Title: Photographic film cartridge
Inventor: KATAOKA HIDEAKI
IPC: G03B17/26
Filed: 1990-05-28
Abstract: PURPOSE:To keep the output torque of a spool at the time of rotating a film roll small and to smoothly feed a film by making ribs discontinuously formed on the inner wall of a cartridge main body discontinuously contact at plural spots on entire periphery of the film roll. CONSTITUTION:The cartridge main body 5 is constituted of an upper main body 5a and a lower main body 5b, and two ribs 8 and 8 and short ribs 9 and 9 are integrally formed on the inner wall of the upper main body 5a and the inner wall of the lower main body 5b, respectively. The ribs 9 and 9 are formed also at a position which leads to a port part 6b, and a tip separation pawl 10 is integrally formed on one rib 9. The ribs 8 and 9 contact with the outermost periphery of the film roll 4 on a little inner side of perforation trains formed both side edges of the film 2 so as to prevent winding of the roll 4 from being loosened with respect to the spool 3 when the spool 3 rotates clockwise. The contacting range of the ribs 8 and 9 with the roll 4 is made discontinuous in the rotating direction of the roll 4.

Title: Level shifter
Inventor: OBATA HIROYUKI
IPC: H03K5/02
Filed: 1981-09-01
Abstract: PURPOSE:To obtain a stable input/output characteristics even if the threshold voltage of an MOSFET is fluctuated, by constituting the circuit so that the fluctuation of the logical threshold voltage of an inverter circuit due to the fluctuation of the threshold voltage of the MOSFET is cancelled. CONSTITUTION:Since an MOSFET TR2 shows a high resistance, an MOSFET TR4 is made conductive for VDD-2VT>0. VDD is the power source voltage, and VT is the threshold voltage. When an input signal VIN is applied, such potential is generated at a point 2 that the same current is flowed to MOSFETs TR3 and TR4. Since the potential at a point 1 becomes lower when the threshold voltage VT of the MOSFET TR3 is fluctuated to become higher, the fluctuation is cancelled at the point 2, and the circuit is not affected by the fluctuation of the threshold voltage VT.

Title: Sound synthesizing device
Inventor: NAKAJIMA YASUYOSHI
IPC: G10H7/08
Filed: 1998-05-02
Abstract: PROBLEM TO BE SOLVED: To designate and control the synchronous sounding with other channel by controlling a sound signal generating means based on the sounding designating information supplied from the generating means of sounding designating information to other channels. SOLUTION: A channel synchronizing operation flag RBP is used for channel synchronizing operation. Since RBP=0 in the channels CHk+1, CHk+2, musical sound signals are independently generated in the channels CHk+1, CHk+2, respectively, based on own key-on signals KONk+1, KONk+2, pitch frequency numbers FNUMk+2, FNUMk+2 and other parameters. Since RBP=1 in a channel CHk+3, it is controlled so as to synchronize in sounding with the previous channel CHk+2. Similarly, as to the remaining channels, synchronization or asynchronization in sounding with the adjacent channel is controlled.

Title: Succinic acid peroxide composition
Inventor: DEMACHI TAKUYA
IPC: C07C407/00
Filed: 1982-08-10
Abstract: PURPOSE:To provide the titled composition capable of keeping high safety, stability and fluidity in low-temperature storage, having excellent handleability, and useful especially as a catalyst for the emulsion polymerization of tetrafluoroethylene, etc., by compounding a specific amount of water with succinic acid peroxide. CONSTITUTION:The succinic acid peroxide can be prepared by conventional process, i.e. by the reaction of succinic anhydride with hydrogen peroxide in the presence of an alkali.

When the water-content is <10wt%, the composition is sensitive to impact, and cannot be handled safely, and when the water content exceeds 25wt%, the fluidity of the composition becomes poor. The water-content of 12-20wt% is especially preferable in view of balanced fluidity and safety. EFFECT:There is not the least adverse effect in the polymerization reaction.
