Title: Production of cam shaft
Inventor: TSUZUKI YOSHIHIKO
IPC: B21D53/86
Filed: 1984-06-06
Abstract: PURPOSE:To reduce the cost of a product by splining cup-shaped members worked from a blanked billet and sintering sinterable alloy powder to a base body joined symmetrically with a pair of such members to form a cam part. CONSTITUTION:The billet is deep-drawn and is made into the cup-shaped member 2 and detaining parts 3 having the spline pattern are formed thereto. A pair of such mated members 2 are set symmetrical to the center line and are then partially welded to obtain the base body 4 having a cam profile. The sinterable powder alloy is packed into the space between a cylindrical body 5 of a tool and the body 4 and is pressurized by a plunger puch to form a powder molding 6a which is then sintered. The completed cam part is press-fitted into a separately worked cam shaft part 10 and is fixed by a pin 12. The cam body is then welded, set and unitized by a weld zone 14 to the shaft body 10. Assembling errors are decreased by the above-mentioned method, by which the man-hour for manufacture is considerably reduced and the cost is reduced.

IPC: G07D7/00
Filed: 1988-05-13
Abstract: PURPOSE:To confirm the transport state of the whole device by installing a judging part which detects the transport interval of paper sheets from the output of a detector and judges the normality of the transport state. CONSTITUTION:A transport device confirming jig is constituted of a detecting part 10 having a pair of detectors 1 and a detected signal amplifier 2 and a judging part 20 having a detected signal absorber 3, standard value effective/ ineffective selecting switch 4, comparator 5, display part 6, and a standard value setting rotary switch 7. When paper sheets 8 and 9 are transported, the detector 1 detects the front edge of the paper 8, and then detects the front edge of the paper 9. The detection signal absorber 3 distance-conversion- calculates the detected interval of the detector 1, and when comparison with the standard value is performed, the measured value is transported to the comparator 5, while if comparison is not carried out, the measured value is transported to the display device 6 for the display at all times. When the measured value is transported to the comparator 5 for the comparison with the standard value, display is performed only in the case when a standard value range is exceeded, and the anomaly of the transport device is confirmed.

Abstract: PURPOSE: To make possible controlling of traffic signal lights and judgement of untrafficable roads by providing a microprocessor and providing a multiplicity of vehicle detectors capable of always knowing the time until the reflected waves from road surface are received.  
     CONSTITUTION: The t' 4  of the ultrasonic waves transmitted at t' 0  varies within the predetermined range of ±α. Vehicle judgement threshold value is assumed to be β. Now, the time when the reflected waves from road surface are received, e.g., t' 4 , is stored in a specified area and the difference (a) between the time of the reflected waves of this time and t' 4  are computed by a microprocessor. If this difference (a) is less than α, the reflected waves are judged to be the reflected waves from the road surface and the previously stored data t' 4  is renewed. If (a) is larger than β, the waves are judged to be the reflected waves from a vehicle, and a vehicle detection signal is outputted. Such vehicle detectors are provided in multiple points and a central control room collects the data therefrom and controls traffic signal lights with a computer, or it is possible to judge untrafficable roads out of roads

Title: Dry etching method
Inventor: TATSUMI TETSUYA
IPC: H01L21/302
Filed: 1991-04-22
Abstract: PURPOSE:To improve base selectivity at the time of overetching in the case of dry etching a silicon-based material layer without using fluorocarbon based gas. CONSTITUTION:For example, in the case of forming a gate electrode of a MOS- FET, S2F2, S2Cl2, etc., is used to (just) etch a polycrystalline silicon layer in thickness corresponding to that of the layer, and a gate electrode having an anisotropic shape is formed at a high speed by contribution of F*, Cl*, etc., and sidewall protecting operation of S(sulfur). Thereafter, in order to remove the residual polycrystalline silicon layer, bromine-based gas such as HBr, S2Br2, etc., is used to overetch it. As apparent from the fact that magnitude relationship of interatomic bonding energy is Si-O>Si-Br, the Br* does not spontaneously etch SiO2, and hence high selection ratio to a ate oxide film is performed.

Title: Data copy system between rotary type memory units
Inventor: KONAKA SEIJI
IPC: G11B20/10
Filed: 1977-09-30
Abstract: PURPOSE: To complete the data copy in a short time, by using a small capacity of buffer memory.  
     CONSTITUTION: The buffer memory 26 for one setter's share is provided at least, and when the information copy is made from the disc D1 to D2, only if the diffference of revolution of D1 and D2 is amaller than 1/2 revolution (most suited revolution difference), two tracks are required. But, in case of disc, since the track like this is given as a spare, no problem is taken place. This is artificially inserted between the memory 26 and the rotary unit and data copy is made. Further, the relation between the copy processing time in this case and the phase difference of revolution is as shown in the curve l 1  (solid lines), and when the number of sectors per one track is taken as n, the minimum copy processing time is 2+1/n revolution (perfect synchronism) and if the rotary phase difference is less, it can be useful. (The curve l 2  shows the case that D2 is delayed from D1 by 1/2 revolution)
