Title: Measurement of effective value
Inventor: IGAWA HIROSHI
IPC: G01R19/02
Filed: 1982-03-29
Abstract: PURPOSE:To enable accurate measurement of effective values with limited errors in the computation accompanied by frequency variations in the waveform of the AC input by correcting a sampling value of the AC input waveform with a deviation between the actual frequency and the reference frequency. CONSTITUTION:An AC input waveform obtained through a potential transformer 1 undergoes an A/D conversion detecting two sampling values having a fixed phase difference pi/2 in the reference frequency f0 with an A/D converter 2. A frequency transducer 3, outputs a level signal proportional to the frequency f0 of the AC input waveform to be fed the A/D converter 2. The A/D conversion outputs thus obtained is sent to an effective value arithmetic unit 4 and one of sampling data is corrected by a phase pi DELTAf0/2f0 according to a variation value DELTAf0 of an actual frequency f0' from the reference frequency f0 to form a data with a relative phase difference separated just by pi/2 whereby an effective value is calculated. This enables the correction of errors in the computation of a digital effective value accompanied by variations in the AC input frequency.

Title: Axle locking means in industrial vehicle
Inventor: KOJIMA TAKEO
IPC: B60G17/005
Filed: 1982-03-27
Abstract: PURPOSE:To obtain an axle locking device whose structure is simplified by providing a pipe passage with a pair of check valves which are intended for cutting off communication of cylinder chambers thereto. CONSTITUTION:When a locking motion signal S4 is outputted from a discrimination circuit H to excite a solenoid 36, a solenoid valve 35 is changed over to a cut-off port 35b from a communication port 35a. Cylinder chambers R1 and R2 of lock cylinders 30 are then cut off so that piston rods 32 are fixed to a frame 1a to lock a rear axle 3. Since the cylinders 30 are designed in a single operation unit and are fixed to the lower face of the frame 1a and the bottoms of the rods 32 are arranged to abut the upper face of the rear axle 3, the number of parts may be reduced and the structure can be simplified. The check valves 38 and 39 assigned for use in the cut-off port 35b of the valve 35 may prevent oil in the port 35b from leaking under the cut-off condition, hence surely maintaining the locking condition.

Title: Plasma etching method and manufacture of semiconductor device
Inventor: HIKOSAKA YUKINOBU
IPC: C23F4/00
Filed: 1995-03-09
Abstract: PURPOSE: To improve the etch selectivity and etching rate of an oxide film against silicon by setting the discharge idling period of intermittently excited inductive coupled plasma so that ion concentration can be attenuated to a sufficiently low level and radical concentration cannot change much during the period. CONSTITUTION: In the course of plasma etching which is performed for selectively etching a silicon oxide film, a plasma annihilation period 1 is set in such a way that the mean value with respect to the time of ion concentration at the plasma generating position can become 80-20% of that at the plasma annihilation time during the period and a silicon substrate is placed on a substrate holder across which a DC bias is applied. When the period 1 is set at 40μsec, the etching rate of the oxide film increases and the etching rate of silicon decreases as compared with the case where the plasma is continuously discharged. Consequently, the etch selectivity of the oxide film against silicon becomes about four times as large as that obtained in the prior art example where the plasma is continuously discharged.  Therefore, plasma etching which is improved in both etching rate and etch selectivity can be provided for oxide films.

IPC: B21D5/02
Filed: 1983-03-25
Abstract: PURPOSE:To correct easily the spring-back which arises after bending, in the stage of bending a thin metallic plate by means of a bending punch and a bending die, by splitting the bending die and exerting the side pressure sliding in a horizontal direction thereto. CONSTITUTION:When bending of a blank material 1 by a bending punch 2 is started by lowering a punch plate 10, slide cams 9 are lowered simultaneously as well by the guide of a die holder 8. When the tapered end faces 14 of the wedges 13 of the cams 9 contact the side faces 15 of split dies 5, 5' supporting the material 1, a dide pressure is generated in the horizontal direction to close the gap 6 between the dies 5 and 5', and the material 1 is bent by the dies 5, 5' and the punch 2. The side pressure to be exerted on the dies 5, 5' during forming is changed as desired by adjusting the height of the cams 9 by means of screws 12 in this stage, by which the stress applied on the material 1 is changed and the spring-back is corrected.

IPC: G06F17/30
Filed: 1988-03-04
Abstract: PURPOSE:To easily input adjacent map data by defining a logical map control address in a map retrieve control part, defining the map as an aggregate for one section in a defined logical space, and retrieving the number of the maps adjacent to the map displayed on a display part on reference to the logical space. CONSTITUTION:In a map retrieve control part 22, the logical map control address independent of the physical map address is defined, and the map is defined as the aggregate for one section in the mesh space defined by the logical map control address. That is, in the map retrieve control part 22, the logical mesh space is prepared regardless of the map actually inputted from a scanner 24, etc., and the collected plural meshes are made to correspond to the real map. Thus, even if the longitudinal and transverse lengths of the map are different, and the scale of the adjacent map is different, by making the logical map exist on the same mesh space as an area, it can be unitarily controlled, and an adjacent map 4 can be unitarily discriminated.
