Title: Creep control device for toroidal type continuously variable transmission
Inventor: SHIMAMOTO MASAO
IPC: F16H15/38
Filed: 1987-02-18
Abstract: PURPOSE:To perform mechanical and specified control of creep torque during idle running, by providing a hydraulic control valve which exerts a deferential pressure between an oil chamber on the positive drive side, facing the rotation direction of an input disc, and an oil chamber on the reverse drive side positioned reverse to aforesaid oil chamber against the spring load of a spring. CONSTITUTION:During idling, a duty ratio D of a solenoid valve 171 is low, and an output oil pressure P5 is guided from a creep control valve 160 to a starting clutch 40. Namely, since the output oil pressure P5 of a creep control valve 160 is controlled such that the more a difference between an oil pressure P1 of positive drive oil pressure chambers 75 and 76 and an oil pressure P2 of oil chambers 74 and 77 on the reverse drive side is increased, the more an output oil pressure P5 of a creep control valve 160 is decreased, with the decrease in input torque, transmission torque of the starting clutch 40 is increased, and creep torque is automatically regulated to a specified value responding to the magnitude of the spring load of a spring 161. This constitution enables maintenance of creep torque to a normally specified value irrespective of unevenness in the spring load of the return spring of the starting clutch 40, unevenness in its surface pressure, and a fluctuation in a friction factor due to a change in an oil temperature.

Title: Polystyrene resin bead foam container for food, and foaming polystyrene resin particle for food container
Inventor: OHARA HIDEKAZU
IPC: B65D65/02
Filed: 1999-02-15
Abstract: PROBLEM TO BE SOLVED: To specify the elution of a styrene dimer and a styrene trimer in a resin into a heptane by manufacturing a foam container out of a polystyrene resin in which methacrylic ester is co-polymerized. SOLUTION: A monomer component to be co-polymerized with a polystyrene resin includes a methacrylic ester such as a methacrylic methyl and a methacrylic ethyl. The copolymerization quantity is 10-40 wt.%, preferably 10-25 wt.%. If the component is 10 wt.% or under, the effect to reduce the elution of the styrene dimer/trimer becomes small, while the formability is degraded if the component is not less than 40 wt.%. The suspension polymerization or bulk polymerization can be adopted for the polymerizing method, but the suspension polymerization is preferable from the viewpoint of reducing the quantity of styrene dimer/trimer in the resin. In a foam container formed of this polystyrene resin, the elution of styrene dimer/trimer into heptane compared to the soup of instant noodle is 5 ppb or under.

Title: Heater board for electric heater
Inventor: TAMAI MASAYUKI
IPC: H05B3/10
Filed: 1994-02-08
Abstract: PURPOSE:To heighten the rigidity of a heat generating band and prevent irregular partial deformation due to electricity application and heating by forming a continuous rib strip extruded from one face to the other face in the heat generating band of a heat generating plate body along the winding of the band. CONSTITUTION:A heat generating plate body 1 is formed by punching a stainless steel plate by pressing process. A heat generating band 2 with a narrow width is laid in rows in one plane in the way the band winds to form symmetric shapes while having parts near electricity supplying terminals 3, 4 between them and to form a circular shape as a whole. In the heat generating plate body 1, the parts 7b, 7c, which compose both right and left sides, of the heat generating band 2 and the part 7a, through which the parts 7b, 7c are connected, form winding shapes in the same direction and only the parts near the electricity supplying terminals 3, 4 form winding shapes in the direction at right angles to the direction of the parts in right and left sides. The parts 7 near the electricity supplying terminals 3, 4 are formed with a wide width in order to provide the parts with higher strength than other parts and that results in lower electric resistance than that of other parts, and consequently the quantity of heat generation in the parts is lowered and the heating temperature in all the parts is made uniform.

Title: Detecting circuit for minimum position of audio signal level
Inventor: HIRATA HITOSHI
IPC: G01R19/04
Filed: 1983-03-03
Abstract: PURPOSE:To obtain a detecting circuit of simple constitution which detects the minimum level position of an input audio signal with superior operation stability by detecting a minimum level position signal indicating a zero-cross point of time close to the minimum position of a peak level at a bottom of the envelope of the input audio signal. CONSTITUTION:An address latch 39 holds and outputs the output address value of an address counter 5 according to the rising of a zero-cross pulse, so an address latch 42 is supplied with the same address value from the address latch 39 from one zero-cross point of time in a level falling period of the audio signal to the next zero-cross point of time. Consequently, the address latch 42 holds and outputs the output address value of the address latch 39 according to the rising of a detection pulse, so the output address value of the address latch 42 is the signal of a zero-cross point of time close to the minimum position of a positive beam level at a bottom of the envelope of the audio signal, i.e. minimum level position signal. Therefore, the address value at the zero-cross point B is outputted from the address latch 42 between the rising point A of the detection pulse and the next rising point.
