Inventor: SUGAWARA HIROSHI
IPC: B29K105/08
Filed: 1991-11-22
Abstract: PURPOSE:To efficiently produce a fiber reinforced thermoplastic resin pipe excellent in interlaminar bonding strength even when first and second reinforced layers are formed by employing an inner core system. CONSTITUTION:A double-layered pipe consisting of an inner thermoplastic resin layer B3 and a first reinforced layer A3 is introduced into an inner core 6c in such a state that it is held to the temp. range from the softening temp. of the matrix resin constituting the first reinforced layer A3 to below the m.p. thereof and a fiber composite C1 is wound around the inner core 6c at the outside position thereof at temp. below the m.p. of the matrix resin to form a second reinforced layer C2. By this constitution, the floating of the fibers forming the respective reinforced layers and the adhesion of the inner layer B3 to the inner core 6c are prevented.

IPC: G02F1/133
Filed: 1990-11-14
Abstract: PURPOSE:To assure high reliability and to simultaneously improve the resolving power in the sub-scanning direction of printing picture elements by providing a period when an AC voltage pulse of the absolute above the saturation value of the element is impressed and/or a period when a voltage pulse of the absolute value below the threshold of the element is impressed in a selection period and impressing a voltage pulse group of the absolute value below the threshold of the element in a non-selection period. CONSTITUTION:A symbol 101 is the waveform of a scanning electrode, 102 is the waveform of a signal electrode, 103 is the synthesized waveform to be impressed to the element and 104 is the optical response of the liquid crystal element. The AC voltage pulse having the absolute value above the saturation value of the element is impressed in the selection period t10 in an on-selection frame t12 and the liquid crystal molecules are alternately arranged to the two stable states of a ferroelectric phase, by which the element is put into a light transmission state. Since the voltage pulse group of the absolute value below the threshold is impressed in the non-selection period t11, the liquid crystal molecules are arranged to the stable state of the diaferroelectric phase and this state is maintained. The voltage pulse of the absolute value below the threshold value of the element is impressed in the selection period t20 in the off-selection frame t22 and the element is put into a light shielding state by maintaining the arrangement of the diaferroelectric phase.

Title: Vibration damper
Inventor: KATO YOSHIKAZU
IPC: F16F15/126
Filed: 1989-11-28
Abstract: PURPOSE:To obtain a stable effect of absorbing vibration with less temperature dependency by providing a vibratory unit and a subelastic part, protruded from one side toward the other of a mass unit, in an elastic member so as to compress this subelastic part at the time of thermal expansion. CONSTITUTION:A vibration damper is constituted of a drive shaft 1 serving as a vibratory unit, cylindrical mass unit 2 arranged coaxially with a space from the drive shaft 1 and an elastic member 3 having a subelastic part 37. When an environmental temperature for use is increased, volume of the rubber- made elastic member 3 is increased by thermal expansion. Consequently, the subelastic part 37 is compressed by the drive shaft 1 and the mass unit 2 and stiffened in accordance with a thermal expansion amount. Thus by holding a spring constant of the elastic member as a whole to almost a fixed value, a stable effect of absorbing vibration with no drop of a resonance point can be obtained.
