Title: Photosensitive body unit for copying machine
Inventor: ANDO TOSHIAKI
IPC: G03G15/02
Filed: 1985-05-08
Abstract: PURPOSE:To obtain a stable copy image by providing an impedance element or circuit between the shield member of an electrostatic charging corotron and the ground member of a photosensitive body and determining the electrostatic charging output current of a high voltage power source according to the impedance value. CONSTITUTION:The photosensitive body unit 1 of a copying machine has a resistor 7 interposed between a corotron wire 4 and a photosensitive body ground member 6 in the unit 1 to control the electrostatic charging current. For example, a photosensitive body unit B obtains Z0 as resistance Z, ISO as a current IS, and VDDP as the electrostatic charging potential on the surface of the photosensitive body. The high voltage power source 8 can have the voltage controlled to set a curve of the current ISO to the resistance value Z0 as shown on the right side in a graph. When a photosensitive body unit B is mounted on the power source having the characteristics like this, the characteristic curve of the current IS and potential VDDP is different from that of the photosensitive body unit B, so a specific charging potential VDDPO is obtained as long as the resistance value Z of the resistor 7 is set to ZA. Thus, the photosensitive body unit is only replaced to hold the surface charging potential of the photosensitive body unit nearly constant, obtaining stable images.

Title: Speed changing equipment of tilt-cab-type automobile
Inventor: AKEZORA NOBUO
IPC: F16H61/26
Filed: 1983-05-31
Abstract: PURPOSE:To simplify the design of the speed changing equipment of a tilt-cab- type automobile and prevent the gear from disengagement by breaking the linkage relation between a change lever and an engine when the automobile performs tilting operation. CONSTITUTION:A change lever 4 disposed on the floor 5 of a cab is supported by a supporting member 6 and is at the lower end thereof pivotally supported via a pin 18 by a supporting link 17 which is inserted in a control rod 3 connected to an engine-side speed change gear 2. A connecting rod 15 having a fork end 16 which is to be engaged with the pin 14 on the control rod 3 is supported by the lower end of the change lever 4 and locked by a stopper 21 so as not to turn downward when the cab makes tilting operation. For usual speed- change operation, the movement of the change lever 4 is transmitted to the speed change gear 2 via the pin 14. However, for tilting operation, the fork end 16 is uncoupled from the pin 14, therefore allowing the supporting link 17 to stretch from the control rod 3.

Title: Manufacture of semiconductor device
Inventor: SAKAGAMI AKIRA
IPC: G03F7/095
Filed: 1982-06-04
Abstract: PURPOSE:To prevent the resist pattern from becoming thinner than a desired width by the light reflection at the step of an Al layer by coating a resist of refraction coefficient n1 and a resist of refraction coefficient n2 on the Al layer when etching it. CONSTITUTION:After evaporation of an Al layer 13, a first resist 141 with refraction coefficient n1 is coated on it, and then a second resist 142 with refraction coefficient n2 is coated on the first resist 141. Both coefficients have the relationship of n1>n2. Since a light that passes through a mask 15 is totally reflected at between the resist 141 and resist 142, the light after the reflection is as shown by Fig. B, and the tightness of the contact of the resists with the Al face is increased, eliminating gaps among them. Thereby the cut in the Al layer and Al wirings due to steps can be prevented.

Abstract: PURPOSE: To enable a simple constitution to make drift corrections on each measurement without reducing a processing rate by providing a method of measuring the photo absorptivity of distilled water led into a flow cell for the washing of the flow cell.  
     CONSTITUTION: After photo absorptivity is mesaured in the 1st half measurement cycle, position control circuit 18 is driven by a control circuit in the calibration cycle. Position control circuit 18 extracts suction pipe 12 from reaction pipe 1 and then inserts it into distilled water supply part 19. Simultaneously, suction pump 14 rejects a sample in flow cell 13 from point C and also leads the distilled water to flow cell 13. In this state, flow cell 13 is irradiated with light source 15 and the quantity of light passing through flow cell 13 is detected by photo detector 16. The output of photo detector 16 at this time is used as a reference signal and an output signal obtained in the measurement cycle is corrected by using the reference signal, so that high-precision measurement can be carried out.

Filed: 1983-05-31
Abstract: PURPOSE:To improve the propriety for extraction of candidate words as well as the fixing speed of these words by taking the position of each word in a sentence into consideration when the candidate words for converted are extracted. CONSTITUTION:A maximum likelihood candidate word extracting part 22 consults a dictionary at and after the head of an input sentence to extract words, recognizes the appearing probability of words and sends the words with their appearing probability to a word store buffer. Then the words are taken out of the word buffer one by one to perform the integrated evaluation for appearing probability. Thus a word having the highest evaluation for appearing probability is delivered. An interpreting part 24 for parts of speech interprets the parts of speech with each word obtained through the part 22. Then the number of words which are decided as autonomous words is counted by an autonomous word counter 25. When the count contents of the counter 25 exceed the prescribed threshold value, a fixing processing part 26 is actuated to fix the first one clause of an unfixed candidate word train having a maximum likelihood.
