Title: Slip testing method of digital switchboard
Inventor: SOGA SENJI
IPC: H04M3/24
Filed: 1981-08-24
Abstract: PURPOSE:To easily execute a test of a slip function of a transmission line interface of a switchboard, by providing a signal delaying device which is capable of continuously varying the extent of delay, on the transmission line interface, and artificially generating a slip generating condition. CONSTITUTION:A variable delaying circuit 307 varies a delay time of a signal by a voltage value outputted from a delay controlling circuit 308. For instance, when reference clock frequencies of both A station side and B station side are equal, in case of delaying a transmission clock, as output voltage of the delay controlling circuit 308 is varied so that delay is gradually increased, a B station switchboard clock catches up with a transmission line side clock, and a slip is generated. Also, in case of quickening the transmission line side clock, as the output voltage of the delay controlling circuit 308 is varied so that delay is gradually decreased, the transmission line side clock catches up with the switchboard side clock, and a slip is generated in the same way.

Filed: 1981-08-24
Abstract: PURPOSE:To achieve economical high speed driving of a ram by forcingly circulate a fluid in one chamber of a cylinder which is ordinarily wasted as useless when no or minor load is applied on the ram, into the other chamber for application as a driving source. CONSTITUTION:For operation of a hydraulic jack or the like, when, with a manual valve 32 closing a flow passage 30, fluid pressurized by a pump is first constantly supplied for a fluid supply port 25 at a fixed rate, the fluid runs into a chamber 18 from an inflow port 28 to force a piston 16 left. The fluid then forcibly open a valve 21 and circulates into the chamber 18 because a valve 34 is kept closed. The chamber 18 is supplied with both fluids from the chamber 19 and the pump so that a ram 15 is driven at high speeds. When a working block 22 at the extremity of the ram 15 comes into contact with a work substance, the pressures in both the chambers 18 and 19 are increased high enough to actuate a pilot piston 38, whereby the valve 34 is opened via a working rod 40 to discharge the fluid in the chamber 19 through a duct 46. A valve 21 is then closed.

Title: Plasma processing and plasma processor
Inventor: KAJI TETSUNORI
IPC: H01L21/3065
Filed: 1989-05-29
Abstract: PURPOSE:To accelerate the processing rate by a method wherein a processing gas is turned into plasma by pulse discharge so as to process a specimen using the plasma. CONSTITUTION:The etching term is divided into e.g. two sections so that the etching process at high electron temperature may be performed using pulse discharge during the former section (scores of seconds) while the normal little damage etching process may be performed during the latter section (several seconds-a score of seconds). That is, when an intensive discharge is started in a feeble or no discharge state, a high energy is given to the discharge at the starting point to raise the electron temperature of the discharge. When the discharge is restored to the feeble or no discharge state after the lapse of specific time, the electrons, charged grains etc., generated by the intensive discharge are attenuated by the recoupling, etc., at the walls of a vessel. Accordingly, when the intensive discharge is started again, the high energy is given to start the discharge resultantly raising the electron temperature of discharge. Through these procedures, the etching process at high rate doing little damage can be performed.

Title: Recognizing system for on-line handwritten character
Inventor: KIMURA YOSHIMASA
IPC: G06K9/46
Filed: 1985-06-20
Abstract: PURPOSE:To attain recognition of hand-written characters written in the running hand by using a virtual stroke for extraction of the points opposite to each other between an input character pattern and a standard pattern and therefore calculating correctly the distance between both patterns. CONSTITUTION:The virtual stroke going to a pen-down point from a pen-up point is extracted for both an input character pattern and a standard pattern stored previously respectively. Then a distance matrix is produced based on the distance between both virtual strokes, and the minimum (maximum) matrix element is detected with all columns (rows) of the distance matrix. The minimum matrix elements of all rows are added together and the total value of the distance between both virtual strokes is obtained. While a section of correspondence is prescribed by the correspondence points adjacent to each other for each pattern among all correspondence points. Then the distance between the corresponding section strokes is calculated between both patterns. The inter-stroke distances are added together among all corresponding sections and therefore the distance between both patterns is obtained. Thus the input character patterns are sorted and recognized by means of both distances (degree of resemblance).

Abstract: PURPOSE:To provide a subject device excellent in snow melting property and obtaining clear images without the thermal distortion of a reflection mirror by providing plural reflection mirror rear faces, heater unit and heat insulator and sticking the plural heater units electrically connected on the plural reflection mirror rear faces by a crossover track. CONSTITUTION:An equal heat sheet equally distributes heat from a cord heater 7 to the part of a rib member 2, equally distributed the temperature of reflection mirror rear faces 3 and prevents the thermal distortion from occurring at a reflector 1. Heater units 4 are closely stuck on the reflection mirror rear faces 3 and further surrounded with a back shell 13 mounted in a space surrounded by the rib member 2 so as to be covered with a heat insulator 12 and therefore, most of generated heat is transmitted to the side of the reflection mirror rear faces 3. Thus, the rear faces 3 of the reflector 1 can be heated at the equal temperature with a little energy consumption, and quick heating property is improved. Further, since the rib member 2 is serially connected to the reflection mirror rear faces 3 in crossover by a crossover trunk 9 or the cord heater 7 as plural units, the number of lead wires to be connected to reduced and workability is improved. As a result, the snow melting property is improved, the thermal distortion of the reflection mirror is prevented, and sharp image can be obtained.
