Net Income per Share.  Basic EPS is computed as net income 
divided by the weighted average number of common shares outstanding 
for the period.  Diluted EPS reflects the potential dilution 
that could occur from common shares issuable through stock 
options, warrants, and other convertible securities.  The 
following is a reconciliation of the numerator (net income) 
and the denominator (number of shares) used in the basic and 
diluted EPS calculations.

PART I - FINANCIAL INFORMATION

Item 2 - Management's Discussion and Analysis of Financial 
	 Condition and Results of Operations

Certain Factors.  This report contains forward-looking statements 
within the meaning of Section 27A of the Securities Act of 1933 
and Section 21 E of the Securities Exchange Act of 1934.  Actual 
future results could differ materially from those discussed here 
and elsewhere in this report.  Factors that could affect future 
results include general economic conditions, both in the United 
States and foreign markets, economic conditions specific to the 
semiconductor industry, the Company's ability to introduce new 
products, its ability to enhance existing products, its ability 
to meet the continually changing requirements of its customers, 
its ability to manufacture efficiently, its ability to control 
costs, and its ability to maintain and enhance relationships 
with its assembly and test subcontractors and independent 
distributors and sales representatives.

Results of Operations

Net Sales.  Net sales for the quarter ended June 30, 1998 were 
$13,001,000, a 6% increase from $12,313,000 of the same quarter 
last year.  The Company's sales growth has been generated 
principally by new product introductions in the Company's 
targeted markets of medical ultrasound imaging, 
telecommunications, and flat panel displays.

In this quarter, approximately 56% of the Company's net sales 
were derived from customers outside the United States.  All of 
the company's sales to international customers were denominated 
in U.S. currencies.  There was no currency exchange exposure, 
however as the US dollar continues to be strong against other 
currencies, many international customers requested and received 
modest price concessions.

Gross Profit.  The Company's gross profit for the quarter was 
$6,094,000, compared with $5,633,000 in the same quarter of 
last year.  As a percent of net sales, gross margin for the 
quarter was 47%, a 1% increase from 46% when compared with the 
same quarter last fiscal year, primarily due to cost control 
measures taken.

Research and Development.  Research and development expenses 
increased 9% to $1,501,000 for the quarter ended June 30, 1998 
as compared with $1,376,000 for the same quarter of  last year.   
As a percent of sales, research and development expenditures 
increased slightly to 12% compared to 11% for the same quarter 
last year.  The increase was related to new product development 
and the Company expects that new product development 
expenses will increase during this fiscal year.

Selling, General and Administrative.  Expenses for selling, 
general and administrative were flat at $1,692,000, or 13% 
of net sales, compared with $1,634,000, also 13%, in the 
same quarter of  last fiscal year.  The dollar increase in 
this category was due to a slight increase in payroll expenses 
as a result of headcount increase in the sales department.

Interest and Other Income.  Interest and other income for this 
period were $441,000 compared with $371,000 last year.  Higher 
amount of funds available for investments contributed to this 
increase in interest and other income.

Provision for Income Taxes.  The Company's effective tax rate 
for the three months ended June 30, 1998 remained at 34% 
compared to the same period last year.

Overview.  Total assets grew to $69,137,000 as of June 30, 1998, 
up from $66,629,000 from quarter ending March 31, 1998.  The 
increase is due to favorable operating results for the quarter.

Liquidity and Capital Resources.  On June 30, 1998, the Company 
had $34,854,000 in cash, cash equivalents, and short term 
investments, compared with $31,512,000 on March 31, 1998.  
This 
<PAGE>
increase is mostly due to positive cash flow from 
operating activities of $3,991,000 consisting principally of 
net income of $2,207,000 plus depreciation of $772,000, 
provision for doubtful accounts  and sales returns of 
$254,000, decrease in receivables and prepaid expenses of 
$868,000 and an increase in liability accounts of $218,000, 
and partially offset by an increase in inventories of $167,000 
and an increase in the provision for obsolescence of $161,000.  

Net cash used in investing activities in the first quarter of 
1998 was $6,074,000 which consisted primarily of purchases of 
short term investments and purchases of equipment.  

Net cash provided by financing activities was $25,000 which 
consists of proceeds from exercises of stock options.

The Company anticipates that available funds and cash expected 
to be generated from operations will be sufficient to meet cash 
and working capital requirements through the end of fiscal year 
1999. 

Year 2000 Compliance Risks.  The Company is aware of the issues 
associated with the programming code in existing computer systems 
and software products as the millennium (year 2000) approaches.  
The "year 2000" problem is pervasive and complex, as virtually 
every computer operation will be affected in the same way by the 
rollover of the two digit year value to 00.  The issue is whether 
computer systems will properly recognize date-sensitive information 
when the year changes to 2000.  Systems that do not properly 
recognize such information could generate erroneous data or cause 
a system to fail.  As a result, many companies' software, computer 
systems and other equipment may need to be upgraded or replaced 
in order to comply with such "Year 2000" requirements.  The 
Company is utilizing both internal and external resources to 
identify, correct or reprogram, and test the systems for year 
2000 compliance.  It is anticipated that all reprogramming 
efforts will be completed by December 31, 1999, including and 
allowing adequate time for testing.  This process includes 
getting confirmations from the Company's primary vendors that 
plans are being developed or are already in place to address 
processing of transactions in the year 2000.  However, there 
can be no assurance that the systems of other companies on which 
the Company's systems rely will also be converted in a timely 
manner or that any such failure to convert by another company 
would not have an adverse effect on the Company's systems.  
Additionally, the Company's net sales could be adversely 
affected if the Company's customers or potential customers 
reallocate spending from the Company's products to their 
efforts to resolve the Year 2000 issue.  Finally, the Company 
utilizes third-party equipment and software that may not be 
Year 2000 compliant.  Although preliminary estimates indicate 
that the Year 2000 issue will not have a material impact on the 
Company, there can be no assurance that the Year 2000 issue, 
due to the above factors or other unforeseen consequences, 
will not have a material adverse effect on the Company's 
business, financial condition and operating results.
