Title: Small-sized motor
Inventor: MURAKITA WATARU
IPC: H02K13/00
Filed: 1980-03-31
Abstract: PURPOSE:To prevent thermal deformation of a leaf spring in a small-sized motor  and prolong the lifetime of the motor by connecting the back of a brush to the terminal of a power source with a slack conductor when the brush is mounted at the  end of a conductive leaf spring connected to the terminal of the power source, thereby reducing the current flowing through the leaf spring. CONSTITUTION:When a brush 3 is mounted at the end of a conductive leaf spring 2 electrically connected to the terminal 1 of a power source and pressed on the surface of a commutator, the terminal 1 of the power source is further connected electrically to the back of the brush 3 with a slack conductor 4. The conductor 4 is sufficiently slackened so as not to eliminate the pressure of the brush due to the leaf spring 2, and preferably formed of twisted wires. Thus, the current flowing through the leaf spring 2 can be reduced even in the case of low voltage and high current, the thermal deformation due to Joule heat can be prevented, and the lifetime of the motor can be prolonged.

Title: Abrasive cloth sheet structure
Inventor: IDOTA TAMOTSU
IPC: B24D11/00
Filed: 1984-03-05
Abstract: PURPOSE:To gradually reduce a protective layer with the progress of grinding without the grinding being hindered, and as well to prevent an alumina abrasive from coming off to enhance the grinding ability of the abrasive, by providing such an abrasive that a special protective layer is formed over an abrasive which is adhered to a substrate. CONSTITUTION:A sintered abrasive 1 having an averaged particle size of about 100-600mu having alpha-alumina as a main component is adhered to a substrate 2 through the intermediary of a first adhesive layer 3. Then, a second adhesive layer 4 is formed on this abrasive 1 and the first adhesive layer 3, and thereafter, a protective layer 5 is formed on this second adhesive layer 4. At this stage, the protective layer 5 is composed of a mixture of a synthetic resin and an inorganic filler having less than 30mu of averaged particle size. The weight ratio of inorganic substance and the solid part of the synthetic resin is adjusted to a value of about 1.5-32.3. This protective layer 5 is reduced with the progress of the grinding to make satisfactory the holding force of the abrasive so that the coming-off of the abrasive particle is prevented.

Title: Interruption circuit
Inventor: YABUKI NOBORU
IPC: G06F1/24
Filed: 1988-02-25
Abstract: PURPOSE:To prevent unnecessary initial setting and to eliminate a trouble or an accident by causing a CPU to have function to output the executing condition of an interruption processing program to an external part in the shape of an output signal and providing a circuit to prohibit the input of a reset signal to the CPU with the output signal. CONSTITUTION:An external output terminal OUT of a CPU40 is controlled by the interruption processing program and when the CPU40 executes the interruption processing program, the external output terminal OUT goes to H. Thus, an output side N3 of a NAND gate 72 goes to H and a reset input terminal inverting RES goes to non-active. Accordingly, the input of a reset signal 60S is prohibited and the input of an interrupting signal 50S gets priority. When the interrupting signal 50S and reset signal 60S are simultaneously generated, the interrupting signal 50S is inputted top the CPU40 with priority. Namely, when a power source voltage is lowered and a system is instable, data are saved without fail and emergency stop is executed. Then, the causes of the trouble or accident are erased and the recovery work of the unnecessary initial set is eliminated.

CONSTITUTION:A message sent from the center 1 unidirectionally to the terminal controller 2 is outputted to a terminal equipment 3 via the terminal controller 2. If a message cannot be received for the terminal equipment 3 due to any cause, the terminal controller 2 stores the message and stores its state.

Abstract: PURPOSE: To make the home position stopping of a movable reflecting mirror sure by elastically contacting the movable reflecting mirror to a stopper pin which defines its stop position and cutting off the energizing of the electromganetical driving device of the mirror at the time when it contacts the same.  
     CONSTITUTION: Energizing of a motor is cut off in the final end position of the reciprocating oscillation of a drive lever 17 by the reciprocating turning of a gear 18. To this end, a pin 25 is provided to the free end of the arm 17c of the drive lever 17 and said pin 25 cooperates with the switches 26, 27 fixed to the machine frame. When the drive lever 17 oscillates a movable reflecting mirror 6 to the normal projecting position by a spring 19a, the pin 25 actuates the switch 26 which in turn causes the motor to be deenergized by way of a control circuit at the time when a holding frame 11 elastically contacts a stopper pin 12. When the mirror 6 is oscillated to the variable power position and the holding frame 11 elastically contacts a stopper pin 13, the switch 27 is actuated by the pin 25 to deenergize the motor. In this way, the home position stopping of the mirror is surely accomplished.

Title: Manufacture of stainless clad aluminum strip
Inventor: UEHORI YUJI
IPC: B23K20/04
Filed: 1987-02-27
Abstract: PURPOSE:To efficiently obtain a stainless clad Al strip having superior workability by charging Al powder into a hopper formed with stainless steel strips, solidifying the Al powder confined in the space between the steel strips by pressing with rolling rolls and carrying out heating and rolling. CONSTITUTION:Al powder A is charged into a Y-shaped hopper formed with stainless steel strips S as shell materials, guide rolls G and rolling rolls M1.

Filed: 1989-02-23
Abstract: PURPOSE:To finely adjust the transmission wavelength of an interference filter by providing an angle adjusting means which adjusts the angle of the interference filter to the optical path of a photodetection system. CONSTITUTION:The transmission wavelength characteristics of the interference filter 4 vary with the angle theta of incident light and the transmission wavelength characteristics when reflected light R is made incident at angles thetaA=90 deg., thetaB and thetaC vary as shown in a graph.
