitude. At that time, the bit length is decreased with the increase of the frequency of each frequency band. Then, the waveforms are read out at every frequency band according to musical intervals designated at the time of synthesizing the musical sounds, and amplitude coefficients generated by a band waveform amplitude coefficient generating part 3 are multiplied by a multiplier 4 in order to control the amplitudes of each band waveform data. Then, each band waveform data is amplified and synthesized. Thus, the musical sounds whose timbres are different can be synthesized by the reduced memory capacity.

IPC: B41J2/36
Filed: 1987-10-01
Abstract: PURPOSE:To realize a printed density with favorable linearity through using a counter or memory with a small capacity, by time-sharing the energization of a thermal head, and setting the total energization time and the number of times of the time-sharing energizations to predetermined values. CONSTITUTION:A memory 3 for outputting predetermined stored data synchronously with a clock signal inputted is provided, and a comparing circuit 4 for comparing the stored data outputted from the memory with input data designating a gradation and for controlling an energization tie for a thermal head 5 is provided. The memory 3 outputs the stored data synchronous with the clock signal inputted, whereas the comparing circuit 4 compares the stored data with the input data designating the gradation, and outputs a control signal according to the result of comparison. The energization time for the thermal head 5 is controlled according to the control signal. The head 5 is energized on a time-sharing basis to determine one gradation, and the stored data is so set that the total energization time and the number of times of the time-sharing energizations will be predetermined values, respectively. Therefore, a large number of gradations can be specified by a small number of pieces of stored data, and a printed density with favorable linearity can be realized without need for a considerable increase in the rate of variation of the recorded data.

Abstract: PURPOSE:To prevent the decline in the impurity concentration on a semiconductor substrate surface in later heat treatment while avoiding the increase in the contact resistance between a silicide and a semiconductor substrate by a method wherein, after forming the silicide, impurity ions are implanted tn the interface between the silicide and the semiconductor substrate. CONSTITUTION:Within a semiconductor device in the structure coming into contact with a silicide film 5 in impurity diffused layers 2 and connecting holes inside a semiconductor substrate 1, after forming the silicide film 5, an element in the same type as that of the impurity diffused layers 2 is ion-implanted (a) in the parts near the interface between the silicide film 5 and the impurity diffused layers 2 through the silicide film 5. Through these procedures, since the impurity in the same type as that of the impurity element in the impurity diffused layers 2 is abundantly contained in the silicide film 5, the absorbed diffusion of the impurity element in the impurity diffused layers 2 in the silicide film 5 in the later heat treatment can be avoided, resultantly enabling the increase in the contact resistance between the silicide film 5 and the impurity diffused layers 2 to be avoided.
