Abstract: PURPOSE:To attain the stable response of a servo device against a high speed rotation by providing a circuit having a transmission characteristic in which a peak value varies following the change of the eccentric fundamental frequency of a rotary recording medium within a servo system loop. CONSTITUTION:By switching a switch S1 replying to the rotating number of an optical disc and the value of a resistor R1, a resonance point is changed following the eccentric fundamental wave component of the optical disc, and the maximum loop gain against the eccentric fundamental wave frequency can be given.

Therefore, resistors r9, r7, and r8 are adjusted relating with the mechanical response characteristic of an actuator, and factors a2, a1, and a0 are set. The switches S2 and S3 of a transmission element GC3 which constitutes a phase-lead circuit are switched similarly as the switch S1 replying to the rotating number of the optical disc, and the neighborhood of a phase at omegad is stabilized.

Title: Japanese sentence reading-aloud device
Inventor: TERAMOTO YOSHIAKI
IPC: G06F17/21
Filed: 1988-10-04
Abstract: PURPOSE:To prevent the erroneous identification of a word caused by punctuating a character string at an improper punctuating point by performing sentence analysis when a specified symbol designated previously is detected in an input character string by recognizing the detected specified symbol as a morpheme analyzing boundary. CONSTITUTION:A user inerts previously a punctuation symbol capable of designating distinctly a morpheme boundary. As for an input sentence 1, the punctuation symbol existing in the input sentence is extracted by a punctuation symbol extracting part 2, and position information related to the extracted punctuation symbol 5 is sent to a sentence analyzing part 3. In the sentence analyzing part 3, the word extending over the morpheme punctuation symbol is deleted from a word candidate, or the word extending over the morpheme punctuation symbol is processed so as not to be retrieved at the time of the retrieval of a dictionary. Thus, a flat written Japanese sentence in which KANJI (Chinese character) and KANA (Japanese syllabary) are mixed is prevented from being punctuated at a place not intended by an inputting person or an unnatural place and turning into an unnatural sentence.

Title: Diaphragm device for endoscope
Inventor: YASHIMA HIROYUKI
IPC: G02B26/02
Filed: 1984-11-26
Abstract: PURPOSE:To obtain a diaphragm device for an endoscope which has simple and compact constitution, makes diaphragm adjustment accurately, and reacts excellently by providing a diaphragm which has a diaphragm blade made of a bimorph element in the middle of an objective optical system. CONSTITUTION:When an observation in the body cavity is made, illumination light is projected from an illumination window 3 to light the inside. When a position to be observed is close, a light image incident from the observation window 2 becomes bright and is hard to focus. When the position to be observed is distant, on the other hand, the light image becomes dark and is easily put in focus. For the purpose, a signal processing circuit 9 which processes an image signal obtained by a solid-state image pickup element 6 detects the brightness of the image. A driving voltage circuit 15 receives its detection signal to generate a control voltage, which is applied to the diaphragm blade of the diaphragm 11 provided in the middle of the objective optical system 5. For example, when the position to be observed is distant, a large voltage is applied to deform the diaphragm blade 12 as shown by a dotted line, thereby increasing the degree of opening of the diaphragm 11. Consequently, a visual field image to be observed increases in brightness and an excellent observation is made.

Title: Formation of bump and manufacture of semiconductor device using it
Inventor: FUTAMI MASAHITO
IPC: H01L21/60
Filed: 1997-08-28
Abstract: PROBLEM TO BE SOLVED: To prevent the height fluctuations among bumps. SOLUTION: A wire 21 is passed through the capillary 31 of a wire-bonding device until the front end of the wire 21 is protruded from the capillary 31 by a preset length H, and a ball 23 is formed by melting the protruded end section 22 of the wire 21 through heating with a discharge torch 32. The ball 23 which ascends, while increasing in size stops at the front end face 31a of the capillary 31 and forms a constricted section 24 at the junction between the wire 21 and ball 23. The ball 23 is press-contacted with the front end face 31a of the capillary 31 by means of an electrode pad 13. The capillary 31 is raised, and the wire 21 is drawn out from the capillary 31. The capillary 21 is raised, while a clamper clamping the wire 21 and the wire 21, is torn off at the constricted section 24.  Therefore, a circuit, etc., formed below each electrode pad can be prevented from being damaged, because a group of bumps is formed with uniformed heights at the time of performing gang bonding.
