Title: Weldable coated steel sheet of excellent adhesion to foamed urethane resin
Inventor: SAKAMOTO YOSHIKO
IPC: B05D7/14
Filed: 1997-07-08
Abstract: PROBLEM TO BE SOLVED: To provide a weldable coated steel sheet of excellent adhesion to foamed urethane resin in the coated steel sheet wherein a resin film containing a conductive agent is formed on a surface. SOLUTION: In the weldable coated steel sheet, a conductive agent is phosphorus iron powder simple substance, its phosphorus iron content is 50-70 wt.% in a film, and a coated resin contains epoxy resin and/or epoxy constituent of 0.1 to 0.6 mol per 100 g of the coated resin. In a resin film, rust preventive pigment may be added in order to raise rust preventive force. Since a conductivity of the rust preventive pigment decreases extremely when it exceeds 10 pts.wt. per 100 g of coated resin, an additional amount is preferably 10 pts.wt. or under. The rust preventive pigment to be used suffices only when it does not exert a bad influence on physical properties of the film. As an representative one, chromium series such as zinc chromate, strontium chromate, and calcium chromate are exemplified.

Title: Magnetic disk device system
Inventor: MURAI TORU
IPC: G11B19/28
Filed: 1987-08-10
Abstract: PURPOSE:To correct skewing with small capacity of data buffer by controlling the rotational period and the rotational angular phase of each of the disk rotation drive motors of plural magnetic disk devices operated concurrently so that they are synchronized with a periodical signal which is made a common reference. CONSTITUTION:The titled device is provided with a second comparator 11 that compares the phase (and frequency) of a reference index clock 5A having the same period as target disk rotational period generated by a second reference device 10 with that (and frequency) of an index clock 5 obtained from a clock discrimination circuit 4. And an output from the second comparator which is the phase difference (and the frequency difference) between said two input signals, is inputted to an adder-subtracter 12 as a correction value for an output from a first comparator 8, and the arithmetic result from the 12 is amplified by a drive amplifier 9 to drive a spindle motor 1. Accordingly, the rotational angular phase of a disk is controlled to be the state locked with the phase of the reference index 5A. As a result, the data buffer for the correction of timing skew can be reduced, and the titled system can be obtained with comparatively simple circuit.

Filed: 1986-08-27
Abstract: PURPOSE:To allow a central supervisory station to locate an open portion by allowing each repeater to independently supervise the presence of an open line fault of a CATV transmission line between the repeater and an immediate subsequent repeater and sending the result of supervision to the central supervisory station through data transmission. CONSTITUTION:A repeater 3 always sends an amplitude modulation wave generated by a pilot signal generator 13 to an outgoing transmission line 5 through a coupler 12 and a directional filter 14, fetches an amplitude modulation wave sent from a repeater 19 just preceding to a transmission line 2 similarly through a directional coupler 6, rectifies the result by a rectifier 8 via a band pass filter 7 to extract the modulation component. The modulation wave being an output of the rectifier 8 is always sent in the incoming direction of the transmission line 2 via a coupler 9 and the directional coupler 6. If an open line takes place in the CATV transmission line 5, since the repeater 3 does not detect the modulation wave outputted the incoming direction of the line 5, a data processing section 18 locates the open line 5 and the result is transferred to the central supervisory station 1 through the information data transmission.

Abstract: PURPOSE:To detect an abrasion of a bottle securely by arranging a light source and a photodetector on both sides of a passage for bottles, and detecting light transmitted through a bottle. CONSTITUTION:A light source 4 and a photodetector 5 are arranged on both sides of a passage for bottle 1 while facing each other in the direction perpendicular to the passing direction F of bottles 1; and the bottle 1 is irradiated with light form the light source 4 at height corresponding to an supposed abrasion generation position of the bottle 1 and light transmitted through the bottle 1 is guided to the photodetector 5. The light from the light source 4 is scattered according to the degree of an abrasion 1A at the abrasion at an entrance to the bottle 1, and this attenuated transmitted light is further scattered and attenuated at an abrasion 1B at an exit from the bottle 1 before reaching the photodetector 5. Consequently, the degree of an abrasion is detected more precisely than a system which detects reflected light from an abrasion even when the positioning precision of the bottle is not so high.

Title: Speed limiter for car
Inventor: YUGAWA HIDEKI
IPC: B60K31/04
Filed: 1983-10-26
Abstract: PURPOSE:To restrain the fluctuation of the speed limit due to changing a speed regulator position and to stabilize a car speed by changing the time constant of a discharge circuit, which sets the speed limits, in response to the changed position of the speed regulator. CONSTITUTION:The discharge time constants of a condenser 31 for each change position of a speed regulator are set to meet the following requirements: Regardless of the changed position of a speed regulator, when the running speed of a car is less than the speed limit, the terminal voltage of the condenser 31 goes down to such a level as to make a field effect transistor 30 conductive by the time when the output voltage (hereafter referred to as positive output voltage) of a generating coil 1 during a half cycle in the direction of the arrow shown in the figure rises. When the running speed of a car exceeds the speed limit, the condenser 31 will not discharge in time, and its terminal voltage is maintained high enough to keep the field effect transistor 30 cutoff when the positive output voltage of the generating coil 1 rises.

Title: Production of metallurgical coke
Inventor: MIURA KIYOSHI
IPC: C10B57/00
Filed: 1988-08-09
Abstract: PURPOSE:To obtain metallurgical coke of improved cold strength and hot reactivity in an economically advantageous manner by allowing carbon formed by the thermal cracking of a hydrocarbon to adhere to and penetrate into the coke at the upper part of a coking chamber. CONSTITUTION:A gaseous or liquid hydrocarbon is blown into the upper space of the coking chamber in the course of carbonization in a chamber coke oven, and the carbon formed by the thermal cracking of this hydrocarbon is allowed to adhere to and penetrate into the coke at the upper part of the chamber to obtain the purpose coke. The blowing of the gaseous or liquid hydrocarbon into the space is preferably carried out by blowing it onto red-hot coke uniformly by spraying or the like from a plurality of sites of the top of the oven such as feed holes. This is because the coke on the upper part of the carbonization chamber is more porous and has poor qualities such as strength and reactivity with CO2 because of its low carbonization temperature and low density of packing and therefore it can be given a more marked quality improving effect ascribable to the adhesion of residual coked product and the thermally cracked carbon.
