Title: Granular sulfur for vulcanization of rubber
Inventor: YOSHIDA NOBORU
IPC: C01B17/00
Filed: 1985-09-02
Abstract: PURPOSE:To improve the dispersibility and fluidity of sulfur and suppress the dusting tendency and the blocking of sulfur during storage, by adding a specific amount of ethylene glycol to powdery sulfur and mixing and granulating the mixture. CONSTITUTION:Powdery sulfur is mixed with 0.1-50wt% one or more compounds selected from ethylene glycol, diethylene glycol and triethylene glycol. The particle size of the powdery sulfur is preferably finer than about 150 mesh. The mixture is granulated to obtain granular sulfur for the vulcanization of rubber.

Title: Drive method for ink jet recording head
Inventor: MATSUMOTO HIROZO
IPC: B41J2/045
Filed: 1989-07-25
Abstract: PURPOSE:To eliminate a satellite to improve a printing quality and stabilize an ink discharge by a method wherein a rising time of a drive voltage pulse is made equal to a natural vibration period of an ink volume speed in an ink nozzle, and a falling time of the voltage pulse is made n-times longer than the natural vibration period. CONSTITUTION:A rising time of a voltage pulse is made equal to a natural vibration period of an ink volume speed in an ink nozzle, and a falling time of the voltage pulse is made n-times longer than the natural vibration period, where (n) is a natural number. Thus, an ink discharge action is conducted approximately once per pulse, which inhibits an excess vibration to substantially prevent the occurrence of a satellite. When a falling time is tA = 2T (T is a natural vibration period of an ink volume speed in an ink nozzle), a ratio B/A is approximately 6.6%, where B is a maximum value of a satellite and A is a maximum value of a main ink drip. If the shape of an piezoelectric element is changed, the occurrence of satellite can be eliminated to realize a stable ink discharge by controlling the falling time tA and a rising time tB in a voltage pulse wavefrom according to the natural vibration period T.

Title: Detecting structure for slack of belt
Inventor: YAMASHITA HIROSHI
IPC: G01L5/04
Filed: 1990-07-23
Abstract: PURPOSE:To check up the slackening state of a belt visually and thereby to enable early prevention of the occurrence of the slack of the belt by a method wherein a variable-color member of which the color is changed by temperature is attached to a visible place of the belt driven by a frictional force. CONSTITUTION:A variable-color member of which the color is changed by the temperature of a belt rising with the occurence of the slack of the belt is attached to a visible place of the belt driven by a frictional force, and the slack of the belt is detected therefrom. As for the variable-color member, a colored paint or the like can be mentioned. The color of the colored paint, which is changed differently in several stages by temperature, is formed of macromolecular materials and can be prepared so that its color can be changed at a certain prescribed temperature, by varying the composition of the materials. Since there is a large difference in the temperature of the belt between the case when the belt is in an ordinary slipping state and the case when a 4% or more slip occurs, it is possible to prepare and form the colored paint so that the color of the belt can be changed at the heating temperature whereat this slip occurs.

Title: Focal length variable liquid crystal lens
Inventor: HIBINO KOETSU
IPC: G02B3/00
Filed: 1991-08-01
Abstract: PURPOSE:To provide the focal length variable liquid crystal lens which does not require polarizing plates and is simple in construction. CONSTITUTION:A liquid crystal 8 having positive dielectric anisotropy is sealed between a pair of transparent substrates 1 and 4 to form a liquid crystal cell. The liquid crystal 8 turns to a cholesteric phase having the spiral structure of planar molecular arrangement at the time of non-impression of an electric field and turns to a nematic phase of homeotropin molecular arrangement when the liquid crystal is impressed with the electric field. The liquid crystal cell is a PC type liquid crystal cell. The liquid crystal molecules are twisted and arranged by 360 deg. in the major axis direction thereof and the polarization components in all the directions of incident light with the liquid crystal molecules arranged in such a manner turn to extraordinary rays at the time of the non-impression of the electric field. The liquid crystal molecules gradually change the major axis direction thereof in the electric field direction when the liquid crystal is impressed with the electric field and, therefore, the apparent refractive index of the liquid crystal 8 changes continuously from the value to extraordinary light to the value to ordinary light for the polarization components of all the directions. The effect of varying the focal length is thus attained.

Title: Optical wavelength multiplexed repeater
Inventor: TAKACHIO NOBORU
IPC: H04B10/07
Filed: 1998-07-08
Abstract: PROBLEM TO BE SOLVED: To detect the failure or deterioration of an optical linear amplifier by identifying the optical signal level of maximum power in plural light wavelengths that are outputted from the optical linear amplifier and are subjected to light wavelength multiplexing. SOLUTION: A part of an output of an optical linear amplifier 1 is branched by an optical demultiplexer 12 and a wavelength multiplexed signal is demultiplexed by using an optical demultiplexer 8 in every wavelength. Next, an optical signal is converted into an electric signal by using a photoelectric converter 9. A P-I-N photodiode output is connected to a diode circuit 10 consisting of plural diodes having the same forward charateristic. Because the P-I-N photodiode output outputs DC current which is in proportion to light power that is made incident, in the circuit 10, only diodes corresponding the maximum power channel are turned on and maximum channel power in an output of the amplifier 1 can be detected. When the maximum channel power is out of a required range, it is decided as a failure.

Title: Burst signal detecting control circuit
Inventor: SHIYOUMURA TATSUROU
IPC: H04L27/22
Filed: 1983-10-17
Abstract: PURPOSE:To attain initial acquisition at a low C/N state and to reduce a pre- word of a burst signal by narrowing a band of a band limit filter and setting a generation time of a control signal to the end time in the process of synchronism locking for carrier regeneration of the next burst signal. CONSTITUTION:The effect of noise on an input burst signal (Fig. a) to a band limit filter 22 is decreased by narrowing the band and an output of a burst signal detection circuit is Td' which is delayed further than a conventional delay time Td. On the other hand, the generation time of a control signal 19 adjusts a preset value of a preset counter 27 and gives a delay by Tf-Td+Tc time. As a result, the control signal 19 is generated at a position delayed by the time Tc from a head time of the next burst signal and a pre-word of carrier regeneration is reduced to the Tc. Since the effect of noise is decreased as mentioned above and the frame period Tf frequency stability is high in a time division multiple address (TDMA) system, the generation time of the control signal 19 is stabilized and the initial acquisition at a low C/N state is attained.
