Title: Method and device for forming center hole of disc molding
Inventor: SHIMOJO SHUNICHI
IPC: B29C45/26
Filed: 1997-02-25
Abstract: PROBLEM TO BE SOLVED: To prevent fins from being generated by moving a male cutter backward to slide the male cutter into contact with a center hole part with a gate formed by cutting after the gate is formed by cutting with the forward movement of the male cutter. SOLUTION: A center pin 32 is arranged with a center pin activating member 53 leaving a gap Z equivalent to a moving distance when a gate is formed by cutting. Even when a male cutter 31 recedes at the time of gate cutting, the center pin 32 does not move by the amount of the gap Z and retains its position as its is. Thus the male cutter 31 which has formed center hole H alone moves backward, while the center pin 32 advances, holding a spool molding part N. Fins crowed out into the sliding gap of the center hole part H with the gate formed by cutting following the forward movement of the male cutter 31, are drawn into the inner periphery of the center hole H simultaneously with the retreating (r) of the male cutter 31 to eliminate the generation of fins.

Filed: 1978-05-19
Abstract: PURPOSE: To surely and quickly break a circuit, by combining relays and a thyristor with each other as circuit breaking elements, mechanically opening the circuit by the relays and accelerating the breaking with the thyristor.  
     CONSTITUTION: A current signal from a shunt 11 is compared with a setpoint by a current comparator 6. When the current signal has exceeded the setpoint, an overcurrent detection signal is produced and applied to a driving signal generator 8 to generate a protector driving signal. This driving signal is applied to a thyristor driving circuit 9 and a relay driving circuit 10. The thyristor driving circuit supplies a trigger voltage to the gate of the thyristor 3 to turn it on. The relay driving circuit energizes the coils of the relays 4a, 5a to open contacts 4b, 5b, 5c. Before the  opening of these contacts, a power supply unit 1 is short- circuited by the turn-on of  the thyristor 3 to prevent an overcurrent from flowing to a load 2.

Title: Announcing device
Inventor: MIYAHARA YASUO
IPC: G11B20/00
Filed: 1980-05-06
Abstract: PURPOSE:To always ensure a transmission of a recorded message to the hearer from the start, by adding an output circuit in accordance with a selection of channel to a device which is used for the talkie service or the like of a telephone exchange. CONSTITUTION:A magnetic drum 1 rotates interlocking with a cam 6, and the hearer is connected to an output OUT-1 when the cam is at the position shown in the diagram. The output of an amplifier 3-1 is supplied to the aural output of a channel selector 4 when a start input E-1 arrives at the earth. Then the cam 6 starts rotations, and a reproducing head 2-I starts a reproduction of the recorded message. Thus the hearer of the OUT-1 can hear the message from the first. With a further rotation of the cam 6, the hearer is connected to an output OUT-2. When a signal arrives at a start input E-2, only the switch 7-III is closed to apply the output of an amplifier 3-III to the output of a channel selector 5.

Title: Aromatic composition
Inventor: ONISHI KAZUYUKI
IPC: A61K8/18
Filed: 1992-02-13
Abstract: PURPOSE:To obtain an aromatic composition capable of exhibiting extremely excellent retaining effect on fragrance having relatively high volatility and simultaneously suitable for practicality without giving tackiness even in blending with perfume or a fragrance product such as cologne. CONSTITUTION:The aromatic composition is obtained by blending a chain or cyclic dimethylpolysiloxane of formula I or formula II whose vapor pressure at 100 deg.C is 0.1-300mgHg, preferably 0.1-15mgHg, used as a retaining ingredient with an aromatic component in an amount of >=10 pts.wt. preferably >=100 pts.wt. based on 100 pts.wt. aromatic component. The dimethylpolysiloxane is suitable for practicality, because the compound is readily dissolved in a fragrance product system such as perfume and cologne and stably exists and simultaneously can be used for various purposes because the compound has good feeling of use and is almost odorless even when blended with these fragrance products and the retaining effect of the perfume having high volatility can long be expected.

Title: Optical card device
Inventor: SAITO AKITO
IPC: G11B7/00
Filed: 1989-03-14
Abstract: PURPOSE:To prevent a tracking servo from being released even when a defect on an optical card exists on a stop position and to effectively hold an objective track by providing the title device with a carrying control means for controlling a stop position on relative movement between an optical card and an optical head to shift the stop position when it is deflected from the objective track. CONSTITUTION:When the stop position is shifted from an objective track due to a defect on the optical card in the vicinity of the stop position, the stop position on the relative movement is controlled through a carrying means to be relatively moved. A constant speed position detecting circuit 41 decodes the output of an up/down counter 25E and detects the constant speed carrying position of a shuttle. At the time of detecting shift from a track to be read out, a controller 28 seaks the objective track again and sends a count inhibiting signal to a count inhibiting circuit 42 at a next carrying the shuttle. The stop position of the optical card 11 against the optical head 21 is shifted to stop the optical card 11 with a deviation from the defect. Consequently, the objective track can be held without releasing the tracking servo.
