Title: Production of watchcase
Inventor: MUTOO NORIYOSHI
IPC: B29C35/00
Filed: 1980-06-26
Abstract: PURPOSE: To easily produce an injection-molded article having a metallic film formed thereon, by preliminarily providing a metallic film on the inside surface of a mold by electrocasting.  
     CONSTITUTION: The metallic films 5, 6 are formed on the inside surfaces of insert pieces 3, 4 of the mold by electroforming or the like, and a molten resin at a high temperature and a high pressure is injected into the mold cavity via a gate 1a to produce the watchcase having having the metallic film thereon. Since there is no  need to preliminarily press-working a metallic plate intended for covering an article  or to place it in a mold, the production process is easy and there is no fear of generating flaws or other troubles due to the inconformity between the inside surface  shape of the mold and the outside shape of the metallic plate. In addition, in the  case of a quartz oscillation type watch, the inside surface of the watchcase is coated  with a conductive metal 5 by vacuum deposition since the watchcase is utilized as a  part of a conductive circuit.

Title: Speech processing and synthesization method and apparatus
Inventor: DEBITSUTO ERU TOMUSON
IPC: G10L19/02
Filed: 1989-04-07
Abstract: PURPOSE: To enable the formation of high-quality synthesized speech by determining spectra from speech, calculating a parameter set for setting plural sinusoids in accordance therewith and sending this parameter set as the sum of the sinusoids to a speech synthesizer. CONSTITUTION: An A/D converter 110 converts the analog speech signal inputted thereto to digital speed samples which are processed by a speech analyzer 120. A series of the parameters obtd. by this analyzer 120 are sent to a channel encoder 130 and are encoded, following which a channel decoder 150 receives a quantization parameter via a channel 140 and decodes the same. The decoded parameter is sent to the speech synthesizer 160. The synthesizer 160 processes the parameters and forms the digitally synthesized speech. A D/A converter 170 processes this digitally synthesized speech and reproduces the analog speech signals.

Title: Thin film transistor and manufacture thereof
Inventor: RAMESHU KAKAADO
IPC: H01L29/786
Filed: 1999-03-30
Abstract: PROBLEM TO BE SOLVED: To provide the manufacturing method of polycrystalline or microstalline TFTs with an increased on/off current ratio and an increased mobility. SOLUTION: This manufacturing method of polycrystalline or microstalline TFTs is achieved by doping a certain part of a channel n-type and a certain part of a channel p-type, whereby a p-n junction is formed within a channel. In such a structure, when a gate voltage is applied, an off-current is reduced by the p-n junction within the channel. When a positive (or negative) bias is applied, a p-type (or an n-type) region of the channel is inverted, and a high channel conductance can be obtained by the n-type (or p-type) region of the channel. Hereby, while the off current is kept low, the on-current and mobility of the TFTs are increased.

Title: Washing method of tubular membrane separation apparatus
Inventor: TAMARU SHIYUUSAKU
IPC: B01D61/18
Filed: 1983-05-17
Abstract: PURPOSE:To wash efficiently a membrane with a low additional cost by eddying the current of an original liquid at the original liquid inflow port to distribute uniformly washing balls to the membrane separation tubes which are arranged in parallel. CONSTITUTION:A cover 3 is installed to a tubular separation tube 1 through a holder 2 and a ring 31. An end cap 41a for the inflow of an original liquid. Which is jointed with a bolt 51, is equipped tangentially to the circumferential direction of the cap so that the influent liquid can be eddied. In addition, the cross-sectional area of the flow passage is reduced as it nears the eddy direction. However, since the flow rate of the influent liquid is branched as the liquid proceeds to the center, the area of the flow passage is decreased in correspondence with the decrease of the flow. In this way, the flow rate of the eddy current can be made uniform over the full length of the passage. Accordingly, the settling and omnipresence of the balls in the end cap can be prevented sufficiently, and the balls can be distributed uniformly.

Thus, the angle of rotation of an eccentric ring 12 is finely controlled. Further, if necessary, a bolt and a nut 22b of a fixture 22 are loosened to turn a strip 22a with respect to a support rod 21 and fix the same. In order to coarsely control the angle of rotation of the eccentric ring 12, a pin 24 is pulled out from a rotation angle control hole 12c of the eccentric ring 12, the fixture 22 is loosened and turned, and the eccentric ring 12 is turned. The pin 24 is again inserted in an obtained rotation angle control hole 12c.
