Title: Testing apparatus for magnetic disc
Inventor: HINOBAYASHI TAKEO
IPC: G01N3/56
Filed: 1989-09-12
Abstract: PURPOSE:To evaluate abrasion resistance efficiently by providing a means for imparting upward warping between a rotary table and a magnetic disc, and bringing a head slide in a levitating state into contact with the surface of the warped disc or hitting the surface. CONSTITUTION:A deforming ring plate 2 is arranged at the outer peripheral part of a rotary table 1. A magnetic disc is arranged on the ring plate. The inner part of the disc is fixed with a flange metal fitting 3. The disc 4 is inclined in the outward direction, and warping is imparted in a bowl state. A head slider 5 is arranged on the surface of the magnetic disc 4. The disc 4 is rotated, and an edge part 5a of the slider 5 is brought into contact with the disc. The operating attitude of the slider 5 becomes unstable, and the hitting frequency is increased. The abrasion resistance of the disc 4 can be tested and evaluated in a short time based on the number of repeating times of the rotation operation until the disc is damaged.

Title: Electric iron
Inventor: KATAOKA YOSHINORI
IPC: D06F75/26
Filed: 1988-09-22
Abstract: PURPOSE:To eliminate the over-heat of a base even when abnormality is generated in reference resistance and to establish the safety of an iron by composing a reference resisting part, which is inputted to a comparator, of one fixed resistor and the plural resistors of different values, which are parallelly connected to the fixed resistor selectively by a changeover switch, or a variable resistor. CONSTITUTION:At first, one of resistors 5a-5c is selected by a changeover switch 6 and the temperature of the base is set. When a heater 11 is heated, the base temperature rises up and for a thermister 1, the resistor is changed according to a characteristic. When the temperature of the base goes to be the set temperature, a voltage divided by the thermister 1 and a resistor 2 is coincident with a reference voltage which is formed in a reference resisting part 3. A comparator 8 compares the divided voltage in the thermister 1 and the reference voltage and a signal is outputted to a heater control circuit 9 so that electrification can not be executed. Then, the electrification to the heater 11 is turned off. When a turning-off condition continues and the resistance value of the thermister 1 is changed, the comparator 8 sends a signal again to turn on the electrification to the heater 11 and the electrification is turned on by a heater control circuit 10. By repeating this operation, the electrification to the heater 11 is turned-on and off and the constant temperature is kept for the base.

Abstract: PROBLEM TO BE SOLVED: To remove reduction in the accuracy of time synchronization due to jitters in a distributed system by expressing the relative synchronization of local clocks on 1st and 2nd nodes by a difference of time stamps between a local time value and a follow-up packet. SOLUTION: A time value stored in a time stamp lach 38 indicates local time when a time packet recognition mechanism 32 receives a timing data packet 18. Then the mechanism 32 receives a follow-up packet 16 and extracts a time stamp 50. The relative synchronization of local clocks 22, 36 on nodes 12, 14 is expressed by a difference between the time stamp 50 and the time value of the latch 38. Once calculating the difference, the mechanism 32 adjusts the time value by using the difference in order to allow the local clock 36 to coincide with the local clock 22.
