Filed: 1982-03-20
Abstract: PURPOSE:To measure the performance of a lens easily and reliably, by aligning the optical axis of the lens to be measured and the optical axis of a light source by means  of a position regulator and an angle regulator, and observing as well as picking up a  magnified image formed through a detachable transparent member and a magnification objective lens and the like.

Title: Vertical rotary valve
Inventor: KAMIYA AKIO
IPC: F16K3/08
Filed: 1981-03-27
Abstract: PURPOSE:To prevent crush of objects being transported by installing an upright cylindrical member solidly with the upper disc plate, forming a throat above the cylindrical member, and thereby eliminating touch of those objects with the stationary wall. CONSTITUTION:If disc plates 3, 4 turn in synchronization with th framing 2 and upper and lower pipings 7, 8, a cylindrical member 13 will turn together. Because this cylindrical member 13 is formed along the circumferential edges of the upper disc plate 3, its rotation involves a minute gap between the inside circumferential wall of the upper piping 7 and itself. When objects to be transported 9 are cast into this type of rotary valve 11, they 9 are led into the cylindrical member 13 in the whole amount under guidance of a throat tube 14. The objects 9 are further introduced to a compartment 1 in the framing 2 through a feed hole 5 of the plate 3. Consequently, the objects 9 are surely sent onto the plate 3, when they do not touch the inside circumferential walls of the upper piping 7, so that there is no risk of biting in.

Title: Needle type display device
Inventor: KOBAYASHI YUICHI
IPC: G01R7/06
Filed: 1995-03-06
Abstract: PURPOSE: To reduce electric current consumption of a step motor while realizing a smooth movement of an indicator by calculating moving distance of the indicator from present position information and indicating position information. CONSTITUTION: A moving distance calculating means 21b calculates moving distance of an indicator 11 from the present indicating information supplied at present to a step motor 14 and the indicating position information to be supplied in the next place. An electric power saving action practicing means 21a practices an electric power saving action only when the moving distance calculated by this means 21b is '0'. That is, since the electric power saving action is practiced after confirming that the indicator 11 does not move, a sudden movement of the indicator 11 caused by sudden arrival of the next driving signal is eliminated.  Since a period to perform the electric power saving action is regulated by a generating period of a timing signal sent out of a timer means 21i arranged to regulate the timing to calculate the moving distance, operational action to perform the electric power saving action can be reduced, and speed of processing can be increased.

Title: Bearing device of exhaust control valve
Inventor: UEDA HIDEAKI
IPC: F02D9/10
Filed: 1987-03-02
Abstract: PURPOSE:To avoid the occurrence of biased abrasion of a bush caused by carbon fine grains entering a bearing portion by making a contacting portion of a seal with a valve stem by graphite and freely loosely rotating the bush between the valve stem and a support member. CONSTITUTION:In a bearing device for valve stems 28a, 28b of an exhaust control valve 20, a bearing portion has two seals 58 and bushes 60 capable of loosely rotating. A sealing function with high heat-resistance can be obtained by the seals 58 mounted on the side contacting exhaust while a function of graphite 58b as a solid lubricant is used. Accordingly, there is no possibility that carbon fine grains in exhaust enter the bush 60 side, which avoids the generation of abnormal sound. Furthermore, since the bush 60 is capable of loosely rotating, even if the carbon fine grains enter between the bush 60 and the valve stem 28a or 28b to be bitten therein, a gap is left between the outer periphery of the bush 60 and a bearing plate 32 or 34 so that the bush 60 itself turns. Therefore, the bush 60 can be kept from biased abrasion.

Filed: 1982-03-23
Abstract: PURPOSE:To improve the performance of an information processor, by accelerating the processing speed of a conditional branch instruction when a simple arithmetic instruction and the conditional branch instruction are processed consecutively in a pipeline process. CONSTITUTION:A comparator CMP18 compares the data read out of a general- purpose register (GPR)6 with an operand data (ODR)5 given from a storage device. When the value of the data read out of the GPR6 is smaller than the value of the data of the ODR5, a signal LESS showing the value of a conditional code to be set by an instruction of comparison is set at 1. An AND gate 19c obtains an AND among signals COMP, COND and LESS, and an output signal BR of an AND gate 19c showing whether a branch is generated with a conditional branch instruction is set at 1 when the signal LESS is set at 1. Furthermore the signal BR produces a signal CBR showing that the processing is started for an instruction of the branching destination at the next time slot which is set at a time point when the processing of instruction proceeds to the next time slot.

Abstract: PURPOSE:To make it possible to accurately perform the sampling of an infrared interference optical signal corresponding to the position of a moving mirror during a time when the moving mirror moves many times, by measuring a time interval from the generation of a trigger signal showing that the moving mirror reached a specific state to that of the sampling signal succeeding thereto. CONSTITUTION:When a moving mirror 5 is moved to the right direction, infrared interference rays, laser interference beam and white interference light are respectively obtained from a detectors 8, 11, 16. The interference rays from the detector 16 are supplied to a trigger pulse generation circuit 23 having a reference level preset thereto and, when said interference rays came to reference level intensity, a trigger pulse is generated. The signal from the detector 11 receives wave form shaping by a wave form shaping circuit 21 to obtain a pulse signal. The trigger pulse signal is supplied to a counter 25 where the counting of the signal from a clock signal generation circuit 24 is started. The counting of the signal in the counter 25 is performed up to the point of time when the pulse from the wave form shaping circuit 21 succeeding to the trigger pulse is generated and the delay time corresponding to each value of the time up to generation is stored in a computer 19.

Abstract: PURPOSE:To elevate the quality of printing by making the rising of operation of a carriage slow when it is driven after a thermal head presses on a paper to prevent fouling due to rubbing of an ink ribbon at the start of printing. CONSTITUTION:To achieve a slow rising of the carriage, first, a CPU14 set time based on data contained in a ROM27 to be set on a timer 28. When the set time is reached, a carriage driving motor 4 is driven by one step. At the step S104, judgment is done whether the heating section is exceeded or not. While the accelerating section is still covered, a return is made to the step S101 and new data is read out of the ROM27 to set the time. Then, this step is repeated. When the accelerating section is exceeded, a shift is made to the step S105 to move the operation to a constant-speed control.
