Title: Driving circuit for step motor
Inventor: TERAI HARUO
IPC: H02P8/14
Filed: 1981-02-24
Abstract: PURPOSE:To reduce the cost of a step motor by using an AC power source as the power source for the motor as it is, thereby eliminating a transformer and a large capacitor. CONSTITUTION:When a power switch 2 is closed, a capacitor 10 is charged in half wave to form a DC power source. A zero cross pulse generator 8 generates a pulse in the vicinity of zero voltage of the waveform of the power voltage. This pulse output is inputted to a counter 7, and is counted for odd numbers, and a pulse is then generated at odd pulses, for example, at each 3 pulses. A transistor 6 is driven by the output to flow a current to the gate of a triac 3, thereby triggering the triac 3. Accordingly, the half wave of the AC power source is alternately applied in positive and negative to the coil 4 of the step motor, and the step motor is rotated at every constant angle synchronously with the pulse.

Title: Communication method among processors for electronic exchange
Inventor: HIRAIWA KENJI
IPC: H04Q3/72
Filed: 1986-02-12
Abstract: PURPOSE:To dissolve the increase in the load factor of a processor and to enhance a processing capacity by providing a status register for concentrating the state of a communication processing hardware between the processors. CONSTITUTION:Since highways HW0-HW7 are used in common by plural terminals T, so that when 256 terminals T are, for instance, provided for the respective highways HW0-HW7, if the presence/absence of the receiving data of the highways HW0-HW7 is not monitored or not transmitted/received with the cycle of about 4msec, there is produced a delay incapable of communicating in a terminal control processor TC side. However, the status register for displaying the receiving state is constituted in a tree construction, thereby, the dynamic step of a monitor program for the receiving state is deleted and the processing capacity can be prevented from being deteriorated.

Title: Toilet seat unit
Inventor: MIYAMOTO HIROOMI
IPC: A47K13/30
Filed: 1999-02-04
Abstract: PROBLEM TO BE SOLVED: To minimize the power consumption by providing a heat insulating member, heat reflecting member or high-heat conductive member within a space part of a toilet seat. SOLUTION: A heat insulating material 7 enclosed by a heat reflecting member 8 such as aluminum foil is adhesively provided on a toilet seat bottom plate by use of an adhesive. The heat insulating material 7 is not made into a similar form as the seat bottom plate but used as a divided member. Thus, the waste of material in the working of the heat insulating material can be eliminated to improve the working property in the adhesion to the seat bottom plate. Further, the protruding part of the cushion part of the seat bottom plate can be avoided to prevent the reduction in working property by unevenness. The aluminum foil 8 reflects the radiation heat from a heater 5 to suppress the wasteful heat transfer to the seat bottom plate. The heat insulating material 7 suppresses the wasteful transfer to the seat bottom plate of the heat conducted by the internal air of the hollow structure.  Accordingly, the power consumption can be suppressed to save the energy.

Filed: 1979-03-09
Abstract: PURPOSE: To obtain the electrostatically flocked product which is rich with surface variations and does not permit seeing-through of flocking base material surface by fusion bonding an temporally twisting thermoplastic synthetic fiber multifilaments, then electrostatically flocking.  
     CONSTITUTION: While thermoplastic synthetic fiber multifilaments are being strongly twisted to S twist or Z twist, they are heated to the temperature of the softening point to melting point of these fibers and are fusion-bonded, after which they are untwisted. Next, these fusion-bonded multifilaments are subjected to dielectric treatment so that piles are charged by high voltage electric fields and fly, after which they are dried at about 100°C or less. Thence, the piles after the dielectric treatment are electrostatically flocked on the base material surface having been coated with adhesive agents in the high voltge electric field. Following to this, the electrostatically flocked piles are crimped, at the same instant of which the adhesives are set. As a result of this, the resultant piles are crimped to curl-form by the heat treatment after the flocking and show the appearance rich with surface changes entirely diferent from those of conventional flocked products, thus the flocked products of Brussels appearance may be obtained.
