Title: Mounting structure to shaft of electromotor in rotation detector
Inventor: EBARA YASUO
IPC: H02K11/00
Filed: 1986-03-14
Abstract: PURPOSE:To provide the electromotor shaft mounting structure of a rotation detector requiring no shaft joint, easy to mount and having good mount accuracy, by mounting an electromotor shaft to a hollow rotary shaft equipped with rotary parts by inserting the same in said shaft and mounting a non-rotary part to an electromotor body part through a spring. CONSTITUTION:When an electromotor shaft 14 rotates, the hollow shaft 24 mounted thereto rotates and a rotary slit 28 rotates. The non-rotary part of a light detection part containing a light emitting element 42, a fixed slit 34 and a light receiving element 36, that is, the unit of a slit gauge 33 is supported concentrically by the hollow shaft 24 in a freely rotatable manner through a ball bearing 30. Because the non-rotary part is connected to the end part of an electromotor body part through flexible mount fittings 21, said non-rotary part is not rotated and, if there is displacement in the electromotor shaft 4, can absorb said displacement and the lowering in accuracy or damage is prevented.

Title: Production of cephapirin
Inventor: YAHAGI KAZUHIRO
IPC: C07D501/34
Filed: 1980-04-28
Abstract: PURPOSE: Silylated 7-(α-bromoacetamide)cephalosporanic acid is made to react with 4-mercaptopyridine, followed by desilylation to give the titled compound used as an antibiotic economically in high yield.  
     CONSTITUTION: A compound of formula 3 or its salt is made to react with a silylating agent, preferably N,N-bistrimethylsilylacetamide to give a novel compound of formula 4 [R is H, Si(CH 3 ) 3 ]. The compound of formula 4 is made to react with another compound of formula 5 to form a compound of formula 6. Then, the compound of formula 6 is desilylated with water or methanol to give cephapirin of formula I: the chemical name is 7-[α-(4-pyridylthio)acetamide]cephalosporanic acid. Since the product is obtained through the compound of formula 4 that has high solubility, each reaction can be effected under neutral conditions to prevent the β-lactam ring from being cleaved, thus giving high-purity objective compound in high yield.

Abstract: PURPOSE: To simplify the usually troublesome assembling and adjustment of a printing head and reduce the size and cost of the printing head by a method wherein plural print wires and the armature for driving them are rendered to be a unit integral with a single leaf spring common to them.  
     CONSTITUTION: A printing head is assembled as follows: a spacer 9 is placed on a magnet assembly; an armature 9 and a wire assembly are placed on the spacer 6; a guide frame 10 fitted with a pin guide 11 is arranged to cover the armature 9 and the wire assembly, allowing a print wire 8 to pass through the pin guide 11; and the guide frame 10 is fixed to the magnet assembly with screws. With the magnet coil 4 supplied with current, the coil 4 develops a magnetic field to cancel the field of a permanent magnet 3, and a print wire 8 is driven forward attending to the return motion of the split segments of a lead spring 7. Accordingly, selective supply of current to the magnet coil 4 results in printing of a desired dot pattern on the column.

Title: Stabilization device for dot position accuracy of printer
Inventor: KONAKA TOSHIO
IPC: B41J2/455
Filed: 1991-03-20
Abstract: PURPOSE:To prevent recording dots from shifting in position owing to an increase in thermal expansion even when light emitting elements are used continuously for a long time by controlling the quantity of light according to the detected value of the quantity of the light from the light emitting elements. CONSTITUTION:When there is no thermal expansion, a light beam is made to reach an image formation surface through the center of the light emission surface of an LED array substrate 41 and the opening part 43a of a mask surface 43 and its light image is formed on the surface of a photosensitive drum 45. The image formation surface is charged electrostatically and uniformly in advance and the latent image is formed. When there is thermal expansion, unnecessary light except at a prescribed position on the LED array substrate 41 is cut off by the mask 43. Then the transmission of a storage signal to some of the light emitting elements 42 corresponding to light receivers 47 irradiated with the light beam among storage elements of a light reception register 46 is cut off, so the corresponding light emitting elements 42 on the LED array substrate 41 turn off irrelevantly to a recording signal. Consequently, excessive thermal expansion is suppressed and the dot position shift is eliminated, so that no color slurring is caused.

IPC: G06T1/20
Filed: 1979-05-10
Abstract: PURPOSE:To enhance the throughput by producing the overflow alarm signal prior to the stack overflow detection of the output buffer memory with every processor in case the processing time differs for each processor forming the array. CONSTITUTION:Plural units of processor 1 which secure the operation of the array processor for the whole unit are connected to corresponding stack overflow alarm signal generating circuit 2 via signal lines 17-19. And each processor 1 is connected in parallel to input data transfer destination processor selection circuit 4 via information lines 11 and 12 or to array processor lock signal generating circuit 3 connected to circuit 4 and via signal line 15. Then circuit 2 is also connected to circuit 3 via signal lines 26 and 28. Thus the processor controller is formed. In such way, the unprocessed input data within the processor and due to the stack overflow can be done even in case the processing time differs for each processor 1. Thus the software process can be facilitated when the processing is started again.

Filed: 1999-03-05
Abstract: PROBLEM TO BE SOLVED: To easily detect the width of a luggage with a relatively small number of sensors by arranging a plurality of article sensors by varying their detecting lines against a conveyor and detecting the width from the difference between time intervals when luggage detecting signals are turned on. SOLUTION: Article sensors PH1 and PH2 are arranged astride a conveyor 6 by varying their detecting lines. For example, the sensor PH1 is arranged with its detecting line perpendicular to the transporting direction of the conveyor 6 and the sensor PH2 is arranged with its detecting line at an angle α of, for example, 15 deg.-60 deg. from the transporting direction of the conveyor 6 so that the sensor PH2 may detect the width W of a luggage 8 with high accuracy even when the luggage 8 does not have a rectangular parallelepiped shape. The width W of the luggage 8 is found from a formula, Ltanα=W (where, L represents the transporting distance of the conveyor 6 until the sensor PH1 is turned on after the sensor PH2 is turned on).

Abstract: PURPOSE:To obtain a preferable sealing state without sink-mark at the time of sealing resin by forming a cutout at part of the resin coated on the outer edge of a plate for forming a cap, and sealing it with the cap. CONSTITUTION:The outer periphery of a flat plate 1 formed of glass, ceramics, metal or the like is covered in the same width with resin 2, and cutouts 7, 7' are formed at the centers of the short sides. The cap 1 is overlapped on a ceramic substrate 4 which places a semiconductor element 3, a load is applied thereto by a clip or the like, and heat treated to obtain a preferably sealing state without sink-mark. This is because, even if air in a cavity is expanded at temperature rise, air is leaked externally until the cutouts 7, 7' are blocked, thereby reducing an increase in the internal pressure.
