Title: Method of manufacturing cast resin molding with through hole and article thereof
Inventor: NAKABASHI SUMIO
IPC: B29C39/26
Filed: 1991-04-19
Abstract: PURPOSE:To obtain a cast resin molding capable of expecting sufficient brightness as back-lights by piercing a rigid core material into a cell-set (mold frame), and injecting a cast resin material so as to be cured therein. CONSTITUTION:After a rigid core material is pierced into a cell set (mold frame), which is coated in a not-integrated manner with a low frictional hydrophobic material being inactive to polymerization-hardening reaction, a cast resin material is injected into the cell set and a heat treatment is effected for polymerization-hardening. In the next place, the core material and coating material are extracted from the hardened body. In this instance, it is preferable to employ a two-stage extracting method wherein the core material is pulled out at first at a high temperature state immediately after the heat treatment and then the remaining coating material is extracted after the completion of an annealing treatment. A cast resin molding 1 with through hole obtained in this manner has a penetration hole 2 of 6mm in its inner diameter being parallel to both upper and lower peripheries and, by inserting the linear light source of a cold-cathode tube or the like into the hole 2, it is utilized as an edge-lighting transparent board being extraordinarily excellent in brightness.

Abstract: PURPOSE: To eliminate the occurrence of excessive overshoot even though the speed of the head becomes excessive during the track followup operation by stopping the input of a head positional error signal to an integrator at the time when the speed of head is out of the specified range. CONSTITUTION: A switch 26 provided between a circuit 14 for detecting head positional error and the digital integrator 28 is in the OFF state when the signal of excessive head speed is received from a circuit 24 for detecting head speed, and the head positional error signal Yn is not supplied to the digital integrator 28.

Title: Switching power-supply circuit
Inventor: SATO MITSURU
IPC: H02M3/28
Filed: 1995-05-17
Abstract: PURPOSE: To obtain a switching power-supply circuit which prevents an output voltage from being raised abnormally by a method wherein, when a load is reduced and the magnitude relationship between a status signal value and a limit value has become reverse to normal, a charging and discharge speed is reduced and the oscillation frequency of a synchronizing signal is lowered. CONSTITUTION: When a load is cut off or reduced and an output voltage Vo is raised abnormally, the signal value of a voltage detection signal Sv received by an amplifier circuit 40 becomes less than a limit value, an amplification output becomes negative, and a diode 43 turns on. As a result, an oscillation circuit 10 receives an output from the amplifier circuit 40, and the base potential of a transistor 13 is lowered. Then, the reference current of a current mirror circuit 12 flowing to an emitter resistance 14 is reduced, a charging current flowing to a capacitor 11 from the follower side is reduced, a charging speed is lowered, and the oscillation frequency of the synchronizing signal Sr of the oscillation circuit 10 is lowered.  On the other hand, when the output voltage Vo is raised abnormally, the on-time of a switching means 1 is a nearly constant minimum time, and the output voltage can be reduced according to a drop in the oscillation frequency of the synchronizing signal Sr. As a result, it can be limited to a tolerance or lower.

An integrator 48 integrates the signal f2 to produce a triangular signal Vr and a difference amplifier 49 outputs the difference signal VD between a reference voltage + or -ES1 and a reference voltage V, 2 A comparator 50 compares the signal Vr with the signal VD to produce a signal Vsc for controlling a switch SW to sustain the exciting current If at a constant level. On the other hand, a timing circuit 51 receives the signals f2, fn a samples the flow rate signal SMP having a predetermined sampling width in synchronism with the signal f2 prior to next signal.
