Title: Method for crystal growth
Inventor: KURODA TAKAROU
IPC: C30B23/08
Filed: 1981-06-17
Abstract: PURPOSE: To reduce the poisonous hazard, and to facilitate the control of vapor pressure in the growth of a semiconductor crystal by molecular beam epitaxial growth process, by using a compound of the semiconductor-constituting elements and an element having specific properties as the evaporation source material.  
     CONSTITUTION: A compound of one or more elements constituting the required compound semiconductor and an element having a sticking coefficient to the substrate of nearly zero, is used as the evaporation source material. It is essential to use a compound of a V-group element especially As or P, and an element having a sticking coefficient to the crystal of nearly zero, e.g. Zn or Cd. The compound is e.g. ZnAs 2 , Cd 2 P 3 , etc. which are stable at room temperature and have low toxicity. When the compound is heated at a high temperature in a crucible, etc., it decomposes into e.g. Zn molecule and As 2  molecule, and the latter molecule is bonded with Ga which is the other evaporation source, and a GaAs crystal is formed on the substrate. The Zn molecule does not bond with Ga nor recombine with As. Since the As is not liberated separately from Zn, the rate of evaporation of the evaporation source can be controlled easily by controlling the heating temperature.

Title: Printing head gap adjusting mechanism for printer
Inventor: NAGAI MIKIO
IPC: B41J25/308
Filed: 1987-04-15
Abstract: PURPOSE:To eliminate the need for a paper thickness adjusting operation carried out by the user and to contrive the prevention of time loss and of a trouble due to misadjustment, by adjusting a printing head gap according to the thickness of a recording paper detected by a linear sensor. CONSTITUTION:At an initial position where a recording paper 4 is absent, a platen 8 and a printing head 5 are spaced most apart from each other. A pinch roller 23 and a paper-supporting roller 25 are in contact with each other, so that a linear sensor 21 stores this position into a controlling part as the initial position. When the paper 4 is present, a scale shaft 22 is moved in the direction of an arrow D, so that the sensor 21 outputs the moving quantity to the controlling part as a movement signal. Upon receiving the movement signal, the controlling part decodes the signal, and outputs a predetermined pulse corresponding to the thickness of the paper to a pulse motor 34. The pulse sent from the controlling part actuates the motor 34 to rotate a guide shaft 3 in the direction of an arrow G, whereby the head 5 is moved to the side of the paper 4, and is enabled to perform printing.

Title: Information transmission system
Inventor: NAKAZAWA TAKAYUKI
IPC: H04Q3/545
Filed: 1991-04-23
Abstract: PURPOSE:To prevent omission of taking-in of information by efficiently taking in information on the reception side. CONSTITUTION:A transmission side (second information gathering part) transmits m-bit change presence/absence information A before period information. Respective bits A1 to Am of this information A indicate the presence or the absence of the change of contents of groups B1 to Bm, which are obtained by dividing period information into m by n bits, from preceding those as '1' or '0'. The reception side takes in only contents of changed groups, namely, groups corresponding to bits '1' out of bits A1 to Am of change presence/absence information A in accordance with change presence/absence information A.

Abstract: PURPOSE:To form a buried layer with good controllability in simple steps by selectively forming a diffused layer on the surface of the mirror-polished first semiconductor substrate, and bonding to the mirror-polished second semiconductor under clean atmosphere. CONSTITUTION:A n<+> type layer 22 is selectively diffused on the surface of a mirror-polished p type Si substrate 21. The layer 22 becomes a collector buried layer.

Title: Liquid level detector
Inventor: INOBE KAZUHIKO
IPC: G01F23/292
Filed: 1983-05-26
Abstract: PURPOSE:To enable miniaturization of dimensions and positive detection of liquid level, by accommodating light emitting and receiving elements in the same housing and installing on one side of the housing reflecting plates in an opposed manner. CONSTITUTION:In case when a level of ink 8 is located in a lower position A of a photo-sensor 10, a ray of light from a light emitting element 11 is reflected by a reflecting plate 16 and reach a light-receiving element 12 through air between a housing 9 and a reflecting plate 16. When the level of ink 8 rises up to a line B position, a ray of light of the light emitting element 11 reflected by the reflecting plate 16 reaches the light-receiving element 12 through ink 8 existing between the housing 9 and the reflecting plate 16. A magnitude of light reaching the element 12 is greater than that when the ray of light passes through air on its light path and consequently, by the quantity of light received by the light receiving element 12, it is possible to detect whether the ink level 8 is located above the photo-sensor 10 or not.

Filed: 1994-04-07
Abstract: PURPOSE:To stop travelling without causing an overrun by furnishing a means to brake at decelerating speed higher than usual and actuating a brake means at the time when residual distance is smaller than emergency stop distance in accordance with current speed. CONSTITUTION:A travelling carriage of a stacker crane travels at high speed Vh, when it approaches an end edge of a track, it controls output of an inverter to drive a travelling motor and is decelerated at normal decelerating speed B. When speed reaches creep speed Vc, it stops deceleration and transfers to stop control. If current speed does not reach the creep speed Vc, residual distance is found from a pulse value of an encoder 5, furthermore, emergency stop distance Sel in accordance with the current speed Vn is found from an emergency stop distance data 7 and the residual distance and the emergency stop distance are compared with each other. When the residual distance is larger than the emergency stop distance, normal deceleration is continued, and when the emergency stop distance is smaller than the residual distance, emergency stop is carried out by actuating a mechanical brake 2.
