Title: Automatic thread conditioning device for sewing machine
Inventor: MATSUBARA KENJI
IPC: D05B69/10
Filed: 1989-07-26
Abstract: PURPOSE:To feed out the upper thread of an automatic thread conditioning device neither too much nor too little even when a needle bar is set in a released state by providing a control means to control the feeding-out of the thread based on the amount of the thread to be fed out, which is calculated by a thread feeding-out amount calculating means, at the time of release while the needle is in the released state. CONSTITUTION:When a deciding means X1 decides that the needle is set in the released state to cancel likage with a main shaft, a release time thread feeding-out amount calculating means X2 calculates the amount of the thread to be fed out from the amount of working cloth to be fed out at that time and the amount of the needle to be oscillated. While the needle is set in the released state, the feeding-out of the thread is controlled by a control means X3 based on the amount of the thread to be fed out which is calculated by the release time thread feeding-out amount calculating means X2. As a result, even when the needle bar is set in the released state and only the feeding of the working cloth is executed, the thread is fed out neither too much nor too little.

Title: Lens array
Inventor: AOYAMA SHIGERU
IPC: G02B27/00
Filed: 1988-08-04
Abstract: PURPOSE:To remove stray light and to improve resolution by forming light shielding masks on the other face of a transparent base and forming comparatively small apertures allowing the transmission of light on parts of the mask corresponding to parts around the optical axis of the lens. CONSTITUTION:The light shielding masks 2 are formed on the face opposite to the face of the transparent base on which a lens array is formed. Since the apertures 4 having a diameter smaller than the diameter of each lens 3 are formed on the center parts of the optical axes of respective lenses 3, light beams from respective points of an image face 7 are concentrated only by the corresponding lenses 3 and their images are formed only on their corresponding CCD elements 6. Since unnecessary stray light can be shielded by the masks 2, respective points on the image face 7 correspond to respective CCD elements 6 at the ratio of 1 to 1 and the resolution of an image formed in each CCD element can be improved.

Inventor: TABUCHI KENJI
IPC: G03G15/08
Filed: 1987-07-31
Abstract: PURPOSE:To develop a latent image on a photosensitive body without contacting by forming the surface of a sleeve provided oppositely to an electrostatic latent image carrier by using a vibrating dielectric layer. CONSTITUTION:The vibrating sleeve 2 is provided nearby a photosensitive body 100 and formed of a thin conductive roll 8 which has a dielectric layer on its outside surface, and it rotates while vibrating finely. This vibration is sent to an ultrasonic vibrator 10 which contacts a rotary driving shaft 9 to vibrate the surface of a conductive roll 8. Then toner moves onto the vibrating sleeve 2 according to the bias between a magnetic roller 3 and the vibrating sleeve 2 and reaches an area nearby the sleeve 2 and photosensitive drum 100 and the electrostatic latent image is developed while the toner is attracted to the side of the photosensitive drum 100 at its image part and to the side of the sleeve 2 at its background part. Consequently, the development is performed without contacting.

IPC: H03M1/36
Filed: 1988-08-03
Abstract: PURPOSE:To realize high resolution with simple circuit constitution and to attain high speed digital code conversion by changing the resolution according to the quantity of an analog input signal. CONSTITUTION:Comparators 13, 14 discriminate which area an analog input voltage Vin enters and a reference voltage being an element to obtain a comparison voltage of plural comparators C1-C63 is switched according to the result by a multiplexer 15 and a bit shift circuit 26 shifts bits of a digital code outputted from a code converter 11. That is, when the analog input voltage Vin is small, the reference voltage is switched to a small value to increase the resolution, and the digital code outputted from the code converter 11 is shifted toward the low-order bit accordingly. Thus, high resolution is obtained by simple circuit constitution and digital code conversion is implemented at a fast speed.

Title: Load falling preventer circuit of load lifting gear
Inventor: NAGAO YOSHINOBU
IPC: B66B5/02
Filed: 1992-07-22
Abstract: PURPOSE:To prevent any possible danger that braking torque goes down due to trouble in a braking means of a load lifting gear and a load might fall as making it unsupportable from occurring. CONSTITUTION:When an electric motor 4 driving a load lifting gear 5 is stopped and a braking means is operated, supporting a load 7, if braking torque goes down for some reason or other, this load 7 falls down, but with this falling of the load 7, the motor 4 is rotated, and thereby a speed detecting means detects rotational speed in the motor 4. Since a speed command value is zero in time of issuing a stop command signal, if a fact that a difference between this speed command value and the speed detected value has come to more than the specified value is detected by a speed discord detecting means, it is judged as something wrong with the damping means, thus such a command as operating it at zero speed is given to the motor 4. With this constitution, the motor 4 generates a torque holding the load 7, so this load 7 is preventable from falling.

Title: Drive controller of stepping motor
Inventor: TAKAISHI KAZUAKI
IPC: H02P8/16
Filed: 1983-10-19
Abstract: PURPOSE:To improve the rotary drive responding characteristic of a stepping motor by removing an unnecessary exciting current for holding a motor. CONSTITUTION:An exciting current for holding a motor is flowed for the prescribed period as shown by hatched portions (h). This is inserted only to the head portion of the data signal, but not inserted among rotary drive data D1, D2, D3. The motor holding function is provided in the exciting current for absorbing the vibration designated by T2. Accordingly, as compared with the conventional controller in which the exciting current for holding the period T1 among the data signals D1, D2, D3, the time characteristic of rotary drive response can be improved, and since the time for flowing the exciting current for holding the motor can be shortened, the power consumption can be reduced.
